M3 trench knife

The M3 trench knife, also called the M3 fighting knife, was an American military combat knife first issued in March 1943, during the Second World War. The infobox records a design date of 1943, production from March 1943 to August 1944 by firms including the Aerial Cutlery Company, and a total of 2,590,247 knives made. The page lists World War II as its war of use and does not name a specific armed force as operator. The entry therefore records a knife of American origin, issued in the middle of the war and built in very large numbers within about eighteen months of production, and leaves operator and service-status details for later sourcing.
