Sharpest Scalpel Blade In The Operating Room⁉️
HTML-код
- Опубликовано: 8 фев 2025
- How Sharp Are Surgical Scalpels: From ancient obsidian blades to modern ceramic-coated instruments, surgical scalpels remain the cornerstone of medical precision. Today's scalpels combine centuries of innovation with cutting-edge materials science, featuring interchangeable blades that revolutionized surgical practice since Morgan Parker's 1915 design.
Did you know? Modern surgical blades come in specialized shapes for different procedures - from the versatile #15 blade for delicate work to the larger #10 for major incisions. Each blade is precisely engineered with medical-grade steel or advanced ceramics, ensuring unparalleled sharpness and sterility.
The most common setup pairs a #3 handle with various blades, allowing surgeons to maintain perfect control while making incisions as precise as 0.1mm. Some contemporary scalpels even incorporate zirconium coatings and nanostructured materials for enhanced performance.
Key features of modern surgical scalpels:
Disposable blades for optimal sterility
Ergonomic handles reducing surgeon fatigue
High-carbon stainless steel construction
Various blade profiles for specialized procedures
Precision-engineered cutting edges
Whether performing delicate microsurgery or major operations, these essential tools continue evolving to meet healthcare's advancing needs.

In fact, scalpels come in very different quality. I have come across replacement nibs made in Japan, and they were razor sharp.Now for technical purposes I have nibs from Pakistan, I think, and they are of terrible quality - I have to sharpen them by hand and even correct the shape of some.
completely true. limit to utility of progessively "sharper" blade. balance of sharp vs control in operating room. thanks for sharing
@@BoneDoctor_RUclipsdidn't ask
My transistor radio comes from far away
100% true. I work for a company that makes scalpel blades in the US. They are sharp, but my razor blades I shave with are sharper. With some work,I can sharpen my pocket knife to be roughly as sharp as the scalpels with a basic Worksharp precision adjust sharpener.
generally I wouldn't buy anything but ninja stars from Pakistan.. (though I do believe there will be good bladesmiths out there in those mountains..) I've seen too much junk come from there.. it might be on principle for them lol.. but..
Obsidian is the sharpest material on earth cutting molecules in half
I've seen some videos in which obsidian scalpel was used
Nah, obsidian blade is several molecules thick, if a molecule were the size of a pea then an obsidian blade would be a sledgehammer
@@last_fanboy_of_golb I think it might be used in cosmetic plastic surgeries where they often go for less scaring
thanks for sharing. limit to benefit of "sharper" in operating room
Spreading misinformation is the most effiecent way of showing your childishness. No, the sharpest object we know of is a tungstem needle, with an atom this edge. It is possible becouse of the hardness of tungsten.
Looking at a cut done with a scalpel under a microscope is like looking at a job done with a chainsaw.
Very cool perspective. Thanks for sharing.
It actually prompts healing better like that, sort of like how a zipper seals together, it promotes quicker healing because there is more contact area.
@@TylerDobbs-g5uLast I checked, the cleaner a cut is, the faster it will heal and with less scarring.
@@TylerDobbs-g5usaw this little factoid about a british WW2 knife made to be extremely sharp so that the wounds would heal slower (personally I thought it was just the fact that it was used to stab more than slash that caused that reputation)
What about obsidian tipped scalpels?
The true sharpest thing in the hospital is: the bill
ouch!!!! can cut to the soul.
obsidian isnt used because its too dangerous and brittle, will break into tiny fragments if used on a person, tiny pieces would burrow into your skin or empitdermal
Umm obsidian scalpels are used by some surgeons for specialty surgeries.
www.main.nc.us/sams/obsidian.html#:~:text=The%20American%20Medical%20Association%20has,being%20used%20in%20surgery%20today.
And yet theyre still used all time🤡 against skin never seen one break
@bpitts31 im sure you didnt learn anything, but thin obsidian dude, the sharpest one is a thin obsidian, even the gentle touch will break it
@@bpitts31????
@@redtalonxs yes, thin obsidian will break, but it's still used for a reason, I use obsidian to cut everyday and haven't had an issue
A patient cured is a customer lost.
Surgeons dont want super sharp scalpels. If its too sharp it prolongs the healing process.
That I did not know and I’m a scrub tech. I’ve mainly seen scalpel used for very thin skin incisions and bovie the rest of the way. I have seen some ortho guys like a “deep” knife though. The sharpest blade I’ve seen is diamond and that’s used for eye surgeries.
How does a sharper blade equal longer healing time? In every single instance I've ever seen, the sharper the blade, the better the cut, and the quicker it heals.
This is false. The sharper, the shorter the healing time, as seen with obsidian blades
This is a lie...im a plastic surgeon and the sharper the blade, the better the healing and lesser scarring.
Actually this is a complete lie.
People in operations would love to have the sharpest knife possible because any dullness in the blade leads to sells been completely torn apart.
Well with a shuffle knife must cells are torn.
The only reason we don’t use the sharpest blade ~~ obsidian~~ It’s not because it’s too short but because it’s too brutal and we don’t want to leave any particles inside the patient
Too sharp and it cuts without any feel, which can cause other problems when it becomes difficult to tell whether the blade is making contact or not
Absolutely true, and the perfect explanation of why sharper is not always better. Control and precision are keys in most operating room procedures. Thanks for taking the time to share.
Obsidian blades are considered the sharpest knifes in the world.They are made from volcanic glass and can be microscopic in thickness
Explanation
*Obsidian*
Obsidian is a hard,brittle amorphous material that fractures with sharp edges.
*Obsidian blades*
Obsidian blades are made by flaking a long,thin silver from a core of obsidian.
*Sharpness*
Obsidian blades are 10 times sharper than a razor blade.
*Use*
Obsidian blades have been used in delicate medical procedures,but are not currently licensed for use on humans
In the kitchen,Chefs often refer to high-end japanese knives as sharp knives.These knives are made with High-Quality steels and are designed for precision.
They have our diamond scalpels for particular eye surgeries. Very, very cool stuff. I mainly scrubbed CT as a scrub tech so we only used a knife for incision or cutting plaque or calcifications off of valve leaflets/ cusps.
Excellent information. Appreciate you taking the time to share your experience.
Obsidian scalpels are pointless because sharp wounds take longer to heal
Obsidian is sharp. It creates cleaner cuts and smaller wounds, allowing quicker recovery. Next time, read a book.
smooth brained idea
Surgeons have to worry about nerves when cutting, hence why it is designed the way it is.
True, damage to healthy soft tissue always a consideration
@BoneDoctor_RUclips Yeah hence why my right pettla is permanently damaged
You actually DON'T want something to be super duper molecule-splitting sharp. Because really sharp edges will separate material at a TOUCH and you basically have no control.
completely agree! Thanks for sharing.
I don’t think the purchasing department is at hospitals care beyond cost per unit
This is a great channel. Thank you for your content.
It's more important to cut in the right place than cutting the easyest
Very true. Precision and control are most important by far (and the person making the incision). Thanks for sharing 🙏
Suddenly, everyone is a professional tiktok educated scientist and blade master.
My favorite part is when he tells us the sharpest blade out there.
Knew a surgeon who only used obsidian scalpels .
its not a lie its just more power full than people expected.
its can cut thur time and space
time and space?
Scalpels are that sharp because it gives a clean enough cut but also has some jaggedness to it which helps heal faster. The straighter and cleaner the cut the longer it takes to heal.
Thanks for sharing.
False. Jagged blades make messy cuts, which take longer to heal. Next time, test it on yourself before sharing.
Dude you sound like one of those YT shorts advertisement scammers with the music and tone.
Sorry about that. Not selling anything or scamming anything here. Thanks for taking the time will fire the editor.
@ not trying to be a dick but I did almost scroll out of instinct from it, other than that good video!
Histology microtome blades are the sharpest to be able to cut tissues at 1 microm
yes, very sharp! Thanks for sharing.
@@BoneDoctor_RUclips I'm a Histologist
Another thing is shatter risk. Materials that get sharper like harder metals and ceramics have a small risk that part of their blade will chip off. This is fine for (say) a hunting knife but not when the chiped off metal will stay inside the body. So softer metals which bend insted of break are used deliberately.
The cleaner the cut, the longer it takes to heal. Medical scalpels are usually a little jagged on purpose if you look at them under a microscope. Again, just makes the healing process easier.
Good lord, this comment section is stupid. Ever heard the phrase "a sharp knife is a safe knife?"
Clean cuts heal quicker than messy ones. Sharp knives don't tear out as much material as jagged or serrated ones.
At first i thought he said "Its alive"
my bad. Thanks for taking the time.
I doubt that, my mom brought a scalpel from the hospital once, that thing could cut anything near it 😂
It was the sharpest object I've ever seen, and I really like knifes!
Had a knife being laser sharped and it wasn't even close to the scalpel!
sharper than some knives, but don't stay sharp for long - typically. be safe!
@@BoneDoctor_RUclips yes!
It loses its sharpness so fast!
It was a disposable one.
Obsidian blades would be the sharpest blades but using them in medicine would be a really bad idea since they can break very easily since its a really weak material, imagine leaving an obsidian shard inside a patient
Even bringing one to an operating room would be the fastest lawsuit
Thanks for sharing.
The sharpest thing that cuts way too deep is our tounge.
preach!
Every type of blade has its own purpose
agreed! Thanks for sharing.
You have to have enough material resistance in order to control, to feel the material you are cutting.
True. Thanks for taking the time to share.
Ignorance, there's tungsten scalpels that are so sharp U cannot feel it cutting.......
Dude he’s literally a doctor?
there are sharper blades in medicine, but scalpels used in most surgical procedures are not the sharpest. Thanks for sharing.
Obsidian. Down to a single molecule
I always thought they wouldn't make them too sharp due to their tensile strength. Unlike tungsten which has high tensile strength, but would be much more costly to produce (scalpel blades are replaced after use).
My mistake tungsten max tensile and yield are much closer than 304 ss, tungsten can be more prone to crack s vs ss which will deformation before cracking
all great info. Thanks for sharing.
Tungsten is brittle. Unless alloyed, which is expensive, it has a tendency to shatter.
And that's why the referenceword is "razorsharp", and not "scalpellsharp"
great point! Thanks for sharing.
Control comes from the person operating it.
true and the right instruments help. Thanks for sharing.
Scalpels are good for downwards pressure, while obsidian blades are good for cutting sideways pressure
Thanks for sharing. minimal experience w/ obsidian blades
@BoneDoctor_RUclips You know what you're right. I don't know much. but some people don't know this fact already. Appreciate your time
My wrists are scared
how's the wrist doing?
@ bad
I don’t get what he means by control please elaborate😭
Being able to feel, predict and control depth of incision based on pressure applied - predictable, repeatable and controlled. Thanks for taking the time 🙏
Holding it like a pencil...
So like an artist they have more precision
@@Chiglimiglywhat??
Scalpels shouldn't be too sharp. They are used to cut what you need to cut. If they are too sharp, you're running the risk of accidentally cutting something you shouldn't have. They are sharp enough to do what you need them to do, and no more.
Hunting knives are used to hack through muscle, cartilage, wood, etc. No control needed, but they need to be sharp for what they are used for since they aren't built to only cut through soft tissue. They are made strong and sharp. Like, you won't need a machete to do heart surgery, the same way you won't need a scalpel to build a wood hut.
completely agree! control and precision are priority in OR. Thanks for sharing.
Literal skill issue. Sharper knives make cleaner cuts. Cleaner cuts heal quicker.
The skin is the largest organ in the body and your skin is pretty tuff. It takes effort to cut the skin. You’re going to cut through a lot of smaller nerves, oh well it can’t grow back. The disposable ones are the best. They also come in many shapes and sizes
agree, balance between sharpness + control. thanks for sharing
Obsidian blade ❤
popular answer. thanks for sharing.
An actual sharpest blade was designed by the Russians specifically to function as a blade that is capable of jumping air into a wound like puncturing a compressed air cartridge, and then all of the air is injected through the blade. Not a small tube, but the plate itself is basically a semi hollow structure.
wow, thanks for sharing. going to check it out
Still doesn't mean it's sharp.
Either obsidian or Dikfor is the sharpest
Thanks for sharing.
Id say that the most precise and sharp blade in medicine is the gama knife
You want to feel like cutting something so you hand can figure what the blade even touching
scalpels ARE the sharpest blades in context
they are the only blade used once. You compare a knife after normal wear to a scalpel after normal wear, and the scalpel will always be sharper
Recently my fistula removed I'm feeling better now
Ouch! Hope all healed and going well.
Although brittle, obsidian can shatter or be sharpened to atom thick edge
can be made to be very sharp. Thanks for sharing.
Obsidian ones are !
The lack of total sharpness helps wounds heal faster. Jagged torn skin clings to other jagged torn skin much better than clean cut skin.
No, it doesn't. Dull, jagged blades actually dig some material out from the wound, making it larger and requiring much more time to heal compared to a clean cut. It's one of the reasons why papercuts hurt more than regular ones.
I didn’t know that thank you!
Thanks for taking the time 🙏
Can confirm, picked up some scalpels for NSSI reasons and they're dull asf compared to doubled edged razors. To their merit though crazy controllable!
True. Thanks for taking the time.
What's the physical definition of sharpness?
excellent question. defer to knife specialist here on app
Easy one is meant to be used on dozens of dead things the other is made to be used on one living things
I've been using and indian made surgical scalpel handle with high quality blades for my diy projects,
You can't get misaligned with this, everything gets cut like butter
Obsidian scalpels are but they can be too damaging in some cases cutting you cells in half increasing recovery time
thanks for sharing. not practical for most OR procedures
You're right, but for the wrong reasons. Cleaner cuts heal faster, but obsidian is brittle and has a tendency to shatter. Especially inside of your patient. No good.
OBSIDIAN FLAKES, are the sharpest and theu also cut between the cells therefore making a smoother scar.
🤔 Obsidian would make a better scalpal for a surgeon, allowing a cleaner cut with the patient healing more quickly from it, too.
better? can make predictable control more difficult. excellent for some procedures, not best for all. Thanks for sharing.
But obsidian is fragile. If it breaks inside your patient, you're in big trouble.
Not really a blade but there is a tungsten needle with the tip width of a single atom, which is the sharpest thing in history
i still have the scar i cut myself with a surgical knife while fixing a tv
definitely sharp enough to do damage. Thanks for sharing. be safe!
Damn lemme get one so I can use it on myself
not recommended!
The reason why it's not extremely sharp is so that the cuts made would heal faster
and optimize predictable control, minimize risk of harm to unintended surrounding tissues. Thanks for sharing.
How so? Cleaner cuts heal faster.
been cut by scalpels and knifes. Fiskars garden knife will cut you without you noticing the pressure, scalpels will make you feel every cut.
Ouch! Hope all healed and going well.
The glass knife of an ultramicrotome is the sharpest blade i know of.
Did anyone ask?
@@chinchuck4090 no, but it dose not change the fact its one of the sharpest blades you can make. Its used to to slice
@@lbochtler out of curiosity are thete any videos around showing these procedures and such? Cause i think it would be realy cool to see what happens and how
@@loquenlucas9060 there are, but they are usually old, i saw one from Porter Blum some time ago. Could not find it anymore though. Since i work at the museum of electron microscopy in Nuremberg Germany, we do have videos from the manufacturers that show the process, but cant publish them due to copyright. We do intend to on making a video series about the processes of electron microscopy preparation, but currently we lack the time due to understaffing.
You can try and look up TEM sample preparation videos, it should show you at least some of the processes.
Thanks for sharing.
Either obsidian or I hear they use lava glass
Obsidian is the sharpest material
So is water when under massive pressure concentrated into small area
also, that water is mixed with microabrasives
and obsidian is fragile
many sharper options, but sharper not always better in operating room. thanks for sharing
very true. not practical for most surgical procedures.
You wouldn’t use a chainsaw to operate, a scalpel is very thin, cheap, easy to produce, obsidian and lasers are sharper I believe, much more expensive and or harder to mass produce like scalpels
True. Thanks for taking the time to share.
And yet I use one for warhammer
Dull scalpels are better for healing
but not too dull??
No, they aren't. Messy wounds leave scars, while clean ones don't. I would know because I've been cut with knives time and time again, yet they all heal like they were never there. But I cut my hand open on a rock and I still have a scar on it to this day.
Context: The sharper the scalpel, the slower the wound heals.
No, sharper equals less trauma, therefore better healing. Please stop spreading misinformation
i stg if he says obsidian
Obsidian
can be made to be very sharp. Thanks for sharing.
Aren't the more delicate blades made of molecule thick obsidian?
So if it's too sharp you can't control the cut?
could be tougher to control - there is a limit to "how sharp" benefit for most surgical procedures.
Isn’t a lot of this done with a co2 laser?
My victims prefer a #11.
scary thing to hear. Thanks for sharing.
Obsidian is the sharpest they even started using it in surgeries if you were to compare the cuts under underneath a microscope, you’d see that the scalpel looks like a somebody chopped something with an ax wow obsidian has a smooth clean cut
I've known this since I was a young kid and I first got in the knives.I had buck knives that was sharper than any scalpel nowadays I have knives.That would cut a scalpel in half 😂
very true. be safe. thanks for sharing
I don’t think many people actually think that scalpels are the sharpest in the word 🙄
excellent - Thanks for sharing.
@@BoneDoctor_RUclips By the way, you really don't have to respond to every comment. Especially negative ones, it might not turn out well in the long run
its not that, its actually to not cause as much harm to the tissue
Boy, do I know that since a doctor saw my cut thumb. My dad's knives could spit hair several times over, making spit ends look thick.
Thanks for sharing.
Double edge razors are scary sharp
It's not a lie, you are not a specialist in sharpness
Thanks for sharing.
The use of scalpels is getting less and less anyways, since electrosurgery is way safer and more efficient in most cases.
true, but initial skin incision still most often with scalpel. Thanks for sharing.
Obsidian scapels are the sharpest cutting instruments on this planet. Look it up
Thanks for sharing.
My Obsidian Sword 🗡️ Even Cut Dragon's Skin...
sounds sharp
Flint knives are the sharpest blades 😮
obsidian is sharper
Thanks for sharing.
not sharp cause your asleep in operating room hhahaha
Earlier chiruges had blades made of some kind of christal or stone > megasharp!
He said it blade
The sharpest thing in this world is tungsten ultrafine needle which is aprox 1 to 2 atoms thick
more disinforman I worked 33 years in the operating room. we have all types and shapes if scalpels plus special knifes for amputations. When you cut into the eye those are the most precise and sharpest ones.
no "disinformation" here. there are a number of specialty blades used in surgery and the disposable "scalpel" used in most surgeries is not that sharpest. Thanks for sharing.
The sharpest thing is actually a katana but the sharpest thing is also a obsidian shard
Agent 47 would like to disagree with you.
listening...
Water jet cutting is sharper. It will slice through an anvil like it was budder.😅
True. Thanks for taking the time.
@BoneDoctor_RUclips np
Well, you can't control how deep a waterjet slices. It makes a fucking hole in the surface you're cutting your material on.
pretty sure this guy slapped his face on this video and ripped the script off the original too. ive seen this video word for word frame for frame before and this only came out 2 days ago :|
please share. Thanks for taking the time.
@ youtube bots are a plague
The real reason that they’re not actually that sharp is because it’s a lot harder to close a cut that’s extremely clean. The skin doesn’t bind and heal as easily. That’s why scalpels have a jagged, but yet very sharp grind.
Thanks for sharing.
Wrong. Scalpels aren't very sharp to cut down on production costs. They're single use, so you have to make a whole bunch of them.
Dull knives make poor cuts and sometimes remove material. You don't want to remove material. Removed material takes time to grow back.
Pretty sure my 200+ giant mouse ace would win that battle of sharpnesses much less my hunting knives! 😂 fair point though fun fact obsidian scalpels are sharper than hunting knives at the disadvantage of being extremely brittle!
yes, sharper but more brittle and not practical for most surgical incisions. thanks for sharing
oh no its a lie now i cant love my life 💀
Thanks for taking the time. 😅
