I'm lucky enough to have handled one of Pierre's razors, and let me tell you, they're pretty damn incredible.
Pierre -- is that up for sale, or are you just showing off?
I am putting my self on the line, and learning as much as I can as fast as I can as far as razors are concerned.
HT's for any given steel is the same whether knife or razor. Goal hardness may differ. Grinding is a complete rethink. Its similar to going from a hunting knife to a kitchen knife, as going from a kitchen knife to a razor. Grinding is a whole other issue. The thinness of the edge, doesn't leave a lot of wiggle room to prevent a grind through, on top of that you are grinding in a hollow, you cant see as easily, and its so thin, you have to be careful of heat so as not to wreck the temper. You have a couple hundred degrees , but in thin as foil steel, it can get there in seconds. as well all your belt covers 2/3's of the blade! so concentration becomes important.
Hey, I had to ask -- if it was for sale I was interested. But I figured you were just showing off...
Pierre, that one looks great. Very classy looking indeed!

Stoppit. Just stoppit Pierre. That looks too good. You're going to cause a rift in space due to the disproportionate amount of awesome in one place...
