The main-line American Army fighting knife of World War II, the M3 knife was introduced to service with the right flat of the blade used as a location for the maker's marks. While a nice, broad canvas, concerns were raised that the blade stamps could have a negative effect on the strength of the knife, so only the earliest M3s are so marked. 11 1/2 inches overall, with a blued 6 5/8 inch blade with a spear point, sharpened false edge, and "U.S. M3 KINFOLKS 1943" on the right flat. The guard and pommel are blued, with the guard unmarked and a "flaming bomb" stamp on the pommel next to the tang, and a ribbed leather washer grip. With a brown leather Milsco M6 sheath, dated 1943 with steel reinforcement plates and integral hanger.

Very good, with 80% plus bright original blue finish. The blade shows some specks of rust and pitting on the guard and pommel, concentrated where the leather and steel meet. A few of the washers near the pommel are stained and split, otherwise the grip is very fine. The sheath is exceptionally fine, with mild stains and scuffs. One will look for a long time to find a better M3!
