I have read that during the Vietnam war that the PX,s in the RVN refused to carry that model when it was called a Fighting knife,so Gerber renamed it a survival knife.I also heard two different reasons for the angled blade,the first was it was angled that way for a kidney stab,the second which sounds more realistic was that it was that way to stay closer to the body when worn on the LBE.Any one know the real story behind these tales?
