Just out of curiosity, are those str8 looking blades on some styles of folding pocket knives ground to the same blade geometry as say a 3/8 or 4/8 razor? If they lay down on a stone at the correct angle, one could theoretically get one shave-ready. I'd assume the steels used would be of sufficient grade to take and hold such an edge. Maybe not, but if it were a Puma or such? Being a knife guy, I always wondered about that type of knife. Why did they ever make such blades for pocket knives if not to shave with at some point long ago? I can understand nowadays it being just a gimmick, but still I wonder.....
