For sale is a 1943 dated Case Cutlery M3 fighting knife with updated USM8 scabbard. This is the Case M3 with the blued metal. Other than a quick cleaning, we've done nothing to this set. The blade itself is in good condition with great markings and decent bluing remains. The handle looks like it may be missing the 9th groove and the knife butt looks to have been reworked. All in all a great addition to anyones collection.
The M3 Fighting knife or M3 trench knife was an American military combat knife first issued in March 1943. It was originally designated for issue to soldiers not otherwise equipped with a bayonet. However, it was particularly designed for use by elite forces in need of a close-combat knife such as Airborne troops and Army Rangers whose units received priority for the M3 at the start of production. As more M3 knives became available in 1943 and 1944, the knife was issued to other soldiers such as Army Air Corp crewmen and soldiers not otherwise equipped with a bayonet, including soldiers issued the M1 Carbine or a submachine gun.
The first version of this knife was blade-marked and dated. The second version was also blade-marked, but did not have the year included in the stamping. The 3rd version was blade-guard marked.

Case & Sons, Imperial Knife Company, Kinfolks Inc., Pal Blade & Tool Co., Roberson Cutlery Co., and Utica Cutlery Co. The M3 trench knife was discontinued in August 1944, after the M1 Carbine was modified to accept a knife-type bayonet.
