 The M1859 NCO sword continues service today as the Marine Corps drill and ceremonial sword.The sword's use is restricted by regulation to ceremonial occasions by an NCO or Staff NCO in charge of troops under arms or at weddings and wedding receptions where at least one of those being married is in uniform and has the rank of Corporal or higher.The sword is patterned after the United States Army's foot officers' sword of 1850, with minor differences.
