The Boker USA Plus M3 Trench Fixed Blade Knife was designed in 1943 and was intended to be used by any U.S. soldier during World War II who was not equipped with a bayonet - soldiers with pistols, submachine guns, light and heavy machine guns, etc. The first troops to receive the Boker USA Plus M3 Trench Knives were the Airborne, Mountain Ranger and Glider infantry units. Among the nine manufacturers who produced the Boker USA Plus M3 Trench Knife during wartime was H. Boker & Co., with a total of 31,300 pieces, which was the smallest quantity. For the 65th anniversary, Boker is reintroducing this classic piece of tactical cutlery, along with a reproduction metal U.S. M8A1 scabbard. The black coated blade is made of high carbon SK-5 steel, features the original H. Boker & Co. blade tang, and the handle is made of stacked leather pieces. To ensure the quality of the Boker USA Plus M3 Trench Tactical Knife w/ Leather Handle, each knife features a laser engraved serial number.
