Fun fact : the same instrument has two different names depending on its purpose. It's called a bistoury for surgeries and a scalpel when used in labs to dissect. It's also called a lancet when double edged
A mirror finish on a blade doesn’t mean it is necessarily Sharper. The quality apex of the bevel, the angle of the the edge, and the blade geometry/thinness is what makes a knife sharp or not.
The problems with most (but definitely not all) machined edges on mass produced knives is there's typically no decent method of quenching so many blades while they're being machined so the heat can cause the edge to soften more than necessary. It's why any professional blacksmith will tell you if you plan on using a belt sander to put a bevel on a blade quench it with water as often as you can to prevent the temper from being weakened by the heat produced by the friction of sandpaper on metal. It's why despite the sometimes massive price gap buying hand made kitchen knives is always the superior way to go and you help support small business in addition to getting beautiful quality knives. I'd rather pay 200 for 2 or 3 knives that will hold an edge than 50 for 20 knives that go dull in a week
You know they use coolant when grinding the edge right? Unless it's a really cheap knife, it's unlikely they messed up the heat treatment during grinding. Higher end knives generally use steel that can be heat treated to a higher hardness while still being tough. Although better steel will keep a sharper edge for longer, a correctly sharpened and deburred knife blade will still keep an edge for a pretty long time, even for relatively cheap knives. With proper care, you can keep a cheap victorinox knife for years before even considering buying a new one.
@@MrPolluxxxx read your own comment then read mine. You're referring to HIGHER END knives. I specifically referred to cheap mass produced knives. The point of mass production is provide as much of a product as possible for as cheap as possible with no regards to quality 🤡
@weedconesuer reread my comment. I was saying that even though higher end knives do have an advantage in edge retention, a relatively inexpensive knife that is well cared for won't need to be sharpened very often.
Define sharpest? At cutting paper? At cutting meat? Wood? Rope? Because different edge angles, grits, steels, all make a difference. My kitchen knives are at a much steeper angle than my edc folders. Mirror edge doesn’t translate to “sharper” for certain tasks.
Only sharpen your knives after buying them if you either know how to with a whetstone, or plan on sharpening them constantly (if you don’t have expensive knives with good steel) I bought an expensive knife sharpener that was much more efficient than my manual pull through one. The cost of the sharpener was lower than a new knife set that matches my kitchen. Unfortunately, my purpose was to restore my old knife set….which it did tremendously. However, because of how sharp they are now, they dull MUCH more quickly… This is fine if you’re a professional chef, or somebody that knows how to get the right angle with a whetstone. But for 95% of consumers, the sharpness that the manufacturer ships their knives with is sharpened to be ‘sharp enough’ to prevent the need to constantly need to sharpen them. Most people do not have expensive steel, so edge retention is not something that they will be buying. Telling somebody to sharpen a knife that likely has poor edge retention is setting them up for an unending cycle of sharpening.
Let's not ignore the important other factor, edge geometry. Thin edges will have a huge advantage over thicker in cutting ability which is the main reason a razor is sharper than say a kitchen knife and a kitchen knife sharper than say a bushcraft knife and so on. Your comparing apples and oranges here regardless of how well "sharpened" it is. Almost always the thinner blade will cut paper better. Try cutting a vegetable with it though.
Bud, this has nothing to do with one being better. Obviously they’re both machine sharpened, probably via grinding wheels by robots hence the perfectly parallel grind lines on both. The difference is the kitchen knife’s bevel is sharpened somewhere in the neighborhood of 15°-17°, the exacto or “scalpell has a WAY WAY WAY taller bevel so they can bring the angle of the bevel down even further to say 12°, then the edge is polished to some extent. That’s it. The scalpel gets the benefit of having WAY lower edge geometry on the polished micro bevel which is what you’re seeing, then that cut transitioning to another narrow angled secondary bevel which gives the knife narrowness and it gets to make the cut over a longer surface as opposed to the kitchen knife.
I made a 90 degree with 1018 steel just as sharp as that scaple. How, with a grider used for machining flat surfaces. I am more batshit crazy than German machinist and I stood over that grinder for days and hours to make a retangular block of 1018 perfectly square. That block was mirror polished from that grind wheel and the edges were so damn sharp!
Those aren't cheap 'machine lines' That's the scratch pattern. Every knife has that unless you polish the edge, which is totally unnecessary for a kitchen knife
It looks like an album for a type of hip pop song or ncs or tobu yes they are old youtube channels with almost no new songs but they made my childhood and i heard their songs on old roblox games in the past hmm i miss 2017 so much
I would be more curious to see an actual scalpel and not a hobby knife. Usually scalpels are sharper than hobby knives but made of a worse steel as they dont need to be sharpened and instead the blades are replaced.
Xacto knifes are not scalpels but they are more brittle than kitchen knifes because of how sharp they were. I once had my blades changed every one or two weeks because they go blunt so easily. They're kinda evil though since they gave me a large cut that bled for hours.
More tests! - ua-cam.com/video/u94cIxshbfg/v-deo.html
Check a wasp stinger🙂🙂🙂
you ah briish
How stupid is it to look at the knife under a microscope, just test the damn thing in the real world and just cut something.
I wonder what the blade of an obsidian tipped scalpel looks like.
Sounds expensive but I'm intrigued
@@AlmostLakai94 Probably so. Those things cut on the cellular level so I'm not surprised if they're not cheap.
@@aegis6485 technically all sharp edges cut at a molecular level, they just dull out quick
I didn’t even know those existed but now I’m curious
@@hipie379 I don't think they're widely used. I think for the most precise, important surgeries is where they see usage
That's a utility razor, not a scalpel
It’s a exacto knife 😭
@@djjathegod_03 X-Acto knives are utility razors

Guys lets all collectively agree that its sharp and it cuts☠️
@@aurvea1199 Yes
Remember guys, size doesn't matter
AYOOOO?
That's what she did not say
Just because the tool works sometimes doesn’t mean it works all the time
I mean I’d rather get attacked by somebody holding a scalpel tbh
And some stuff like axes have broad edges for durability.
Fun fact : the same instrument has two different names depending on its purpose.

Just wait until bro learns about obsidian scalpel
Man i love these types of videos!
When he said 'Scalpel' I screamed at my screen, 'THAT’S AN EXACTO KNIFE!'-
Obsidian: "my time has come...., you must continue your journey... without ME.."
Not a scalpel wouldn't use that for surgery that is a exacto knife used for crafts
i feel like i watched 10:00:00 HOURS of a short
You can just type 10 hours instead of 10;00;00 hours, it's like saying 10 hours hours

To call a knife with a massive roll in the bevel a "clean edge?"
Yes, he's such a valuable resource...
Find a chef and compare his hand sharpening to a cheap store knife!

Thise lines on the forst blade are microserrations, they can help actually.
the scalpul looks fucking gorgeous zoomed in
The first one looks like a bar code

The scalpel is used in surgeries, the thing the scalpel is EXTREMELY known for
We, the galactic republic, have won the war
Just realized how bad washing dishes by hand could've been if i ever sharpened my knives
Then there’s obsidian.
“It’s just like butar”
The sharpest knife is the obsidian scalpel. It blade has a wigh of 15 nanometers wigh and literally can cut cells.
Those aren't cheap 'machine lines' That's the scratch pattern. Every knife has that unless you polish the edge, which is totally unnecessary for a kitchen knife
U should do an obsidian staple.
Cool video!
What kind of camera setup you use?
The circumcision tool better be sharp, yo... 😅
Sorry to say but that looks more like a hobby knife then a scalpel but the video is still great at showing the difference on the sharp knifes
Try an obsidian blade lol. Those things are SHARP like just doing a light poke could penetrate someone. No pun intended.
Those scaps are wild
I WAS EXPECTING PEDRO PEDRO PEDRO!
Omg i scanned the knife blade it looked like a barcode IT CAME UP FOR ORGANIC BANANAS
Cap
Scalpels are for making precise cuts meaning they are EXTREMELY sharp
Very cool!

That’s not a scalpel that’s an exacto knife. Artists use it to cut out paper in a precise area
Thanks please get a before and after use of the knives video too if they get dull

Also known as an *exacto blade
If you like brand names.
Very cool.
I was like whatttt when man said scaple
His face is the most innocent one i have ever seen.. ❤
I am watching this video while holding a scalpel 😎
The scalpel lines look like lights.....hmmm I'm getting an idea imma make that into a Forrest (Drawing)
Its not "the sharpest knife in the word".
Razors are sharper than scalpels
The last zoomed shot looked like several lines of code
“Then I zoomed in further on the kitchen knife, I could see the individual bacteria moving about”
A British man with a knife? GET HIM!!!
That is not a scalpel its a exacto knife for arts and crafts but still sharp cuz it’s a Razor
Smooth like butter criminal under cover
Bro you could not force me to cut paper with a scalpel with my finger millimeters away 💀
the x-acto knife under the microscope looks like a broken screen effect
Obsidian knife left the chat
That's an exacto knife, not a scalpel
The word mirror finish: people actually used mirrors/glass to sharpen to make it finest sharp.
It's done at the end of sharpening process.
Well scalpels are used for surgery so it makes sense
dude got arrested by the bobbies for this video
he didn't have a knife license
Do Brits call utility knives “scalpels” or does this guy just not know what it is? 🤔
bro called an exacto knife a SCALPEL
Lol testing the kitchen knife on paper for a fraction of a second vs the scalpel for multiple seconds
Use a ceramic plate shard
Very cool 👍
mmm yes because surgeons use X-Acto knives

My standard for my utility pocket knife if I can’t shave with it, it ain’t sharp enough
That is just an Xacto knife or similar off-brand utility/hobby knife of the same kind. That is not a scalpel.
the tip of the knife should be black and sharp
Bruh that’s a hobby knife not a scalpel
Scalpole are super high quality blades for clean cut in skin so it doesnt make alot of damage on the skin
I would be more curious to see an actual scalpel and not a hobby knife. Usually scalpels are sharper than hobby knives but made of a worse steel as they dont need to be sharpened and instead the blades are replaced.
That's not a scalpel thats an exacto knife made for crafting.
obsidion is 500 to 1000 times sharper than the sharpest steel blade which makes my head hurt
Scalpels have a curved blade..That knife would be too difficult to precisely slice soft tissue and skin.
Dutch Van Der Linde is that you?
Xzacto very different from a scapula
that is not a scalpel...
That "razor" seems pretty dull imo
Nothings sharper than water if you use it right
It’s almost as if exacto-knives are meant to be sharper and better at cutting paper
A scalpel must be incredibly sharp as to not cause additional trauma.
