Vibrostaves were melee weapons that came in single and double-bladed varieties. These staffs had a rounded hilt roughly three feet long, that contained a vibromotor, a mechanism that caused the blades to vibrate at an incredible speed, causing even the slightest glancing blow to become a gaping wound. The hilt also contained one or two blades roughly 2 ½ feet long, sharpened to a razor's edge that could be activated individually or simultaneously. The blades' cortosis weave allowed them to parry the blows of lightsabers, energy swords, or blaster bolts.
