Ref 745. USA. M1. Knife bayonet for use on the calibre .30–06 U.S. Rifle M1, designed by John Garand. Also used on the calibre .30–06 M1903 and M1903A3 rifles.
In 1942, the Cavalry Board recommended experimenting with a shorter blade of 10 inches. M1905 bayonets were cut down to 10 inches and designated M1905E1. 16-inch M3 scabbards were also shortened to M7 length. The shorter blade was found to be highly satisfactory and was adopted as standard in early 1943, designated Bayonet M1. The M1 bayonet was manufactured new with a 10-inch blade and black plastic grips. The M7 scabbard was manufactured new for the 10-inch bayonet.
