The cutlass remained an official weapon in United States Navy stores until 1949, though seldom used in training after the early 1930s. The last new model of cutlass adopted by the U.S. Navy was the Model 1917; although cutlasses made during World War II were called the Model 1941, they were only a slightly modified variant of the Model 1917. A United States Marine Corps engineer NCO is reported to have killed an enemy with a Model 1941 cutlass at Inchon during the Korean War. A cutlass is still carried by the recruit designated as the Recruit Chief Petty Officer for each training company unit of recruits while at the US Navy Recruit Training Command. In a message released 31 March 2010, the US Navy approved optional wear of a ceremonial cutlass as part of the Chief Petty Officer dress uniform, pending final design approval. That approval came in January 2011, and the cutlass was made available for ceremonial wear by Chief Petty Officers in August of that year.
