Vibro double-blade
From Wookieepedia, the Star Wars wiki.
The Vibro double-blade was a variation of the more common vibroblade. This twin blade variation used Echani cortosis-weave technology which was heavier and less precise, but more powerful than its single-bladed cousin. Kir Kanos and some of the Emperor's Royal Guard used Vibro double-blades with retractable blades. Ludo Kressh possibly used one, as did Marl the duelist from Taris, and the Sith Governor of Taris. The double-blade, like the double-bladed lightsaber, was difficult to master but could provide an advantage in battle. In addition, double-blades generally tended to cost more than the standard vibroblade. The accuracy of this weapon was questioned in the fact that it was a supposed cousin of the Force pike and the double-bladed lightsaber. Like its Jedi-weapon cousin, a vibro double-blade could cut the wielder in half, the wielder in turn had to be specifically trained to handle the weapon. Someone inexperienced with the weapon would likely injure themselves to the point to maiming or killing themselves.
