Nitrobe 77

Yesterday finished ht my 5 inch (32mm thickness) Nitrobe blade. Performs excellent at 62 hrc. Sharpens and polishes easily. Stuck it into dishwasher, wiped it, no consequences to the mirror finish. Jammed at approx. 3inches from the tip and did some pull-ups on it, no problem there (nearly 200 pounds of weight). As per cutting performance, hard to tell, since the geometry is different from other knives made by me. But it's definitely not worse than RWL34 at the same hrc. Bad thing- due to de-nitrification lost 1.-1.5mm of edge (had to grind back and resharpen). Still testing it. Next buy 40mm thickness. If interested in another testing method, let me know.
P.s. Brisa's Nitrobe is overpriced.

You guys have peaked my interest in this steel but I gotta say this knife looks like a great design regardless of steel choice. It looks like a great kitchen knife that, when popped into a sheath, makes a great hiking knife too. Cool design.
 
Right on, Thanks man :D
I'm a huge fan of traditional American frontiers men style knives.

Here is the update to Nitrobe77, it's 63rc
Finally ground out the blade. It's incredibly thin behind the edge.




This steel has insane stability. It can go thinner then most steels.

It sharpens easier then anything I've used so far. Its not "gummy" either, deburrs like a champ and gets very, very crisp.

I like this steel alot.

Raw material is very, very, very expensive though. Nitrobe77 Costs more then Maxamet, rex121, cpm125v and CPM 15V

However it might be the king of edge stability.

HUGE THANKS to Des Horn for helping me with the HT protocol.

He is truly the Nitrobe77 Master.

This a a very unique steel.
 
Came out very nice. Used a special piece of micarta that was pressed curvy with two alternating colors and cross cut. Very cool stuff, it's made by Greg Hanson In California at "Unique Micarta"

Looks Like ocean waves.

Perfect for a steel that almost replaces the carbon but has a great working Hardness of 63rc.

This is probably one of my favorite steels.
It begs for thin geometry. It's a laser steel.

Sharpens better then Hitachi Shirogami "White paper" 1a carbon steel. Yet, holds a longer edge and has superior stability, doesn't microchip.

Given the extreme cost, availability and extra steps with Heat treatment that are not mass production friendly it's safe to say you'll never see this steel in production knives.

What's the edge stability like at that geometry and hardness? Beautiful knife!!
 
Very nice DeadboxHero DeadboxHero
If it's not a secret can you tell me the routine to push the steel to 63hrc? I tried the same routine as with rwl34 on small pieces i got as samples, but only managed 61hrc :/ I would like to make a decent slicer out of it.
