A new knife I finished yesterday for a local customer.

3.75" blade in diferentially hardened and etched D2.
Handle in Itin wood (a wood from Northern Argentina), with guard in nickel silver and copper.

Nice looking knife ofr sure, but one question. How do you differentially harden D-2, as it is an air hardening tool steel? Or is that a trade secret? The hardened zone is quite apparent, and so is the grain. I know Thomas Haslinger has accomplished this with S30V and other air hardening steels, but he's not talking! Just curious.

Clint,

You can also use oil for D2, that's what I use :)

And it's no trade secret, I use a torch to heat the part to harden and then quench it on oil at 70C.

Then I heat the entire piece at about 250C and quench it on oil at 70C again to release tensions.

This way I get a hardened sector at 61RC with a spine at RC55.

Very nice looking knives on your website!

Ariel-

Do you submerge the whole blade during the first quench or just the hot edge?

And how did you finish it to bring out the hamon so vividly?

It's a beautiful piece of work.

Allin,

I submerge the blade entirely, not just the hot edge.

As for the finish and hamon line, I clean the blade and place it on a container with iron perchloride, and the steel get that way due to the high carbon content of the D2.

Ariel
