Any bladed weapon enhanced by a rapidly oscillating augmented vibro-motor to amplify its cutting power was considered a vibro-weapon. The motor transformed even the smallest movement from the user into a stroke that could be incredibly powerful, even deadly.
Vibro weapons came in various forms, such as vibro-arbir blades, vibro-axes, vibrobayonets, vibroblades, vibrodaggers, vibro-knives, vibro-lances, vibroswords, vibro-voulges, vibrocleavers, and also vibro-machetes.
The SP-B50 blaster rifle represented a combination of a blaster weapon with a vibro-active force blade.
