Just name the sword "Soulslayer" or "Demonbringer" or "Bloodblade", and your carbon fibre sword will remain edgy forever.
Nah, only a few years until the sword graduates from Middle School. To truly make it stay edgy forever, you need to forge in the fires of its parents corpses whilst quenching it in the blood of its favorite dog, on the peak of a volcano under the rule of the Evil Overlord before it is tossed away to the protagonist as a defect.

It is an interesting question. If Firearms never existed what kind of Swords and weapons would be used today?
air guns would probably fill the role of firearms. there was even a time where they outpreformed firearms (but were more expensive).
after rubber bands were created you would probably have war elstic slingshots and sling shot guns (similar to what you would find on the slingshot channel)
TREBUSHET ARMED TRAIN
Full auto carbon fibre throwing knives.
If its just gunpowder technology, we would probably use other potential energy alternative like gasoline or bateries to make guns when they were discovered.

I see this material and raise you: metallic glass. It's a metallic alloy that's been cooled so incredibly quickly that it forms no crystals and becomes an amorphous solid like glass. It's incredibly flexible but always springs back into its original position because it's no longer plastic like every other metal. Due to its ludicrous hardness, it can theoretically be honed into a _significantly_ finer edge. As of now, the only know manufacturing method is to form it into very long, very thin sheets, so you can't have a blade made of solid metallic glass. I'm visualizing a blade made of many layers laminated together with some kind of low-temperature binder like epoxy or resin. Theoretically (and I'm no material scientist or engineer so forgive any misconceptions and leave a counterpoint in the replies), as the edge chipped, which is inevitable and expected with a brittle edge, it would reveal the layer beneath which may be just as sharp. Since the layers are ridiculously thin, the jagged edge that would form would only be jagged on a microscopic level and could be reasonably easily sharpened due to being hard but not too hard. This material may also be used in a composite construction like you mentioned with carbon fiber or even regular steel.
The White Dragon en.wikipedia.org/wiki/Amorphous_metal
It's an interesting idea.
Amorphous metal. Metal glass. No crystalline structure so no defects that make standard crystalline metals weak. Specifically, no grain boundaries and no dislocation since the metal is one cohesive chunk with no layers or discernible structure. Their tensile strengths and elastic strain limits are also higher than crystalline metal. This sounds pretty good so far but there is an issue with these metals.
This issue is that, as you might expect, the metals fail suddenly when placed under tension at room temperature. That's no good for sword fighting. They are not ductile at all at room temperature.
All is not lost however, a MMC(Metal Matrix Composite) combining this amorphous material with regular crystalline metal(CPM-M4 or Elmax ?) could result in a blade that has the best of both materials' qualities.
@@tylerphuoc2653 I don't have the time to read it now, but you've just provided me a _whole_ lot of reading materials. Thanks man!
@@candyman9635 I was reading about a recent (2016) titanium-gold alloy that they are just now looking into.
In typical metallurgy, when you work with metals or make an alloy you simply bring them to the highest melting point needed for the metals to melt. Some lab tech did something different. She brought the titanium and gold to their boiling points then mixed them (I don't know the ratio). Bringing them to the boiling point caused them to combine in a different molecular arrangement than when normal (just the temp needed to melt them). The alloy was amazing. Grinding in a diamond crucible didn't work. They see uses in medical and drilling. Anyway, I wonder how this alloy would do. Normal gold-titanium alloys won't work, this might.
@@DragynryderMW If you can provide a source or an article or something about this alloy I'd love to see for myself.
Perhaps you've forgotten the most important question: What was the primary infantry weapon that was obsoleted by firearms? It wasn't a sword, it was a pike. And here is a weapon where carbon fiber actually imparts a ton of advantages. You can gain a lot of additional length, possibly to the point that it is almost ridiculous. There is no added complexity as there is in the sword's fitted and joined razor blades. With modern metallurgy mentioned here, a tip can be made that's incredibly light and strong and sharp and all the things it needs to be. That is what you'd want on the futuristic battlefield without firearms.
Real life has always been 'How far away can I keep the person trying to stab me?'
That said, you'd also need to invalidate flamethrowers (Pike Hedge, now burning hedge.) and crossbows.
@@erikvale3194 that would also somewhat depend on what technology made guns ineffective. I'm thinking of the energy shields in Frank Herbert's Dune. Those, I'm pretty sure would stop flamethrowers, and even crossbows. They'd even stop a melee attack if you swung too fast.
@@rayanderson5797 That type of shield would cook anyone inside it.
@@mrsillywalk if a knife can go in, then air can go too
@@whimsicallychrissy you could just put "dune shield" on youtube and see how the shield works
at least in the movie it seems like only slow moving objects can penetrate, as the stabs get reflected, but you can insert your hand inside the shield before attacking
and the comment i was addressing said the shield would cook the person, not that somebody would use a flamethrower, and as you guessed ammo wise a flamethrower is not a good weapon, specially in a desert planet where the fire can't spread, nobody uses a flamethrower against a single target, the fuel uses to much volume to be transport across the space to be used as ammo, i don't even know if they still use petrol based fuel
Edit: spice is not fuel
Maybe you should talk to Kyle Hill about trying to get such a composite blade made so that it can be properly tested in suitably scientific conditions. And since Kyle is definitely not a supervillain, you don't even need to worry about what he might do with the data...

Shad Fact: Shad slapped the leaning Tower of Pisa gently knocking it perfectly up and back down the other. Feeling a little bad, he rotated the whole building around with a flick.
Remember he also propped it up with a pommel to keep it from falling down!
Another fun fact: During a vacation to Canada, Shad was asked to demonstrate a pommel strike on a mannequin. The resulting crater was filled with seawater and was named after the sad sap who asked for the demonstration. This is how the Hudson Bay was formed.

Carbon fiber is a really bad material for any kind of weapon. Although it has really high strength under static loads, it's impact strength is absolutely horrible. I'm a resin supplier in the automotive industry, and we work with a lot of glass-filled composites that approach the strength and impact resistance of metals, but carbon fiber is well known to be entirely not viable for any application that requires even a bit of impact. It's great for something like brackets or frames that handle weight or other constant/gradual loads, but smack it and it will shatter.
If you were to make a sword out of carbon fiber, it would snap the moment you tried to hit something with it. The only way to make it strong enough in impact to survive would be to make it far *thicker* than steel, not thinner.
Yep de-lam is a major problem with composites, the fibers have very little compression strength hence the resin but resin can facture. then you have the so fun UV problems. oh plastics so good but so bad.
@@calmterror To be fair, there are a lot of plastics that can handle UV pretty well, especially things like nylon (especially with a bit of carbon to help absorb the UV). Delamination also becomes much less of an issue if you use impregnated composites such as chopped fibers instead of large weaves.
Something like a glass-filled nylon would actually be a very interesting material to make a sword out of due to the ability to literally injection mold it over a tool steel blade insert. As a material it wouldn't be as good as steel, but it would be an insanely fast product to manufacture, as once the mold is created, you could mold a probably dozens of swords per hour, and for far cheaper than any steel machining/casting process.
@@Drazex Well to be fair if you put enough UV absorbers into any plastics they can handle UV pretty good. Plastics are good in some cases bad in others. now the injection molding sure it is fast but so is just have a large plate of steel that can have a bunch of swords stamped out of. which out of all of this would steel still be cheaper to make a sword from. petro chemicals and fibers are not cheap. funny how sometimes the material you started with ends up being the best and cheapest option.
@@calmterror But die-cutting has it's own problems, as you're not finished manufacturing then. You're not going to be able to mass-produce die-cut tool steel, at least not without going through a massive number of expensive tools, and the softer steel won't hold an edge well. So you're going to have to deal with both the die cutting and the additional sharpening process on each sword, and it'd be a lot more work overall to get multiple metal materials to work well together if you wanted a tougher core with a harder edge.
My company frequently replaces metals with plastic because injection molding to replace metal parts is objectively cheaper when the molds and manufacturing processes are considered.
Steel's certainly still the best option for swords, don't get me wrong, but a glass-filled plastic for injection molding is likely to be cheaper to produce overall if you want something like a tool-steel edge.
Yup, I was looking for this comment. It's got *structural* strength, that's it. Kind of how wood is "stronger than steel" (in some aspects, by strength to weight ratio). Wooden swords for all! If anyone did make a carbon fiber body with sharp blade inserts on the edge, you'd just have a sword with a "blade" that would probably get chopped off as soon as you used it to block an incoming attack. No dice.

Modern day Shad: Still can't find anything better than steel to make a sword out of.
Me: "maybe you could improve projectile weapons?"
@@FireStar-gz2ry You might think so, but the best weapon we can think of is still throwing rocks at enemy from afar (Rods of Gods).
@@vlads3283 Well its tungsten not some random rock.
As someone who regularly works with Carbon fiber: No way in Hell. I can't imagine how you'd keep an edge on it, and if you thought delamination when forging swords was bad delamination in CFRP (carbon fibre reinforced polymer) when hittting it is much worse. I doubt a CFRP sword would be able to withstand a couple of swings before breaking at some point.
The issue with CFRP is that it is very strong... in the direction of the fibres. In the other direction, it's as strong as the resin, which is to say, not very. While it might be able to take a hit edge-on providing the edge was steel (which wouldn't work anyway because you wouldn't be able to fix the steel blades into such a thing sheet of CFRP), a hit on the side of the blade would crack it easily.
Exactly what I was thinking. Except I'm stupider and can't use words good.
There are some better composites that can be used, but they are currently way overpriced and still aren't really suitable. Impact resistance is poor, which is a problem for car parts and things actually, failing more often than expected.
@@carbon1255 I see. But this brought an idea to my head. Instead of solely using carbon fibers on the composite , how about using some fibers that aren't carbon fiber , a strong but softer material , like aluminium , in the composite ? Would it give it some flex ?
Along the lines of carbon fibre + steel inserts, I theorize that the forces transmitted to the main 'sword' via impact to the cutting inserts..... ... wouldn't be kind to the carbon fibre.
@@carbon1255 or maybe even instead of using just the carbon fiber , using a very high carbon content substance that also includes other materials that will give it springiness and make it softer , kind of like how steel is made , but reverse , and use it's fibers for the composite.

Lord Shadington, First of his name: Right, right. But you know, the interesting thing about carbon fiber...
Not gonna lie. I have a goal for myself that now that I have had my Lumbar spinal fusion competed (from a 20 years ago back injury), I have set a goal to lose most (hopefully all) of the weight I gained, and as my reward to myself for losing the weight is going to be an albion sword (or one of like quality) and my own armor, so I can find excuses to wear them as often as possible; just like shad is here.
You mean shad stands next to a "castle" in his brigadine... Really sorry to say that but I looks so bad, like a cut out movie set piece for a budget film... The whole picture would look so much better without it
That looks like a toy castle
For tools, the disposable razor has effectively replaced knives for more applications. This is largely due to modern improvements in manufacturing and precision. Considering this, would it be practical to create a sword with disposable parts or even a disposable sword (similar to disposable razors)?

Because a mace with low weight sounds like a good idea?

Correct me if I'm wrong, but I thought the weight of a mace was important for its bludgeoning capability. Would a carbon fiber mace head need to be larger to compensate for its lack in weight?

Wasn't one of bronzes biggest weaknesses being that it was extremely soft compared to iron (and later steel)?
@@patchmoulton5438 Indeed, steel is a far superior material for swords.
Although he said "functional", not perfect. Some of the greatest empires of history used bronze weaponry to great effect.
@@sirreginaldfishingtonxvii6149 I think that was a slip of the tongue, for the most part. When he said functional, I thought it was more in line with most effective. I know bronze is still being used cutting tools, though for the life of me I don't know why. It looks pretty? It's actually easier/ cheaper? Anyways, I think he was going off on the idea that if you pit two equal armies against each other but one has steel and the other just bronze, 9 times out of 10 the steel army will win. As a weapon of war, could you consider a bronze sword 'functional' when compared to a steel one?
@@patchmoulton5438 It was probably just a simple mistake, but we decided to joke a little about it anyways. I've heard Shad talk about bronze weaponry before.
Either ways, the steel army (if their weapons would be the only difference) would very much most likely win, like you say.
I'd still say you could consider bronze weapons to be functional though. Even if they're made out of a softer metal, you can still kill a man with them, and do so effectively. Steel is just _more_ effective, and when there was no reason for bronze to be used anymore people naturally switched.
No idea about why you'd use it in modern tools though aside from the aesthetic. I'd have to look that one up.
What you call "stiffness of the material", in scientific/engineering terms, is Young's modulus. That of steel is around 200GPa, and that of the most extreme carbon fiber is around 300GPa. It's not orders of magnitude stiffer to begin with. And most importantly, the stiffness of a flat bar is linearly proportional to Young's modulus, but proportional to thickness cubed (see "second moment of area"). That is even though the most stiff carbon fiber is 50% stiffer than steel, you could only make your blade 12.5% thinner. The benefit is only extremely marginal, and seriously not worth the hassle. Actually, it's much more interesting to think the other way around, and take advantage of the lighter density to make wider and thicker blades with the same grind angle, resulting in a much stiffer blade that cuts and chops just as well.
As for the edge, "tool steel" is just the widest category. I guess you meant High Speed Steels (HSS)? The problem with most of these steels is they are indeed brittle, and require an almost obtuse geometry of edge to resist the stress of normal use (drill bit lips have around 60-70° of edge angle, cutting dies are almost 90°, etc). Milder/older tool steels like O2 and such can be taken to normal sword edge geometry, but it won't make a huge difference with a well heat treated 1095. Intrinsically, a sword fight will be traumatic to an edge, no matter how good of a material you choose.
In the modern world, the most relevant sword is the machete. It's dirt cheap to produce, extremely rugged, and can be designed in a wide variety of ways. The Marbles MR374 is an excellent substitute for a briquet, for example. But if I were to take advantages of modern materials, I'd basically make a large titanium blade (but steel edged - brazed) Flyssa with a D guard (grenadier hanger style). It's got stab, it's got chop, it's got everything you ask for.
I agree and I think if we wanted to make the best possible modern sword it would be made similarTo historical swords but I’d say like made out of cpm3v or maybe cpm 1v
Remember that you don't cut with the flat of the blade. If you keep the blade in the original width while only reducing the thickness in the direction perpendicular to the load, you only reduce the stiffness linearly. Thus, 33% thinner but equally wide blade would still be equal to the original in stiffness if made out of 50% stiffer material.
That said, buckling might become an issue if the blade is made too thin.
If i'm following, a thinner blade may bend and looses you mass. A wider blade will decrease chopping power because the material being cut must be separated further.
So the best bet for lighter stonger materials would be longer blades (so the review of sepheroth's sword)
Like your probably better of with a electric high rev chainsaw XD
Or if machine guns do not do it? Then ramming with a vehicle / bigger guns?
Or some explosives. Or better yet why not make a law to stop them??? That works!
But normal Steel swords that are high quality are grate as they are. There is no good reason to try and push it further as the returns are very low for the effort.
@@TheDiner50 I'm not sure if you're joking, but on the off chance you're not, the presumption that a "law" could possibly prevent people from getting their hands on lethal weapons is categorically false, as proven by, well, all of human history.
There’s a reason why we don’t put the ”insanely
hard” steels onto things which are going to experience shock loads. They tend to shatter and send out high speed shrapnel. That’s why you don’t have hardened steel hammers and such. This would happen to the edge of this sword too, it would shatter and splinter off.
As for the carbon fiber, you’re talking about a carbon fiber resin composite all this time, you can have a different matrix than resin (the resin is what dented when you tried to cur with it, since it’s just plastic). what we would do if we were building swords today is a metal matrix. Google ”metal matrix composite”.
A far simpler way to make a sword more deadly is to simply run a few amps through it.
Swords, no matter what material they are made off, are limited by the strength of the user. If we still relied on mele weapons today in warfare we would still not use swords, at least not in the traditional sense. We would use weapons with it’s own power supply, like chain saws (though chain saws made for cutting trees are horrible mele weapons since cloth can cause them to jam).
But we could use hydraulic spears so that when the tip makes contact to your enemy the spike shoots out very quickly, adding more power than any human ever could. Basically more power is always better, a simple sword will be outperformed by any mele weapon where you’ve added power. I think ”Robot wars” is a good inspiration for what those kinds of weapons might look like, since it’s basically the exact scenario you’re describing: ”What is we can’t use firearms”.
So I’m guessing spinning wheels of death on a stick would be a popular weapon
Replace chainsaw with a reciprocating saw, that should prevent the jamming :)
Suthriel That’s one way. Not sure how well ultrasonic cutters work on metal, but it could be an option to put a lot of cutting power into the sword. From the ultrasonic cutters I’ve seen they go through rock like butter; though they require some very precise circumstances so might not work as a weapon.
Whirligig Saw. Handle which has two spinning circular sawblades at its end.
A pair of insulating boots and/or just well-thoughout armor would kinda kill the electric sword. Assuming everybody would be somewhat armoured on a melee battlefield, blunt weapons + powerarmor might be the best (reinhard :P). This also eliminites edge retention problems saws might have. I do like the electric sword for unarmored opponents. It would be the weapon of choice against civilians and support personell.
JesseB3r You’re missing the point of electic mele weapons, it’s still a regular mele weapon. No matter what mele weapon you use to defeat the armor, if you take that same weapon and apply electricity it does not matter if you pierce someones head or hand, once you make skin contact you win the battle. So an electric weapon would be very effective against armor specifically since you just need to pierce a small hole to get the electrodes onto target.

Carbon fiber is a "COMPOSITE" material. The structural part is the Carbon fibers themselves. Those will give the stiffness and strength (depending on the fiber orientation). But the 2nd part of the composite is the MATRIX material (what binds the composite). Most Carbon Fiber Composites are made using polymeric (PLASTIC) matrices.
Plastics that bond very well and can be made relatively cheap with carbon fiber are EPOXIES...which are brittle and not that strong....
Cool information. Thanks for sharing
Is it possible to make Carbon Fiber out of steel then?
@@StarboyXL9 Then it wouldn't be carbon fiber, it would be a steel fiber composite. And unless you're chasing some particularly specific properties, like a material that's strong in one direction but weak in another, you might as well just go with formed or machined steel at that point.
There are some forms of carbon fiber that incorporate metal fibers as a component of the weave. Carbon/titanium composites have been used in some high-performance automobiles.
@nonya business I think that is the point where the manufacturing process is so long and so expensive that the marginal improvements gained are completely not worth it. It's the kind of thing where IF there were advantages, it would only be deployed for the highest tier of specialists and only in certain circumstances.
A lot of these more exotic material composites not only use incredibly expensive base elements, but they require enormous amounts of waste and additional materials to create the desired results. An example would be a ceramic/metal hybrid that is nearly uncuttable that was developed recently. It requires that, iirc, the metal be grown around ceramic balls using an aluminum/titanium foam starting with sintered metal. The cost/time per unit is insane.

If you want to diamond-tip somthing, perhalps a peircing weapon, like a spear or arrows.
If we're talking high-tech futuristic materials, super strong and thin, you want to look up Graphene.
I'm an engineer who works with composite materials including CFRP. Carbon fibre itself is basically just a cloth, which is laid up and infused with a resin/polymer. It has exceptional strength to weight in tension. However it's not isotropic like steel, the strength lies in the direction of the fibres: what you show in this video is a woven carbon fibre, which while still incredibly strong (not breaking), it's actually more prone to bending than steel, if you made it as thin as you've shown it would be exceptionally flexible.
and carbon-carbon composites? (carbon fiber + graphitized binder) They are very strong and somewhat brittle.
I assume that CFRP stands for "carbon fibre role-playing".
How would you use graphene in a sword? I'm sure technology has gotten better, but I remember salesmen pushing graphene enabled cutters. They were horrible. I'm not familiar enough with the material to understand what alloys you would use it in, and/or why.
I'm Iegitemately curious. I'd rather you didn't send hate or bs my way.
I think it would be a bit too light honestly. I maybe if it had a tungsten core with graphene layered on top.
@@SpectrumDT CFRP stands for "carbon fibre-reinforced plastic/polymer"
I've actually thought of this precise matter for quite sometime and has made a pretty extensive research on the matter. According to my findings, the best possible sword to be made today should be made using a carbon Kevlar fiber composite for the optimal lightness, toughness, strength and rigidity, with pure tungsten blade coated with graphene for the sharpest edge that has the grratest edge retention and has titanium and steel handle for the best weight distribution with a non slippery coating around it.
should be a cricket bat sized width 4.25'' with length of 32'' give or take an inch, make it with a diamond core wrapped in carbon fiber kevlar so its bulletproof, can be sharpeded to the thickness of "an atom" and we have our selves a harry potter syfi film in the works lol .

Absolutely nobody:
*Hideo Kojima pumping his fist into the air holding Raiden's sword*
"If we could invent some sort of advanced technology that could block bullets, hut not melee weapons..."
**Eyes Dune movie trailer**
Of course that armor that can stop bullets can also stop blades (f we don't speak about somehow magical blades or psychc-power-enhanced strikes, of course). Undoubtably. But if an armor strong enough that it can protect against any hand-held gun (including .50cal, .950JDJ or maybe even RPG rounds) making them have only movement, but not destructive effects on you, blades will come back to favour because of one thing. Every armor has it weak spots, typically armpits, crotches or inner sides of joints in general (not a visor in today's helmets, it will be covered with a strong transparent thing, maybe alon glass), and it's much more possible to stick a sword into the gaps of the armor than shooting there with a gun - which will be almost impossible from a front and from a distance.
The bottom line: Armor block blades but with a blade you can bypass an armor therefore blades can beat a literally bulletproof armor.
@@narciska0 >Of course that armor that can stop bullets can also stop blades
That isn't actually true. We outright have real-life examples of bullet-vests that can't stop knives.
There are of course versions that can stop knives too, but they have some cons of their own.
@@narciska0 Modern militaries aren't gonna just toss away the advantages of ranged combat. If we had armors that blocked bullets but not blades, that doesn't mean they'd revert to melee weapons. Rather they'd just replace bullets with bombs i.e. assault rifles with grenade launchers. Good luck blocking that.
the slow blade penetrates the shield
@@KageRyuu6 If it's an x-ray laser anyway, or if you're talking about transparent forcefields like in Dune. (I don't remember if they were transparent in the book(s).)
Mirrors block lasers. There are some types of light like gamma rays that there is no known way to build a mirror for, but it's also difficult to make lasers for those frequencies because normal lasers function using mirrors.
That being said, I know that x-ray lasers do exist and that x-rays can only be reflected at shallow angles. Because of this, x-ray lasers are apparently usually made without using mirrors. This means that it is actually possible to make what nowadays at least is an almost unblockable laser, although someone could probably block it with some kind of curved mirror x-ray "lens" shield using similar techniques to the ones x-ray telescopes use, just bending x-rays away instead of focusing them.
X-ray lasers can already be quite powerful, too: Not too long ago I read about this experiment related to modelling the interiors of Uranus and Neptune where they used an x-ray laser to separate some polystyrene into diamond and hydrogen in under a nanosecond: escholarship.org/uc/item/1cf3b8v4
If you're looking for an edge material that'll keep sharp, I feel like you can do no better than a tungsten carbide or something. Plus tungsten is very dense so it could partially offset the loss of mass by using carbon fiber.
I would think silicon carbide over tungsten carbide. A bit more shear strength.
Tungsten Carbide is stupidly strong too. Probably also very difficult to sharpen though.
Erik S Also very brittle.
Redshift VS Not many. Tungsten is really dense.
@Redshift VS unsubscribed cause the battery on your power armor would drain faster carrying 20 tungsten blades with thermite charges than it would if you just used one 10x size tungsten blade
phys.org/news/2013-05-brittle-material-toughened-tungsten-fibre-reinforced-tungsten.html
Redshift VS, it makes more sense to heat the sword up to scorching temperatures using electric coils inside than it does to turn it into a big thing of thermite. Thermite is cool, but impractical for a sword as if you want to burn the enemy, make it hot enough to burn a person, if you need to blow something up, use a grenade.
Bullet blocking leading to a rise of bladed weapons is a description of Dune.

Thanks, Shad. Your channel is incredible. Thank you for all the hard work you are doing.
One of the coolest blade ideas in recent sci-fi that I've seen were the "fusion blades" from the Deathworlders series by Hambone. In universe they've figured out how to manipulate the electro-static force (the force that makes objects able to interact with each other physically, in very simple terms), this allows them to essentially create force fields that are as physically real as any object you can hold in your hand. However those fields can have properties that regular physical objects cannot have, such as being incredibly strong and thin. Fusion blades are an example of this, as they're effectively single atom thick blades that cannot break or bend (they also are very hot, though I'm unclear on if this is intended or not).
It's a cool example of taking a speculative technology and carrying it to it's logical conclusion. These force fields are used for a huge array of technologies, from the aforementioned fusion blades to "coolers" that actually work by slowing down time inside the device, such that you can take a pie out of the oven and put it in the box and ten years later open the box and the pie is still hot and fresh as the day it came out (because for the pie only a few seconds have passed).
It's often disappointing for me when authors gloss over or straight out ignore the practical applications of their universe's unique traits. In fantasy settings with magic you could have truly unique and impossible technologies but everyone settles for fireballs or killing curses. Why not firearms that use rune magic to shrink their ammunition to a comically small size and weight, then removes the enchantment to bring them back to full size when fired? Or wizards using ice magic to create magical air-conditioning?
Best coment in this section. Really gave me food for thought in the RPG campaign I'm writing!
The 'fusion blades' sound like Deaths sword on the Discworld.

Sword or not still killed Spaniards with a steel breastplate and helmet, and left horrible easily infected wounds on others.
I agree they do have more qualities of club or mace than sword. However the were swung like swords had one or two striking edges so edge alignment was important. Maintenance was much easier though, chipped and damaged obsidian pieces could be replaced by a warrior in the field who likely knew how to nap stone and obsidian.
@@Yora21 A lot of people argue about this, and classifications of it are mixed, but for me personally, it's a club. All swords have one thing in common, and it's a blade. The macuahuitl is wood with embedded obsidian blades.
Using that logic, we could just take a European club, put blades on it, and then call it a sword when it'd just be a bladed club.
ya, obsidian can't make a sword. it can make a sword EDGE, which is kinda what they did. those who are saying it is just a club, that would put Shad's idea in the club realm too, since it is a blunt object with sharp edges added.
Heya shad, in case you want some of the definitions:
flex -> Stiffness or young's modulus
edge damage or scratches -> hardness
absorb blows -> toughness
force applied till it breaks -> tensile strength
bending permanently -> yield strength
permanent shape change -> plastic deformation (ductility can also be used loosely of this)
sword -> sword
Best sword will be using a Carbon Fiber - Polymer Composite sword center fuller/ridge. With an edge made of Carbon Fiber - Ceramic composite lined with diamond abrasive particles for improved sharpness.
YEP. Exactly my thoughts.
True how ever to improve this even farther instead of dimond we should use lonsdaleite as it is 58% harder then dimond how ever getting this metterial is very difficult as it only forms when something is hit by a meterite made of pure carbon. The thing getting hit must have a strong enough atmosphere in order to meat the outside of the metiorite.
Or just use carbon fiber with a metal matrix eg steel much simpler, cheaper and effective

There is something called an "iron whisker" or mono-crystalline whisker, where you take a thin line of iron molecules and have them all form a single crystalline structure. They are supposed to be extremely hard and flexible. If you took one of these that was the length of the edge and inserted it into a carbon fiber sword body, that would probably work well.

In Gamer’s terms: As materials get harder, their Defensive stat goes up, but their HP goes down.
Up to certain point - if you make armour hard enough it will be more detrimental as its brittleness will cause more spalling (it can be mitigated by layer of more malleable material behind - be it another plate added or plate being face-hardened

Wind of change, Glass comes close. Very useful, used in everything thing from planes to submarines to biology to astronomy to rockets to helmets to police investigation to blocking bullets. It’s also infinitely recyclable as even when it breaks, it can be melted easily. Also, we are only just understanding how to make glass less brittle and even stronger. It is also a great medium for composite materials to be integrated into.
Carbon based materials don`t do very well in radioactive environments, aluminium isn`t good either as it also turns brittle.
Shad: They are Extremely Sharp
Shad Edit: Hard
Me: "They are Extremely Hard" is now a Missed "Shad out of Context"
We still have "The ones that are INSANELY insanely hard."
To be honest it is insanely semantically convoluted... sharpness is mix of hardness and proper shape. But hard stuff tend to be fragile. It is why contrary to popular believes you can easily destroy diamond with hammer. Unappreciated advantage os steal is that it can be easily sharpened despite average hardness.
@@TheRezro Huh, didn't think about that, so basically Steel is more Convenient. There can be Sharper or Harder Materials, but Steel fits perfectly at being both A Good Durability and Malleable
@@9-bitfox Yup. Plus broad range of options and ability to create spring steel, what highly increase durability of weapon.
Carbon also becomes brittle when exposed to heat I believe. When cutting with significant force the blade heats up, especially locally. One of the reasons SpaceX went back to steel is in large part to it holding out well in both high and low temperatures.
As a machinist who's worked with steel tools and carbon fibre manufacturing... I don't think that the two would behave well together at all with the kinds of flex that the carbon blade would experience. Razor blades are not 'hardened' to the same level as HSS, etc tooling steels, and the blades still can flex. The hardened steel blades you're describing would not want to bend at all. therefore the flex would be forced to concentrate in the carbon fibers at the joints of the steel.
Also remember how your carbon knife blade chipped? That is going to be a HUGE problem along the entire joint area of the blades in the carbon composite sword. Unless you had a relief on the steel blades to allow some thickness of the carbon composite to grip into, say at least 1/2mm. If this is not addressed, then when the blade contacts a target, your steel razor would cut in, but then huge resistance would be exp'd when the carbon catches and starts splitting away from the steel.
Tooling manufactures deal with this by having comparatively huge angles between the tool and the cutting insert. Look up Carbide Insert End mills and Face mills.
NOM
(no material expert by any means but so I might be very wrong), one could maybe make it into a three part composite blade, with a blade with very high hardness and good edge retention (wondering if toolsteel would be the best choice though), and the same carbon core, only thinner (along the dimension of the blade, and give it a relatively soft material which could function as a pillow/flex zone between the two.
More composite materials would mean more ways of attaching them to one another and more points of possible weakness, but I could see it work, my initial thoughts when hearing him talk about composite swords immediately went to snowboards and skis, since those have a remarkably similar build up, (steel/metal edge with plastic cores and layers), mainly because the specifications are remarkably similar.

There is no single material “strength” property. There is tensile strength, compressive strength, shear strength, etc, etc. a material might be strong at one property, but weak in others, which can cause brittleness and other problems.
The material might also be strong only in certain directions, depending on how the grains/fibers are oriented. It’s not necessarily omnidirectional.
Lack of blade weight would could change the force dynamics, with cantilevers and ‘moments’ applied in different spots. The blade is one big lever with your wrist or elbow/shoulder as the fulcrum. When the blade contacts something, that applies torsion to the fulcrum spot.
Cutting resistance would be as much about the width of the flat as well as the width of the edge, due to friction.
Excellent point. Especially the orientation of non-uniform materials - such as fiber based ones - matters a lot.
The friction effect also depends on the geometry of the blade, the material being cut and the cutting speed. For material without pre-existing internal stress, there will be compression due to the width of the blade and thus friction matters as you said. But in some cases, like if you cut highly stretched fabric, the friction has minimal effect because the material doesn't stay in contact to it once cut.
In short: It's the obsidian weaponry situation all over again.
if you could get a large enough piece of obsidian in would be amazing.
@@FoxDren not as a single piece sword. The reason the mayans used several smaller pieces of obsidian as the blade is because obsidian is still GLASS, which breaks very easily. However, this actually makes for a more damaging weapon, as the broken shards stick into the target and create more wounds.

If we're talking about carbon, I might suggest another version; graphene! Graphene is a network solid that has an extremely high tensile strength of 130,000 megapascals, can be created in sheets as thin as a single molecule, and is _incredibly_ light and flexible. A sheet of the stuff the size of a football field weighs less than a gram. The only major drawback is that it is EXTREMELY conductive, and would basically turn you into a lightning rod.
Pure graphene is technically a semiconductor though with how easily it can be forced to conduct it might as well be a conductor but its properties can be adapted based on whatever its lined or alloyed with since you don't want to leave it exposed to air . Also the graphene sheet is itself a molecule a macroscopic molecule with atomic level thickness. ;)

ruclips.net/video/vV1sgNEmgZg/видео.html there you go. This guy needs recognition man
I am pretty sure you are wrong about the sword needs to be heavy. If you swing a lighter sword with the same speed, you will have a lower impact and do less damage.
But you can accelerate a lighter sword to a higher speed with the same force! The impact could be the same or even greater and it would be harder to dodge or parry a faster sword.
An extreme version of this is a bullet. It weights nothing compared to a sword but it can have a big impact that comes from the speed of the projectile.
If this modern sword material would be much lighter than a traditional sword you could make it much longer. You could accelerate the tip of this really long sword to a much higher speed and make a big impact on your opponents armour.
A thought I had about 9 or 10 minutes in was: we already need to make the edge of this carbon fiber-bodied sword insertable, why not make it modular? Imagine you have a sword chassis; it is a carbon fiber frame complete with everything from pommel to the exo-blade or whatever we want to call the carbon fiber frame of the blade into which we will be fitting the cutting edge. Now imagine that the cutting edge itself wasn't fused with the carbon fiber, but instead slid in place and then locked down within a machine-fitted slot and secured into the frame such that it was tightly in place but still removable. Suddenly you have a reloadable sword whose frame can be reused for a variety of cutting edges and those cutting edge could be swapped out on the fly. You could have back-up edges to use between sharpenings, you could have different edges for different applications, you could even skirt around the one flaw a diamond blade would have since the edge itself would be totally disposable once it dulls without having to toss the whole sword away with it. I think this amount of customization could have the potential to be seriously versatile and open up a lot of room for functional optimization so long as the machining was precise enough. Computer Assisted Design and high precision robotics are, after all, the primary advantages we have over traditional forging processes. Admittedly I'm an electrical engineer, not a mechanical, but I do know some things about machining and this doesn't feel like it'd be entirely outside the realm of possibility. I'd be curious to hear what others think. Maybe I'm factually wrong about the feasibility of fitting/securing them along an internal rail accompanied by pins or another fastening device, but I'd like to hear why!
I mean, most of what you said is reasonable, except the diamond part. It would still be prohibitively expensive. But yes, you could slide blades in and out. You’d have to keep them under tension at the top, or secure them with screws. Also you could do L shaped nothches on the back of the blade that slip into gaps inside the main frame.
@@bigredwolf6 , yes, the idea was to slot them into a rail within the frame, either L or T-shaped I'd imagine and then fastened down. Also, synthetic diamond is mass-produced for things like drill bits and saw blade tips for as little as a dollar a carat I believe. So they are already used for cutting tools and aren't terribly hard to mass produce, but our argument here is primarily about whether or not it would be possible to produce an effective diamond blade, not necessarily whether or not it would be cost effective, though I'd argue that isn't totally out of the question either. You'd probably cut down on the diamond used too since the part that locks into the rail would be metal and only the thin strip that protrudes from the frame and forms the edge would need to be made of diamond.
This is something like what I was thinking. The profile of the place segments would have to lap over the structural edges of the sword "body" though. Otherwise you'd essentially have micro cuts without any real penetration.
While we're at it: If we're using sectional blades on a composite body then let's add a magnetic agitational element to essentially create a vibro-blade.
@@jakeshaw4952 yes, so then the edge pieces would need to be as wide as the carbon fiber blade body is to form that proper wedge to sick the whole blade in. And I wonder if something like a piezoelectric mechanism could be used to create the vibration effect.
ryan arland That’s pretty interesting. Didn’t know they made synthetic diamond. As for the slots, I was imagining it to be a friction fit, kinda like how a Kydex holster works. With just one quick release screw at the top. As far as using diamond for an effective blade, I’ve heard people kick around the idea of making it a paste.
Another idea for the frame would be to 3D print it.
Drone guy here. I could go on and on about carbon fibre for ages but thank god you nailed it - the problem is the edge. Chipped carbon edges can be sanded back to insane levels of sharpness but you'd lose a lot of material quite quickly doing that, so the number of times you could repaid a carbon edge that way would be limited before the blade is useless. Fun fact: RC helicopters use some pretty crazy carbon fibre rotor blades. Bet you could pick one of those up if you wanted something made of carbon fibre that's instantly rather sword-like in terms of size.
Does anyone else just want a video where shad goes over his audible library and just gives book recommendations
Anything is possible with enough money and ingenuity! Who doesn’t want a sword that actually can cut through anything.
I know who. People who sell unbreakable armor. Hahahah
I’ve actually fantasized about some kind of neutron star material, atoms densely packed together, shaped into a needle the length of regular swords but only has the thickness of a few dozen atoms.
You can flap it around and because of how thin it is, any motion in any direction would be like an effective cut with the edge, and also because of its thinness it would take basically no force to cut through anything, and the enemy won’t be able to see the needle at all.
See Niven's /Ringworld/.
Neutronium is very heavy that you cannot lift a table spoon made out of neutronium material. Also it is unstable and will explode outside the extreme pressure inside the core of a neutron star.
@@kazedcat also just because it's heavy doesn't mean it's strong. Lead vs steel for example
@@kazedcat a tablespoon size would be many million tons. A neutron star is a star many times the mass of our sun that is compressed into a sphere that's 2-3000 meters in diameter.
@@kazedcat then not even a tablespoon, if I understand the idea correctly it's that if you could get a rod of neutronium thin enough to be sword weight, it'd be the ultimate weapon, this is far beyond what is actually practical regardless. And we're pretty much just making a lightsaber RN.
"All real functioning swords are made out of steel."
Iron and Bronze age: Are we a joke to you?
Carbon fiber might be very strong, but edges are very thin.
No, only to the sea's people
Anyway carbon fiber is basically cloth, imagine a cloth knife
@@myrealusername9998 Impregnated with a brittle polymer, hence the edges chipping. What we need for a CF knife is a better replacement for the current polymers.
Yes. *point and laugh.
Bronze is the OG for the first rust resistant sword metal.
I still love that armour, looks badass every time.
everybody knows that the best blades are made from Dragon Bones, because they are magic. Duh!
Time to raid a few graveyards then!
Having completed this video, Shad goes on to invent a Holtzman type body shield specifically so that swords and bladed weapons return to the forefront of combat...
So that it will be more entertaining when he brings about world peace before retiring to the Shadlands.
So thats why they replace every blade in attack on titan..
They look like box cutter blades because box cutters also do this. You're meant to be able to break off used parts of the blade and eventually put in a new blade to ensure the cutter remains sharp and effective. As for how to break the blade, I'm not sure if it applies to all box cutters, but some have a tool at the bottom that can be removed which will help.
@@shuriken188 Or, since box cutter blades are so thin and segmented you can just use your bare hands
Because in the anime they need the sharpest sword possible even if they have to replace it after every cut
They’re designed to break off in segments so the user doesn’t rip their own arm off if the blade catches.
@@hithere5553 I vaguely recall reading in the manga a long time ago that it was because of the wear on the swords since they have to cut through up to around a foot of flesh and muscle each time. Your grip will give up much sooner than your arm's structural integrity, though it would be better for your joints if the sword gave up before your grip. However, based on the lifespan of a titan hunter, I'm sure the military wouldn't care if retired soldiers got arthritis decades early.

It's not advanced technology...Its advanced skill
Carbon fiber is extremely light.
My brain: Anime sized swords!
Also it's called stropping the blade, and the leather used is the strop.
@@appa609 I know, I'm just being silly lol
lol that would be a paddle, not a sword.
Do you think that Carbon fiber plated in steel whould make a better sword as it whould be lighter then stell while still being able to keep a edge allowing you to make a one handed claymore.
@@erikburzinski8248 Don't know, but if carbon fiber has poor tensile strength then i don't think an edge of plating of steel will help. The still would transfer all the kinetic energy to the carbon fiber and it would break still. But thats just a guess. I don't know anything about carbon fiber so I won't claim i know what I'm talking about.
@@cameronbartlett856 carbon fiber has directional tensile strength meaning that you can give the tensile strength to either broad side or blade or stab. If you where to put the tensile strength on the blade then if someone attempted to stab or slap someone with broad side it whould break.
Very insightful video.
Gotta love swords, I'm thinking about getting another one soon!
you may be interested in looking at the research done into obsidian blades for scalpels. insanely sharp edges leading to superior incisions and healing time however as you stated these blades quickly become blunted, not too much of a problem for surgical blades as they tend to get chucked away anyway. However it does lead me to the fact that weapons which combines a core of light but strong material with embedded sharp materials for edges have been used in the past (and i believe you have done a video on) which is the macuahuitl, the aztec obsidian and wooden sword. As others have said this is quite an interesting thought exercise.
When I see the title: with a weighted core, then maybe
When shad talks about the vulnerabilities of the material: then use it as a core, with steel around
When shad arrives to the same conclusion ( well mostly): ahhh, perfection 🤗
Regarding diamond, then perhaps diamond dust in some kind of paste?
Diamond dust in some kind of paste ?
I understand your thinking but that is a doomed idea.
Diamonds cut well because they face the same direction, look at diamond circular saws, if you try and use a suspension of diamond dust to cut on the edge of a blade you will get nowhere. You cannot align dust to the point where each tiny chunk of diamond faces the same way with the same angles.
@@candyman9635 thanks I didn't know that.
Really, I was just throwing out ideas, and if an idea is proven undoable, then that's it.
Basically what I'm saying, us thank you
@@wiwersewindemer4437 You are welcome, please keep having ideas.
Carbon fiber as a core would be a terrible idea for durability.
1st you can't go too thin because each sheets (0,3 mm with resin basically) is basically full of discoutinuities : The more sheet, the less a failure of some strands in one is going to account in general failure
2nd you use the fiber in compression which is more prone to failure than tension because a strands wanna bulk even in its matrix: Each shock will bring off axis deformation and when the force is gone the strands retake their place and leave micro space between the sheets aka delamination
3rd being too light and rigid also mean you're sensible to vibration so each time you hurt something, the lenght is having deformation at high frequencies and that would mean cutting with a non straight edge
Carbon fiber may be out matched in strength by polycarbonate (at least when it comes to omnidirectional strength via 3d printing). Personally I've thought about a composite polycarbonate reinforced with nylon filaments through out coupled with a thin steel core running through the length and edges of steel.
Sharpening with a leather strop helps to remove the edge burr and also helps to align the edge in one uniform condition, as you stated. If you dont strop, your edge will not cut as neatly, nor will it hold its edge as long, because what you havent stropped off (which, in itself, is another form of sharpening) will be removed by whatever material you cut into, potentially even damaging the edge.
