I do my own heat treatment and protocols.

That is going to be incredible. Bye, bye grinding belts!!

I just got 71hrc....in my trousers! That is insane dude.

The 10v chefs knife was mind blowing enough, but the idea of this much Rex 121! You are redefining high end kitchen cutlery, and it's awesome to see it happening.

I can't wait to get one! Awesome stuff, love to see a maker of badassery hard at work. This is how we voluntarily want to lob Benjamins your way! Snapper season starts today on the gulf of Mexico, tomorrow I'm offshore bound 2 days one night, we'll fish around the clock till we run out of ice, wish I had a laser to work with on return!

Making custom glass cutters, and that chef is sweet too!

Damn, that's hard af, I don't want to know what that's like to grind or sand. I was just working with some M2 today at 65-66 HRC and my tungsten carbide drill bits were bucking and failing to drill through it. it took me ages to do anything with it. You're a crazy man. ++++

I tried that with my hair last week. It didn't turn out well!

[marvinberwart]

Amazed no one even mentioned the fancy bottle of Belgian beer you cut in this vid.

So what how do you think 15v compares to rex 121?? I've only worked with rex45 and 4V so far, that is as far as hard and toughened high speed tool steel's. I also heard that cpm even had 18v and even 20v at one point but decided not to invest too much into it primarily due to the weaknesses that occurred after adding to much vanadium.

No wonder this one is the strong silent type.😂

[skycorrigan]

This is fucking insane. I need to try this stuff!

[mehulmehta]

Crazy Knife!!
also can you review a Dulo knife?

[berzoidberg]

71hrc... that goes directly toe-to-toe with tungsten carbide blades. That's insane. How do I buy one?

[knifesharpeningnorway]

Pretty wicked mate. Wouldnt want to sharpen it though hehe

[j.shorter]

How does one achieve such great success as far as manipulating the properties of these crazy steels???

[sswwooppee]

So damn awesome... Do you find the diameter of the cryo chamber (I don’t know what it’s supposed to be called) limiting?

[FrumpyPumpkin]

So if this is the highest hardness, what’s left for extreme alloys in the future? Better overall properties?

[philipp]

How did the knife hold up? Did it crack with daily use?

[chocolatewhale]

I'm guessing cpm rex 121 is an extremely good steel sorry if my ignorance meter has skyrocketed I'm only 12 and don't know anything about steel in knives

[kevinfitz]

So epic holy shit! And how do you like delirium tremmens
