World's Sharpest Rock Knife 

Join the Official Waterjet Channel Discord! We'd love to hear from you! discord.gg/t4KFPeMvBc

2:14 After thorough research and multiple hours of professional documentation, I can confirm that it is a rock

I thought this was a Kiwami Japan video and I was so incredibly exited. however, seeing that it was made by the water jet channel didn't change my exitedness

That pink rock could be quartzite, I'd need to see it in person. Also, I'm not so familiar with the geology of the US.

No one's mentioning the cameo of Nate. Damn.

WJC has finally reached the stone age. From super conductors to stones. Truly a devolution

I think the pink rock is regular granite with pink plagioclase in it and the white granite you have might be something like granodiorite.

I am a local geologist and rockhounding expert here in Utah, anyway I could help you source some rocks for your videos if you want. Show you where to find the most interesting material to make the knifes out of.

Bro you can't just Nate jumpscare us like that.

3:41 WAIT WHAT

You should make the heaviest American football ball

I was diagnosed with autism after subscribing to this channel.

@0:50 had me rolling.

Whaaat?!? People make make mean comments about you? You're the only reason I watch this channel. Also never stop wearing those overalls.

I asked a 2011 kitchen-makeover mom what that pink rock was and she said it was 'Pinkstonite'. She also said she liked hard pink things.

You and the salt fork guy should collab! Make a salt knife!

4:40 they are just slim Jim’s

It’s not just a boulder, it’s a rock!

Next up: world’s sharpest knife made out of orbeez cast in resin

Got me with the Nathan surprise and the spongebob reference

I appreciate all of Dans sound effects when he describes what hes doing

A knife you can truly take for granite

If you want a wider selection of rocks to work with, then I suggest going to the Tucson gem and mineral show. It's the largest gem show on the planet, and people bring rocks from all over the world to sell. No joke. It takes place the first 2 weeks of February every year. I went once. They had booths all over the city, and I saw rocks as big as cars for sale

Rock scissors 🪨📃✂️

2:09 "I'm not a rapper!"

08:25 "If there's anything I know is edging". Now I paid good money for those videos ;)

I make jewelry using crystals and minerals. Try and take a knife to the pink stone and see if it scratches. If it does my guess would be feldspar. If it doesn't scratch then maybe rose quartz.

Hey! I picked granite countertops because I liked the way it looked! And it's easy to clean and durable and waterproof when sealed!

You guys deserve tons more views and subs

" 5:32 " Bro forgot he had a waterjet 💀💀

the “this is the place” joke was severely underrated. 10/10

The unidentified rock is likely some sort of Rose Quartz Agate or just straight up Rose Quartz, this wouldn't be too unusually since rose quartz is somewhat common in new hampshire and the northeast!

I didn't know this series was a thing, this takes me way back, I remember seeing a bunch of asmr like videos of weird knifes from a japanese channel like 6 years ago. Time to binge all of these, they may not be as satisfiying, but I don't care. I needed this shit back in my life.

Mom joke earned an instant sub. 😂😂

i can confirm this knife is very sharp

That pink Rock looks straight up like a piece of pork. I was thinking this exact thing and then all of a sudden, then he said, "that looks like a nice pork chop". had me cracking up.

Its not just a boulder.. Its a ROCK! 🥺

This was a very interesting concept. The granite was very beautiful. I found a rock almost like the pink one in the graveyard in my yard. I'm trying to find out exactly what kind it is. If I find out, you'll be the first peep to know.

This video Rocks!

It looks like Quartzite or could be Rose Quartz

That scene with the TKOR statue and Nate himself really messed with my mind for a few seconds. Like what just happened. And its funny how the video just carries on like nothing interesting just took place...

This is the earliest I’ve found one of your videos, continue the mom jokes bte 0:30

That pink rock is 100% rock. Nice find!

this might be the first time... a channel was bought out and im still subbed and enjoying the content... this dude is super chill and hoestly has really good content... just what im looking for.. and not far off the waterjet channels fan base. I love it keep it up. sad to see the old boys go. but this channel will live... thank you.

Only Utah natives will fully understand why 1:14 is so funny 😂

Water jet channel just doing side quests 😂

Got jumpscared by the mention of Salt lake. I live in Utah but in a different part of Utah

That title and thumbnail, you had me super hyped that Kiwami posted a new vid, I'll still watch though

Now I know how the natives made knives. Very educational video.

demonios amigo, esta traducción al español es maravillosa, las emociones del presentador las puedo sentir en cada palabra que dice el traductor, magnificol.

The sharp knife is quartzite, which was originally sandstone but has been heated and squeezed to the point where it recrystallized. The layers are remnants of the original sandstone. Quartz is very hard and pretty strong so it makes a pretty good knife blade, good work!

Hear me out, make a knife from a Arkansas black hard stone a stone used for sharpening knives made into. . . . . You guessed it, A KNIFE!!!

Walked up to a knife salesman i said “here is 100,000$ can i buy a knife?” He said “No! Money can’t buy knives”

I think I drank too much water, that Nate cutout came to life 😮

I like your overalls

Uranium is very sharp use that! One of my friends used it He has not called me never since... Because he's so busy Cutting stuff I guess 😅....

Well, one thing's for sure. You shouldn't take that knife for granite-d

the mystery rock is quartz with some sort of red impurity the Aztecs used quartz for arrowheads, spearheads, sacrificial knives medicinal knives axe heads and lots more.

‘cracks? i hardly know her’ LMAO

For rock you would want churt, American black flint, crystal quartz, British blue flint, or obsidian.

When you use the table saw please cut with the grain, so basically cut with the direction of the lines

"Was that a Destiny 2 reference?" He's out here rockin the final shape with this water jet.

Good job! That sharpening stone seemed awesome! BTW you are frickin' hilarious!

The pink rock definietly look like it could be pink quartz.

Yesss, i love these knife videos ! Way to swallow that beef stick ! 😂😂😂

I took the other knifes for granted

The strange stone looks like a cryptocrystalline quartz type, but there's SO many stones of that type simply looking it through the screen would tell us nothing about it.

bro is giving us signs 😂😂

so, looking at the pink rock it looks like Keokuk, but it is hard to diagnose without handling it. but it is a kind of knapable stone that is on par with flint or obsidian

Make a knife with the hardest wood, red quebracho

Bro is using water on a diamond stone 😂😂

i believe the pink rock is rose quartz. 2:14

That 🪨 ROCKS!!!

The pink deposit is pink quartz. Granite is actually a type of quartz. It's merely marbled quartz.

2:45 I felt that 💀

Your like the nerd in school that the jocks should have spent time with because now you have a million sub youtube channel

"Back in rock town it's time to cut these into a knife shape and get them close to the final shape." (Was that a destiny 2 reference) Yes it is a reference and I play the game

Has a waterjet: uses a hammer...

might be worth trying to find some "Banded Gneiss" (yes, it's really pronounced like the word "nice", so you can make all the dumb puns you want with that) that has some nice straight lines in it. it's a different type of granite, but should work better than the mottled variety you used here. not sure what that pink rock was, though others seem to think it's pink quartz. if you wanna try doing something REALLY fancy, you can actually grow your very own rubies an arc welder with carbon rods, and a chunk of graphite. rubies are a material called Corundum (same as sapphires), that's a 9 on a mohs hardness scale, only 1 below diamond. it should be able to get sharpened into a VERY sharp edge, and also be fairly durable. I would strongly recommend checking out NightHawkinLight's older video on making rubies, but instead of making a small bowl that produces a button, make longer square mold for a bar, or even just buying a graphite mold meant for making gold bars. it's a pretty simple process.

This changes the game of rock papers scissors. Rock now beats paper, and scissors beats rock and paper.

I was not expecting the Nate cameo for 10 frames. 😂

It's crazy seeing the difference in quality of this guy's earlier to newer videos! I stopped watching for a while and came back to THIS!

Dawg what happened to this channel. There used to be three guys working in a workshop with a massive water jet and they cut things like glass or the once cut a switch device for video games or once they cut a box spring into the shape of a person after they compacted it down with the forklift. I remember they played music when they'd show the water jet cutting things. Time has changed Man I used to watch these guys when I'm 15 now I'm 21 years old about to be 22

close enough, welcome back Kiwami Japan

Not surprised the pink rock broke up like that, appears to be Quartz and is fairly brittle to blunt force

THE FINAL SHAPE‼

If we had wateriest, the Stone Age never would have ended.

Vitrified rock like obsidian, gets a glass like surface slowly heat until vitrification an allowed to cools slowly

"I don't have ADHD, I'm just optimizing my life for better retention" 😂 why does that hit so close to home

For sure this is very healthy! LOL

Pink rock looks like come quartzite. I found some and tumbed it and my mom thought it was raw chicken.

Thank you for carrying on Kiwami Japan's legacy.

How would a glass knife do? I would love to see a attapt at that with different harnesses and just for the lols just see if you can turn your glasses into a knife like the optics turned lethal

bro it's wood, stone, THEN metal, you can't just go back a technological age

6:16 i unironically thought the same thing before u said it
