- We made the world's sharpest petrified wood knife with our 60,000 PSI waterjet and some other goofy methods. It turned out quite awlraight.
Here's the obsidian knife Video

Go to a local hospital, and ask them about the glass blades used for microtome dissection. Those are the super-sharp blades people often think about with finer than a scalpel. Using the the waterjet to sharpen either soda-lime or borosilicate glass would be an interesting investigation. (The former is everyday window glass, the latter is heat resistant extra tough - like name brand "Pyrex" used to be made with the stuff.) Neither should have the occlusions and irregularities of natural materials like petrified wood.
"do you have scruffy ba-" that cut was fucking hilarious 😂
If I'm not wrong, obsidian only makes an insane edge when its knapped not ground. harder, consistent materials would probably work better for a cut/ground edge.
You guys need to purchase a Lansky diamond sharpening system. It would put a razor edge on anything softer than diamonds and it uses water for sharpening
Love the effort and the results. You guys deliver silly fun on Saturday mornings! 😄
What effort just playing around with the water jet.
I just love experiments! You never know what you are going to get. It is always great fun!!! ☺️
5:57 That actually got me lmao
Ok where is Dan? I am getting worried. Mitchell has been absent lately too.
It seems you haven't watched this channel lately, they moved on to their own channel, so I doubt they will be appearing on this channel any time soon or frequently at all.
@@carolinacoreas7716 Well I havent been finishing the videos lately without Mitchell, did they address this? What is new channel?
@@artonline01 I believe they are now on their old car channel? They posted the news of their moving on like 2-3 months ago? Don't remember exactly when. The didn't clarify if they permanently left this channel, but they are still on TH-cam.
Gotta love the unintentional serrated knife builds
kiwami been really quiet since this came out
Thanks again for the custom knife blank!
Would make a awesome handle material though !
They are slowly turning into Dan and Mitchell
This is what we thought sticks where when we were kids lol
For a fair test, you need to make an obsidian knife with the same technique. Obsidian will definitely reign supreme then.
Did you see the one they did a while back that has a link shown at 8:37 in this video? Maybe you did and you want them to do a new one with this video's techniques.
@@bigfan6016 yes, that is literally what they want
@@bigfan6016 aye, that's what I meant.
0:36 🤣🤣 I love the randomness of this inclusion
We want the original guys back!
7:44 just trying to boost their self esteem
Damn this channel is doing numbers with the new guys
It wouldn’t matter because of the way you were sharpening it was at a 50 degree angle or more
Now make a knife out of regular wood
"Oh yea! Razor Sharp!" Literally doesn't shave off a single whisker. Lol
THIS IS ART!!!
Just looked this up, fun fact just to let you guys know, steel is 4.0 on the moh's scale of hardness and titanium is a 6.0
thhats a massive knife. way above average.
One more knife project, and you'll have to rename this the Prison Shank Channel ... or at least team up with Kiwami Japan and do a collab.
"I really don't like cheese that much"
YOU MONSTER! How could you!
Ah yes. A knife that can smooth the whetstone.
Perfect. 👌
OP spotlight: Fistbumps a wasp, "What up thug."
Nothing like sharpening a stone knife on a softer stone
The Linkin park took me off guard lol
this video was good
Did you know? The Mohs hardness scale doesn't account for brittleness.
Attempting a 45° edge doesn't help either Edit: i retract this smart-ass comment. As a 45 woukd lro ably be the only way to get an edge. Any thinner and it does absolutly nothing but chip.
How long does your water jet stay sharp? I've been thinking of getting one but constantly having to buy blades for it is a lot of cost I am having a hard time justifying.
You have to stabilize this material to use it for any thing.
A harder blade looses strength. A diamond is super hard but when hit with a hammer it shatters.
no.
Yes hammers will break diamond just like every other rock type that doesn't have A LOT of metaloids. Not rly relevant to sharpening as it is abrasion not impact. The flaw was the sharpener. EDIT: I retract my statement and admit I had no idea hkw wrong I was. The brittleness of the stone makes it almost impossible to sharpen. Micro chips make big chips running water helps but only so much no matter what I tried the edge you would want is NOT obtainable with grinding. Wet paper stones diamonds no effect against the brittleness. the smallest movement pressure angle direction or the smallest particle of debri and your edge is gone. The sharpest I ever managed to make a piece of agatized wood was when it would chip. I apologize for my ignorance.
yooo mad props for the kiwami japan tribute
You should resin cast it THEN sharpen it, still petrified wood, just with some *assistance*
Nice knife
who would have known that that a tree growing in the forest 65 million years ago, would make it into a youtube video
You should do knifes with harder metals than steel and test them against a normal knife in sharpness, hardness and sharpness retention (tests like those in forged in fire)
Edge retention and durability generally come down to the heat treat, and since most steels have varying heat treats for their optimum hardness/durability, it'd be kindof a task to do all that. Especially since they don't necessarily research before jumping into it, I doubt it'd be anything really conclusive.
@@Bl4ckD0g I know they aren't scientists, my expectations aren't of a methodic and equally done testing, just for fun and general knowledge
Daaang.. imagine an obsidian blade with a petrified wood handle.
Reason why obsidian blades, and such is so sharp is because you should break off it in flakes, and use knapping. Trying to sharpen stone at best would result in edge what ever grit you have you use sharpening it with. Obsidian basicly is glass, and the flakes are incredibly sharp as you break them off
Excellent knife Mr. Waterjet Channel. You're doing the Lord's work!
Will they not let you use the newer water jet
What kind of warehouse is this and where can I apply for a job
50 million years is a clam that can't be proven with science I laugh
Good effort
Lol I though this was a kiwami japan video when I saw th title and thumb
Broham did not give that Wasp a fist bump when wherever and 30 feet away they spot me and they got the whole crew coming
As a fossil collector this video made me violently uncomfortable
I can't understand why the whetstone didn't work. You had the blade at the perfect 85° angle...
Gold. Underrated comment. A guided diamond wet stone would have had it splitting hairs. EDIT: I retract that. After probably a solid hour of attempting to put an edge on a small piece of agatized wood I find it next to impossible to aquire a thin edge. The brittleness of the stone makes it almost impossible to sharpen. Particles make Micro chips make big chips. running water helps but only so much. Wet sand paper,whet stones even guided,diamond stones no effect against the brittleness. the smallest movement pressure angle direction or the smallest particle of debri and your edge is gone. The sharpest I ever managed to make the piece was when it would chip
you now know my pain
I need you to make a sapphire or diamond knife next
yo this wood is sharper than my kitchenknife
all woods need to be "stabilized" this is done by putting it into a vacuum chamber with hard epoxy or natural mineral resin. the resin will seep into all cracks and once hard will hold the wood "stable".
Nothing is sharper than obsidian. A sharp knife at best is 3 atoms wide where Obsidian can be as low as 1.
There go three minutes of my life I won't get back!
i see that dank pods in that search bar. he be making some good ass content
A man of culture 🍻
Omg you guys need to mass produce this amazing invention
Kiwamijapan lend your strength to these people
What about cutting the knife from inside the center of the petrified wood? Instead of shaving a piece off? You would need relief cuts that you would remove afterwards probably by hand..
Are they for sale?
I'm dying at 3:55 LMAO
What happened to the original two guys? Don’t get me wrong, you guys are hilarious and I love your content!! Just curious if they are still involved.
I've been told they went to their own channel or something but have not been able to find it.
I was wondering the same thing
Wondering the same here.
It was allegedly announced at some point. I must have missed it.
If I find it I will post it.
You guys are a bit like the replacement Dukes of Hazzard.
Pet wood isn't 7 to 8 on the mohs, also it's not close to sapphire, like at all.
Just wait for Kiwami Japan to come back
Make me a “official waterjet beard comb” please. Yea thanks
I’ll never understand why TH-camrs just give up their channels
Now we try making knife from marble.
What's his name reminds me of Animal Mother from Full Metal Jacket.
Casually dabs up wasp
Tf bro dapped up a wasp 💀
When all else fails cast it in resin!
StOp WaIsTiNg FoOd
Where is the official taste tester at?
You guys have done the world's heaviest baseball and baseball bat. How about you try the heaviest golf ball and driver.
Wow cool
Make a metal handle, Opposite Day
The problem is that petrified wood is still wood.
Got there eventually
A cnc machine would do it justice
first time watching in a year, what happened to the other guys? i miss paul giamatti clone and the lick test
Remember when Dan and Mitchell where on this channel?>
Kiwami made a knife out of toe nails, beat that!
The sharpest object ever is a Tungsten needle. The tip of it is the width of a single Tungsten atom.
the first time i hear the word poutine in a youtube video
What about a power wheels update??
That be a wasp, not a bee
Blades are sharp but need To be more thin to cut well
Can anyone tell me the name of Dan and Mitchell's new channel?
should of gone with a larger cleaver concept knife, stronger, more to sharpen with probably 3.5ish inches high, full tang 3.5 inches x 1inch, 6 inch blade length, easier to sharpen and hold the integrity of the blade, more weight, less force required to chop, more height so you aren't malforming your cut angle reaching the wider section at the top of the blade early, basically just a smaller cleaver larger than your smaller cleaver
What about a Jade Blade
it needs to taper more. its to wide to narrow thats why its not working well. basically you got a wedge profile on the knife.
Just stopped by to say that it is a knife, not a saw! Just pull the blade through the tomato bro
obsidian is currently the sharpest blade humans produce, BTW obsidian is 5.5 Mohs petrified wood usually rates at 7. Flint is supreme in this range with Norfolk Flint being the best rating 8 Mohs.
I've sparked on all of these stones, which is a good test for them.
I have a huge petrified megladon shark tooth, possible blade from it?
If you want to send it we'll use it 😳
2"? A perfectly average knife length.
That's pretty big actually!
Not 50 million years old. Not even 10 thousand years old!
