I try to gloss over it as well, Thom.
Confederate, I can see the generalizations you're trying to make. Problem is, they do not work. at all. Benchmade & Spyderco use S30V. Is it premium or tough? I don't know. I do know BM uses it in the Rukus, Skirmish, Dejavoo, Ritter Griptilian, Opportunist. Spyderco uses it in the Chinook, Manix, Military, Native, P'Kal, T Mag, UK penknife, Caly 3. Which ones are made for batoning, which ones are diminutive and pointy? Which ones are full flat ground, which ones are saber ground, which ones are tough, which ones are not. What about the S30V Leek. Or the ZDP189 Leek. Or the ZDP189 Cyclone. Or the ZDP189 Endura. Is it as dainty as the Caly Jr, Jess Horn, Stretch II?
I don't want to get into how robust the linerlocks are on CRKTs and Kershaws. I'll just say that I completely, totally, and utterly disagree with that opinion.
Anyway, to the original point of the thread, I don't think the imaginary lines surrounding one piece of land from another have a hell of a lot to do with the ability of people living there to produce good cutlery.
