I just did some reading about k390
Needless to say, I must make something with it. I ordered enough for a large tanto and a santoku. I'm wondering if it will take an edge worthy of a straight...

There is everything to be said for that approach. it's traditional, well understood, and produces consistent results. For me, though, it just lacks that shiny-new-toy allure, the cutting-edge...

Cryo cycles refine the grain, which is important for razors. As to which materials merit them and which don't, I'm not sure. I've only recently begun learning about metallurgy.

Does anyone know...

I'm intrigued
Nitrobe 77 has .1%C and .9%N, but hardens to RCs generally only attainable by high carbon steels.
Am I to understand, then, that N plays a similar role as Carbon?
The only concern...

True, My point was just that toughness is less important than edge retention
I am almost done grinding the cpm 154. I'm going to grind a couple in 1095 and one in m390, then send them all out...

Heavy test conditions dont concern me, no one in their right mind expects a .025μ edge to survive wood chopping. Razors are ht'd to high rc hardness, making them relatively brittle. Toughness is...

Zdp 189 I think would be a good choice, but aks is out. Theyre where I have bought steel in the past. My concern with s90v is that i understand s_0v series steels to have toothy edges, better for...

I'm looking for overkill specifically for the coolness factor. If Ijust wanted to shave, I would have stuck with my mach 3.
I dont have any way to ht myself. I will send everything to Peters HT

I'm wondering about A-2
The common theme in good razor steel seems to be low vanadium (largest carbides) and high carbon. A2 fits the bill! And I read that it specifically is designed to be an...

This is the question. At the keenness required of a razor, would cobalt be too soft? I dont want to be the one to shell out the kind of money it would take to perform this experiment unless I knew.

I know that cpm 154 is a lot like ats34, which I believe mastro livi has used. The difference is in the cpm, which can only improve the grain characteristics. It seems the obvious choice for a ss...

I have cpm 154 that I just ground my first razor from. I have 1095 as well, and m390

I am wondering if m390 has a fine enough grain structure for a razor

Is there a "best" straight razor...
