[Source] A vibro-ax, or vibro-axe, was a type of ax that used a compact generator to create vibrations along the cutting edge's surface, which significantly increased the weapon's lethality. There existed one-handed and two-handed models. Similar vibration-based technology could be found in vibro-blades, vibro-knives, vibro-pikes, and vibro-lances. Vibro-axes were wielded by many thugs across the galaxy. The pig-like Gamorreans, for example, often used them. During the Galactic Civil War, some of those boar mercenaries favored a particular model of vibro-ax known as Arg'garok
