I just bought these three knives from a flea market and wondered if anyone can tell me anything about them? The only make I can Identify is the Ka Bar one but I have no idea what kind of knife it is. The bone swiss army style one says made in U.S.A. on the blade but that's all. And the small wood one has a tang marking that is a crown over a scimitar and a word with the first letter(s?) rubbed off leaving "oxin". Any info anyone can give would be greatly appreciated.
