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.
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.
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
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!
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.
Me personally I'd recommend leaving the kitchen knives be. My brother tried sharpening a knife once and he had made it so rediculsly sharp that he had litterly managed to cut through almost his entire thumb without even noticing whilst trying to cut a potato. He did managed to get it reattached because it was still just barely hanging on but even the bone was a clean cut. We ate that meatloaf with the fried potatoes too. It tasted like what happens to your mouth after u mistake cotton candy for fiber glass insulation (blood)
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.
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
Sharpest knife in the world he said. You do realize there is scalpels that are made of titanium with a black diamond core and edge right ? One of these scalpels cross sections presses on
That scalpel is no joke lol, my friend went for a checkup and a scalpel dropped off the table(unlucky him) It went through his lap like butter then it went from 90° to 30° and make a big wound that he could see his bones.
except not all scalpels are polished like that. so there is a good chance your surgeon is using the breadknife finished scalpel. trust me, they wouldnt know sharp if it cut them. this aint the old times where surgeons checked their tools.
More tests! - ruclips.net/video/u94cIxshbfg/видео.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☠️

Awesome!
I will probably forget this right away but still am so profoundly happy I read this :)
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.
And now we wait for some yahoo to say “why didn’t you test the knife on concrete to see which one cuts better?”
Oh
@royaldragon758he said it

To call a knife with a massive roll in the bevel a "clean edge?"
Yes, he's such a valuable resource...
Man i love these types of videos!
Not a scalpel wouldn't use that for surgery that is a exacto knife used for crafts
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.
oh I love using scalpels ... or chiped stone because.... thats just cool :D
Scalpel? Isn't that just an x-acto?
Yes it is idk why he doesn’t know this…
thats a brand name
@@worthmore2282 no sht, sherlock. A "precision knife" then. A scalpel is something different
Now look at a diamond scalpel
That's an x-acto knife, not a scalpel. A scalpel would be much sharper.
Thanks please get a before and after use of the knives video too if they get dull
That’s not a scalpel that’s an exacto knife. Artists use it to cut out paper in a precise area
Try an obsidian blade lol. Those things are SHARP like just doing a light poke could penetrate someone. No pun intended.
If this is worlds sharpest knife then I am also a Elon musk
Just realized how bad washing dishes by hand could've been if i ever sharpened my knives
Then there’s obsidian.
Razors are sharper than scalpels
Do Brits call utility knives “scalpels” or does this guy just not know what it is? 🤔
The scalpel is used in surgeries, the thing the scalpel is EXTREMELY known for
We, the galactic republic, have won the war
Omg i scanned the knife blade it looked like a barcode IT CAME UP FOR ORGANIC BANANAS
Cap
The first one looks like a bar code

“It’s just like butar”

the scalpul looks fucking gorgeous zoomed in
Cool video!
What kind of camera setup you use?
Great content!
Scalpels have a curved blade..That knife would be too difficult to precisely slice soft tissue and skin.
the x-acto knife under the microscope looks like a broken screen effect
Microscope is what small people use for mouthwash

That kitchen knife did not cut well at all
bro called an exacto knife a SCALPEL
That "razor" seems pretty dull imo
That is just an Xacto knife or similar off-brand utility/hobby knife of the same kind. That is not a scalpel.
Those scaps are wild
His face is the most innocent one i have ever seen.. ❤
mmm yes because surgeons use X-Acto knives
The circumcision tool better be sharp, yo... 😅
Nothings sharper than water if you use it right
obsidion is 500 to 1000 times sharper than the sharpest steel blade which makes my head hurt
Obsidian knife left the chat
A scalpel must be incredibly sharp as to not cause additional trauma.
Bro you could not force me to cut paper with a scalpel with my finger millimeters away 💀
the tip of the knife should be black and sharp
Use a ceramic plate shard
Lol testing the kitchen knife on paper for a fraction of a second vs the scalpel for multiple seconds

Its not "the sharpest knife in the word".
That's not a scalpel thats an exacto knife made for crafting.

Once I got the blunt side of a butter knife razor sharp by using an angle grinder and a sharpening stone...it takes a while, but anything is possible!
That's an X-ACTO knife, not a scalpel.
Then what is a scalpel? Bc to me that looks like a scalpel, not what ever an “X-acto” knife is.
My standard for my utility pocket knife if I can’t shave with it, it ain’t sharp enough

Sorry, I saw a UK man with a knife and instantly thought memes.
Cool video, educational. 👍

Ahh, yes comparing medical equipment to basic kitchen tools 😌
That is NOT a scalpel.
An exacto knife is nowhere near as sharp as a scalpel. I would be very interested in seeing an actual scalpel under a microscope.
Where'd you get that kitchen knife? The Dollar Tree? LOL
Exacto knife, not a scalpel
This must be American, bc I have no idea what an exacto knife is
That’s an exacto knife, not a scalpel
British moment
Who would’ve thought a sharp knife is sharp
I can seem to find if the knife is to the left or to the right
Its not a scalpel, its an exacto blade🤦♂️
adn with damascus
Its not a scalpel its a hobby knife
Why does the kitchen knife look so fake
Dang I tried to scan the knife has a qr code
