    I'm thinking about improving V1 of the sword, which is obviously going to cut better because of the thinner profile, and making another video comparing that with a real katana. I was also swinging the final sword like a bat, because it lacked cutting abilities but it had a lot of power. Anyways Let me know if you’d like to see an improed version of V1, in which I fix all the mistakes I made, including a better slicing technique!
    Edit: I’ll do it
    Ps: the reason I kept the katana that thick, is because it would otherwise bend just with gravity. So the improved version of it is going to be shorter, kinda like a real sword.

    Hardness is not the same as tenacity, as a mechanical property. Policarbonate is not a hard material, so it is basically unable to actually retain the sharpness of the edge. That's why most of the test showed breaks by blunt weapon impacts, and not much of a cut.
    Still, it is a very cool weapon and admire your attitude of fucking around and finding out. Great video as always!

      @@kyleshinabarger8343 that sounds interesting, but I don't really know about how well would that work in terms of resisting shock. It could very well be computer simulated before actually producing something like that.
      Brittleness is guaranteed with hard materials, but that only matters to the point of the shock you actually cause to the material (and the different forces that the blade suffers during a shock). I would say, it would work much better with a smaller blade size, maybe knife sized, which didn't have to work with so much weight on it.

    Mechanical engineer here. By making a 90 degree angle between the blade and the tang in the handle you created a stress concentration there. Abrupt changes in geometry like this create localized stresses far greater than the average stress, hence why your blade snapped there. Fun video!

    • @t_g_gamerftw5075
      @t_g_gamerftw5075 18 дней назад +24

      Also, If I'm remembering correctly the flexibility of the material allows for better energy dissipation and lower impulse as the flexibility delays the force by storing energy in it's waves thus increasing the time it takes for all the force to act on the blade.
      So sandwiching it between two pieces increased the materials inflexibility at that point, and the flexibility along the axis of the beveled edge isn't good either due to it's thickness, so most of the force along that axis would have been transferred to the tang in a short amount of time, putting it under much greater stress.

      @@kyjohns8271 If by the tang you mean just the base of the blade (without cutting it), then yes! That's basically what he did in the end by just wrapping the base of the blade with a towel. If you mean keep the 90 degree angle and just wrap the smaller part, then no, the abrupt change in geometry is what induces the higher stresses. If he still wanted to cut the base of the blade to make a handle, he could have reduced the stress concentration factor by rounding the corner where the tang meets the base of the blade with a "fillet." The larger the radius of the fillet, the lower the stress concentration factor. In other words the more rounded the corner, the lower the peak stress caused by the change in geometry. The stress would still be the highest at that point, but it would be much less extreme than the stresses caused by the 90 degree angle he made.

    The right angle you cut into the blade where the handle and blade meet is what caused the break, not the added thickness of the handle. The same thing happens with steel weapons - they call it a stress riser. A rounded transition from handle to blade would help avoid it.

  • @HappyJackington
    @HappyJackington 19 дней назад +440

    The biggest reason your handle snapped off is the geometry of your sword. Having those sharp interior corners creates a stress concentrator. It's like if you have a 10 lane highway suddenly shrink into a 1 lane country road with no transition. All the cars (stress lines) have to bunch up at that point, cramming into that tiny area with no easing into it. It works when traffic is low (like swinging the swrod through the air), but the moment there's any serious traffic (like hitting the pineapple) there are too many cars trying to go into that 1 lane. For the cars, they just can't move anywhere, for your sword, it breaks.
    You will always run into this issue with making the grip smaller than the blade, but adding internal radii or some way to gradually reduce the size, will help to prevent this failure in the future. That will always be your point of failure on a sword made out of a single material. Katanas, even though they are made from one piece of steel, have different hardnesses at different parts of the blade and grip effectively making them multi-material sword.
    I bet you that if you were to take your V1 sword, even though it is a sharper blade, you will have the handle snap off even if you don't make the handle thicker. It's just a nature of your sword geometry and really only something you can learn from spending too much time reading books, or breaking things like your doing, which is how the books were written in the first place.
    I also don't want to invalidate your own discovery of adding material to the handle making it stiffer and contributing to the blade breaking. That is definitely a part of it and an awesome insight to have found. I just want to highlight that your 2D geometry has as much a roll in the strength of the blade as the 3D geometry does.

      The "cracks" that you refer to are in the handle itself, and the point of breakage is right before the guard, meaning it wouldn't make physical sense to break there instead of along the handle shaft where these "cracks" are. Furthermore the "cracks" are along the length of the shaft, while the breakage is perfectly perpendicular to it, exactly how a stress riser point breakage acts.
      Also, I say "cracks" because those are not direct deterioration of the poly through chemical reaction as you say, but simply weird light angles on the dried glue between the 3 total sheets of pol, causing a lot of refraction and reflection and the cool effect. Glue can't erode poly. The full structure would be in all fairness actually stronger, especially since the glue as a bond agent adds even more total strength between the 3 pieces combined.

    so, coming from combat robots where polycarb is used a lot, i can tell you that cyanoacrylate makes polycarb brittle.
    it was the ca glue reacting with the polycarbonate that made it turn brittle.
    there is a chemical bonding agent made to glue polycarbonate, but isn't a glue, it effectively melts the 2 pieces together making it almost as strong as if it were 1 whole piece

    Awesome stuff. Trick as well. You can flame polish the edges to make them almost transparent after cutting. Also use resin instead of super glue to bond acrylic or get acrylic weld. Look at some aquarium videos to see how that works. It melts the two acrylic parts together rather than a glue. 👍

    @MikeShake I love this project and I'd like to help you make it better. I think that there are several areas of consideration for the next version and testing methods. I have not read all 6700+ comments, so please forgive me if I repeat any. I hope some of this helps.
    1- The thickness of the "katana" and it's cutting edge
    -A katana is not meant to "cleave" through things. The curved shape of katana is meant to provide the smallest amount of cutting surface on the target. This increases the PSI of the cut. When you see a katana "chopping" through something, don't imagine an axe going through wood. Imagine the blade being dragged through the target and slicing deeper as the blade is pulled across the target's surface. More like a saw would work, slowly getting deeper by cutting along the surface, not going straight through.
    -A katana is thin so that (among other reasons) it can pass through the target with the least resistance. What you have created functions less like a katana and more like an axe, machete or kukri. However, if you decrease the blade's thickness, it will of course be weaker.
    -The edge angle is very wide, which is going to be more resilient to damage, but is not going to cut very well. That is why your cuts were messy. Of course, the narrower the edge, the more easily it will be damaged.
    -The problem you had with the blade being more visible with the shallower cutting angle would be lessened if the blade were thinner (as it would have less distance to travel from tip to flat)
    2-Target materials
    -If you're trying to make an invisible katana, you would want to test it against objects that katanas are normally tested against. I have seen a katana cut a bullet, but if I remember correctly, the blade was badly damaged afterwords. The katana was ideally used to attack soft tissue and slice deeply enough with one cut to open an artery or reach vital organs. The easiest way to do this with a blade is to stab, which is why spears and arrows were more favored in large scale conflict and most blades (that I'm aware of) were meant to deal the finishing wound with a stab. There is a very interesting history about katanas and why they were shaped and used as they were. I highly reccoment learning about them if you want to take your project to the next level.
    3-Swing technique and target fixation
    -When you're cutting with your blade I'm noticing that your swing is not at a comfortable level for you. I would reccomend lowering it so that you don't feel that you have to keep raising your shoulders at the last moment. Since training a correct sword swing is not neccesary for your project, I think it would be a waste of your time to learn swordsmanship. Of course, for your own fun and enrichment, I would say go for it LOL. But just for this project you could just work on a horizontal baseball swing or a vertical axe chop. The actual way to swing a katana takes a lot of work, and i think that your material would not do very well for the job (but I could be wrong). Once your swing is good, then I would focus on making sure that your target cant fall away so much. A lot of the energy of your swing is being dissapated by the movement of your target.
    4-Safety
    -Even when you're cutting into soft targets, you can still have material failure. Since your sword is an unknown quantity I would highly reccomend that you at least wear safety glasses at all times. Since you're not a trained swordsman, you might also want to wear some wrist wraps so that any reverberation of energy back through the sword into your hands doesn't injure your wrists.

    Alright so hear me out:
    There is another Japanese Martial Arts style that would make better use of the material, both in regards to its transparency and ability to bend.
    I believe it’s called Owari Kan-Ryu, but I just call it the Wobbly Spear technique. In essence, you grab a spear near the bottom and with your lower hand push it back and forth (sliding it through your higher hands grip) so as to cause the tip of the spear to wobble in a circular pattern.
    It helps to get past guard stances, and would likely benefit greatly from having an invisible spear used.

    Hey man, I saw a lot of comments saying that the cause of the snapped handle is because of the geometry which could be partially true, however the primary reason why this happened is because polycarbonate becomes brittle when it is exposed to superglue or loctite due to the active ingredient cyanoacrylate.

    • @joshrepik
      @joshrepik 18 дней назад +21

      I think it’s a combination of the two. The added rigidity from the super glue, and the perfect line of 90° angles at the stress point. The handle couldn’t flex, and where it couldn’t flex was a straight line where a light scoring would snap that poly

  • @jackturner3803
    @jackturner3803 21 день назад +143

    16:14 partially correct. The flexibility shouldn’t affect its ability to cut much, as steel swords also flex quite a lot. The thickness of the blade is part of the reason it doesn’t cut clean, but the main reason is the steep bevel. A bevel like that can’t get particularly sharp, and it’s a rough transition from the edge of the blade to the spine, massively reducing its cutting effectiveness

    This may be waaayyyy too much work, but there has to be a way to bend the light at the beveled planes so that the light hitting them is transferred through the opposing plane at the correct angle. I'm assuming it would involve changing grain structure at the edge through some sort of heat/pressure treating at edge and end up sacrificing a lot of durability where you want it most, making super precise convex/concave bevels, or a combination of the two. You might even be able to use a mirrored flexible adhesive to create a prism out of the edge (if such an adhesive exists). Either way it would make a great showpiece, but likely wouldn't be functional.

    I’m not normally one to critique, but since you mentioned you weren’t familiar with bandsaws, I thought I might chime in. I noticed that at about 4:33 you made a small cut which allowed the piece to release, as the longer cut was already finished. It’s generally (when possible) best practice to make your longest cut last so that you’re backing out along the blade as little as possible. This lowers your chance of binding the band, which can injure you and damage your equipment and material. You can also make relief cuts into the middle of long spans, like along your (katana) blade, so that you can more easily adjust or take breaks.
    Hopefully this is helpful, and sorry for the long comment, especially if it’s not. Really good work and really cool video-thank you for making it!

    Another reason of why the sword was fragile at the handle is because of the sudden change of shape from handle to blade :
    This is called stress concentration, and it occurs where there is a sudden change in geometry or dimensions of a material, which causes an increased concentration of stress in that specific area
    Additionnaly, one of the reasons of why it did a poor cut on a watermelon could be due to technique, and the thickness of the blade. Swords are purposefully flexible, maybe not as much as yours but this is in order for steel to be able to go back to its original shape, and not just bend when an amount of force is applied.
    Maybe you can try but cutting and not swinging it like a bat, for exemple when you cut vegetables with a knife, you don't just chop it, but you also do a slicing motion, though this is an idea as I have no experience in using a sword, and only know the very small basics of material resistance, and I hope it helps !

    The sledgehammer test breaking the sawhorses was unintentionally so funny. You praised the polycarb for how little damage it took when the sawhorses took almost all of the impact (evidence - they broke). The base has to be stable and in-compressible otherwise you're just passing the force through to the object at the end of the chain. If you're going to use wood at least make them stumps.
    Also for the bandsaw, you should extend the base to support the weight of the thing you're cutting as the bouncing changes the angle the saw meets your piece.

      Try this again but using stumps or rock as your base and you'll see the difference. There will be more bending, potentially shattering as seen in the handle due to flex angles, the sledge hammer will be pushed back with far more force, etc.
      This is basic high school physics. It's why you want your car to crumple in a crash, to absorb the force that would otherwise go through your body. The sawhorses were the crumple zone, and airbags.

    When sanding or grinding, go the whole length of the sword, it will give you better contrast and easier control while you do it. I’ve made several kitchen knives no katanas though. Good luck.

    This version is more of a sharp club than a sword, it didn't so much slice or cut as dent and smash, and shortening it actually did you some favors in terms of being able to maintain edge alignment. I'm really glad you dulled the handle before trying the harder objects! It's still a devastating weapon, capable of shattering bone and crushing muscle tissue and cartilage into useless pulp. Honestly just as terrifying as a clean cut in its own way.
    Bottom line, It's sick af. I definitely think you should finish v1 and make it ultrasharp- a translucent sword is still dope!

      @@GPS08 Haha, yeah, basically. Although I think an axe would still be sharper than this was.

    The first one was way cooler honestly.
    It'd probably cut far better too; this one was more like smashing objects.

    I think the handle issue might be the sharp corner. don't forget stress raisers! a smooth curve to reduce the width to the handle size is better than a sharp internal corner!
