"The U.S. Marine Raider Stiletto was the first knife in United States Marine Corps history to be designed by a U.S. Marine Corps officer, the then Lieutenant Colonel Clifford H. Shuey, who retired as a Brigadier General and was formerly in charge of the Engineer Division at Headquarters Marine Corps. The knife was designed in 1942 and officially issued to the Marines.[1]"
