Maser Vibration Sword

A Maser Vibration Sword (メーザーバイブレーションソード, Mēzābaiburēshonsōdo) is a type of weapon that uses a combination of extremely high oscillation rates and temperatures in order to increase the cutting effectiveness of the weapon, thus this leads to the gray material suddenly becoming red. Due to some Maser Vibration Swords having similar oscillation rates, they can collide with each other without being cut. It can be inferred that the deeper the color of red it is, that the MVS blade becomes the sharper, stronger, and more durable. Rakshata created a variant of the Maser Vibration Sword known as the Revolving Blade Sword.

Background
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. The Galahad carries a Maser Vibration Sword known as "Excalibur," which was given to Bismarck Waldstein by emperor Charles zi Britannia himself which is extremely more powerful compared to a standard version as it is able to break through armor in a single swing, and is capable of generating an energy field that can block and slice through powerful energy blasts. The Tristan is equipped with two Maser Vibration Swords that combine to form a Polearm. Also, the Guren S.E.I.T.E.N. Eight Elements has a smaller, knife version of a MVS. Guilford's Gloucester was fitted with a pair of MVS stored in black scabbards on the sides of the Gloucester's cockpit.
