Vos ignites the monomolecular laser sheaths that augment his petars. A specific type of energized sheath was the monomolecular energy cord, alternatively referred to as a monomolecular laser sheath. Monomolecular energy cords, functioning as energy filaments, found application in Kyuzo petars to enhance both the cutting effectiveness and the lethality of these weapons. These cords, supplied with power from rechargeable energy cells, were directed along the blade's conductive carbon edge. Dryden Vos ordered a specially made pair of petars incorporating monomolecular laser sheaths, employing them with lethal accuracy.
