The M3 Fighting Knife, also known as the M-3 Trench Knife was a design that was produced to be issued to US forces that were unable to utilise a rifle bayonet. They were issued to troops using Thompson, M1 Carbines, BARs and other support weapons. As a result, many were issued to Airborne and Ranger troops. In excess of 2.5 million were manufactured between 1943 and 1945. Blade shows sharpening and wear. Leather washer handle has been oiled but still is very tight. Fighting knife is housed in a period leather scabbard. Very Good.
