I recently inherited a KABAR . I am a Marine veteran and have a new unused real Kabar and this sure has the look and feel of a real Kabar. The sheath is very old and actually has a name and a service number carved into it. It also has the date April, 1951 carved into the sheath and the initials USMC are also carved into it . All carving into the leather is not by the sheath maker. I see no stamps or maker marks on the blade or handle of the knife. Any advice appreciated.
