I think they should be .275" stock.. If you want to actually cut stuff you don't buy Busse-kin (unless you live near to Horndog!), Mora's cut stuff, Busse-kin beat trees or concrete blocks to death!
(I'm happy to retract this if Dan assures me they have retrained or dragged out and shot the bloke at the factory who can't grind edges with an inclusive angle of less than about 70 degrees!) <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Seriously though, the 3/16" seems ideal for this kind of knife.. (Even better in INFI) <img src="/ubbthreads/images/graemlins/crossfingers.gif" alt="" />
