The Lancelot was the first Knightmare seen using a Maser Vibration Sword. The Lancelot's MVS is stored in sheaths attached, by the cross-guard being folded, to the cockpit block. Guilford's Gloucester was fitted with a pair of MVS identical to the Lancelot's, stored in black scabbards on the sides of the Gloucester's cockpit. The Lancelot Club equipped a variant of the Lancelot's MVS that could be combined into a dual-bladed lance-type weapon. The same weapon was later equipped to the Vincent and its successors. The Tristan is equipped with two MVS Polearms, long-shafted and short-bladed weapons that combine to form a long, dual-headed spear. Also, the Guren S.E.I.T.E.N. Eight Elements has a smaller MVS version of the original Guren's Fork Knife.
