That's what I think... say it's D2, telling the difference between 60 Rc and 62 Rc in the field would be pretty hard I think. Probably could between the 57-58 Rc some production companies run D2 and the 60+ most custom makers treat to. Gotta get to that certain level and after that it's more a matter of grind, ect. that determines the performance of a blade rather than one or two points on the heat treat scale.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
