The electro sword represents a kind of short sword that was electrified, wielded by the Kage Warriors hailing from the planet called Quarzite. These electro swords functioned as melee weapons, yet they were frequently employed as blades for throwing, evidenced by Krismo Sodi's use of one to eliminate the Belugan Major named Rigosso.
Even though it was an energy-based weapon, the electro-sword was not comparable to a lightsaber, as the latter could bisect it with ease.
