Have any of you guys worked with Hitachi 1 & 2, or the blue steels?

I am trying to find some HT info, and coming up lacking.

Anyone?
 
Murray Carter of Carter Cutlery uses them almost exclusively.. I'm not sure if he'd be willing to divulge those facts, as he charges a very pretty penny for classes but it might be worth asking him. He lived in Japan for many years and trained under a Japanese master smith apparently, so if its all true he'd be a great guy to ask for that sort of stuff. How much of it is marketing ? I don't know, but he seems to know his stuff that's for sure.
 
I'd be interested in finding some blue or white steel, I have looked to no avail. I think W2 might be close in composition but the Hitachi steels have more carbon.
 
Hengelo, that's a cool document. Thanks.

An interesting sentence pasted from it:

"Grinding.
It is very important to avoid temperatures above 150°C once it has been hardened and annealed. Grinding the steel on a dry sharpening machine or belt sander
is especially harmful its crystalline structure."

Click to expand...

150C = 302F so I can see why he would say that, it would start re tempering the blade. and we all know how fast that heat builds up on the blade while dry grinding.

I saw that site too, and thought "COOL! I can buy some paper steel!" until I figured out that for a piece of blue slightly more than a pound by weight, it would cost me like $90 total to get it here. Sheesh.
 
Yeah, it's much cheaper and easier to buy decent or even good blades made out of this stuff than it is to get the steel stock...
