A vibroknife, or vibro-knife, was a blade that used an internal generator to make the blade vibrate. These vibrations could make even a glancing blow into a huge, gruesome slash, thus making it a far more effective weapon in close combat, or as a tool. These small weapons were openly used by all denizens of the Galactic Republic, from clone commandos to regular citizens. A vibroknife was the primary weapon of choice of the Imperial Agent Cipher Nine.
