Mike Grayman told me they come with a "toothy edge" for hard core use, it makes the the edge less susceptible to rolling and chipping when using the knife extremely hard. The edge is almost like a chisel grind edge. it really is only sharpened on the one side. I'll use this knife for awhile before I decide if I want a more refined edge put on it.
Miles a really nice guy. Mine was maybe a little extra rough, because it came with what almost looked like a serrated edge. Love the knife though. Probably the beefiest folder I've ever handled.
Very nice grunt soldier. I really like the orange handles, how about some specs on it?
