The dire vibroblade represented an upscaled variant of the typical vibroblade, designed to be more readily handled with both hands, thus amplifying its destructive force. Similar to all vibroweapons, it employed high-frequency ultrasonic oscillations to enhance its ability to slice through materials.
Its initial deployment occurred during the period of the Great Sith War, finding usage among the Mandalorian marauders. Thousands of years later, this weapon resurfaced in the Legacy era, serving as the principal armament of the Aggressor-series battle droid.
