Adopted in late 1918, most Mark I knives were completed too late to see service in the trenches of World War I. During World War II, the Mark I was issued in 1942 and 1943 to airborne troops, Army Rangers, and Marine Raiders. The U.S. Army adopted the M3 fighting knife as a replacement for the Mark I in 1943.
