Daniel’s regular steel is one called 80Crv2. I have a Winkler Camp Knife forged from it, and it is tough stuff. According to Daniel, he went to CPM3V for the special edition because it has even more strength, and is pretty much the top performer for a knife like this. It is, however, tougher to sharpen (I’ve sharpened both steels, and find hardly any difference myself) and more expensive. The blade is Caswell finished (a hard coating that’s flat grey, or off grey) which prevents glare, and renders the knife rustproof.
