M-4 Utility Experimental Knife
Basic Information

The M-4 Experimental Utility Knife was manufactured at the Springfield Armory early in 1957 at the request of the U.S. Army Infantry Board, from M-4 bayonets. The blade has hard plastic grips that were easy to repair and were designed to resist fungus, unlike previous leather grip utility knives. Only 11 of these knives were made.
