This item is a replica rubber KABAR style combat knife. The KABAR is also known more correctly as the USN MkII or the U.S.M.C. fighting/utility knife. It was cast from an actual USN MkII knife, ordinance marks and all other identifiers in place. This particular replica is blade marked "Robeson Shuredge" on one side and "U.S.N. Mark 2" on the other. The rubber is durable, flexible, and the edges are not sharp. It is a good alternative to carrying your expensive original into the field, or an excellent display piece. The knife was cast in a silicone mold so it holds all of the detail of the original.The knife is cast all black, but you can paint the handle brown for increased authenticity. Makes a great movie or play prop!
