I doubt this knife was owned by or even made in the VietNam War era, but I'm sure Cruchtip can comment also. Telltale signs of a late 1970's (or newer) vintage are shining through. Also: I believe the finish on the blade is after-market. Welcome to our forums and please stick around.
Stay sharp, Capt. Chris
