I recently acquired this knife that is clearly stamped FRAZIER. What's odd about it is that on the one side, I can faintly see where the name FRAZIER was stamped inverted, and then stamped over the other way. If you look closely at the pic of the stamping you can see part of the Z and the R. Can anyone explain that? Also, do you believe this is a Ron Frazier knife? There is a letter S stamped on the butt. I have no idea what that signifies.
