I wonder what the blade of an obsidian tipped scalpel looks like.

That's a utility razor, not a scalpel

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

Remember guys, size doesn't matter

And now we wait for some yahoo to say “why didn’t you test the knife on concrete to see which one cuts better?”

Just wait until bro learns about obsidian scalpel

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

I’m so happy people like you are in the community❤️

Man i love these types of videos!

Obsidian has left the internet

Obsidian: "my time has come...., you must continue your journey... without ME.."

When he said 'Scalpel' I screamed at my screen, 'THAT’S AN EXACTO KNIFE!'-

i feel like i watched 10:00:00 HOURS of a short

Find a chef and compare his hand sharpening to a cheap store knife!

Great content!

Now look at a diamond scalpel

Not a scalpel wouldn't use that for surgery that is a exacto knife used for crafts

Certified British knife crime review

Thanks please get a before and after use of the knives video too if they get dull

oh I love using scalpels ... or chiped stone because.... thats just cool :D

My mom always sharpens her kitchen knives to the point where it looks like the second one

The first one looks like a bar code

Very cool!

the scalpul looks fucking gorgeous zoomed in

Kai Shun: "XD i cut everything"

I WAS EXPECTING PEDRO PEDRO PEDRO!

Scalpel? Isn't that just an x-acto?

U should do an obsidian staple.

The circumcision tool better be sharp, yo... 😅

If this is worlds sharpest knife then I am also a Elon musk

MY ANXIETY WHEN THE SCALPEL WENT RIGHT NEXT TO HIS HAND 📈

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!

Damascus Knife: Am i joke to you?

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.

His face is the most innocent one i have ever seen.. ❤

Very cool!!

Then there’s obsidian.

Very cool 👍

“It’s just like butar”

Just realized how bad washing dishes by hand could've been if i ever sharpened my knives

Thise lines on the forst blade are microserrations, they can help actually.

Scalpole are super high quality blades for clean cut in skin so it doesnt make alot of damage on the skin

Cool video! What kind of camera setup you use?

Pretty cool!

Scalpels are for making precise cuts meaning they are EXTREMELY sharp

Try an obsidian blade lol. Those things are SHARP like just doing a light poke could penetrate someone. No pun intended.

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.

That's an exacto knife, not a scalpel

A British man with a knife? GET HIM!!!

The scalpel is used in surgeries, the thing the scalpel is EXTREMELY known for

Very cool

The scalpel lines look like lights.....hmmm I'm getting an idea imma make that into a Forrest (Drawing)

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

The last zoomed shot looked like several lines of code

Very coo-

Smooth like butter criminal under cover

bro called an exacto knife a SCALPEL

“Then I zoomed in further on the kitchen knife, I could see the individual bacteria moving about”

Dang I tried to scan the knife has a qr code

I am watching this video while holding a scalpel 😎

Next Video: Which Knife can cut a Vibranium Sword in half?

Use a ceramic plate shard

Lol testing the kitchen knife on paper for a fraction of a second vs the scalpel for multiple seconds

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.

Razors are sharper than scalpels

Bro you could not force me to cut paper with a scalpel with my finger millimeters away 💀

Its not "the sharpest knife in the word".

Gunz and buttah, baby!!!

the x-acto knife under the microscope looks like a broken screen effect

Please do katana

Can you please do cheap Vs expensive heart Surgery?

That’s not a scalpel that’s an exacto knife. Artists use it to cut out paper in a precise area

Obsidian knife left the chat

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!

Good short

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

Omg i scanned the knife blade it looked like a barcode IT CAME UP FOR ORGANIC BANANAS

I keep snapping scalpel blades cutting thin foam…

Can u try obsidian shards?

mmm yes because surgeons use X-Acto knives

I want one…

Dutch Van Der Linde is that you?

QR code

Very cool! Yam yam 😈

My standard for my utility pocket knife if I can’t shave with it, it ain’t sharp enough

That's an x-acto knife, not a scalpel. A scalpel would be much sharper.

dude got arrested by the bobbies for this video he didn't have a knife license

that's what you call a secondary bevel

That is not a scalpel its a exacto knife for arts and crafts but still sharp cuz it’s a Razor

omg, the scalpel was so close to your finger...

Microscope is what small people use for mouthwash

Xzacto very different from a scapula

Well scalpels are used for surgery so it makes sense

Who would’ve thought a sharp knife is sharp

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.

why does the scalpel edge make me think of code nside an ide when its rly zoomed out

I got the same knife at home and when i was cutting carrots for my sibilings c i was bored i cut my thinger it started to bleed Lol

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
