Original WW2 era M3 Fighting Knife/Trench Knife – an early 6-groves handle M3 manufactured by manufactured by Imperial Knife Co. in Provenance, RI – one of the larger war-time makers of edged weapons for the US government. Out of the total of 2.5 million M3s made, Imperial produced about 850,000 M3s of all types by the time production ended in August 1944. Attached is the photo of the US Airborne paratroopers gearing up somewhere in England the day prior to D-day jump. One paratrooper has his trench knife on the hip; two other guys are armed with M3 fighting knifes tied to their legs (original photo is the courtesy of Wikipedia and is not included with the knife).

This fighting knife is used, but it’s in better-than-average condition for the type. This M3 is about 11-3/8” / 29 cm overall; the blade is about 6-1/2″ / 16.5 cm. The blade has been lightly re-sharpened; it is very sharp still; the tip is intact; no pitting or edge nicks. Stacked grooved leather washers and plastic spacers handle; steel guard and hammer-like pommel; all parts are tight with no play. The guard was originally marked but all original markings have been removed. Still, this is clearly one of M3s made by Imperial, judging from the distinct dark-brown plastic spacers at the ends of stacked leather washers handle. No edge nicks, contact marks or dings on the spine or the pommel; a few light rust spots near ricasso are noted for accuracy – cleanable.

Original M8 composition scabbard was manufactured by Beckwith Manufacturing Company; it’s marked US M8 / B.M. CO. on the throat. The scabbard is in very good overall condition, considering the age; the keeper is nice and tight; no rust on the webbing; and edge nick on the plastic near the tip is noted for accuracy. Overall, WW2 Imperial M3 trench knife is in 100% serviceable condition still; don’t miss your chance to add it to your collection!

This original WW2 Imperial M3 trench knife / M8 composition scabbard have not been cleaned or tampered with in any way, 100% original condition; these are the actual photos. Spent brass is not included with the knife 😉
