Camillus Cutlery Co. began manufacturing the M3 Trench Knife in 1943. These knives were used by ground forces of the Army/Air Force,
tank units and specialized commando units.
Only the M3's made during 1943 had the year of manufacture stamped on the blade. A total of 402,909 M3's were made by Camillus during WWII.
I have the original WWII records for this knife. If you would like copies, without charge, just email me a postal mailing address.
