Explosive knives, utilized by Riff Tamson throughout the Clone Wars, were a specific variant of knives.
In the climactic battle of the Battle of Mon Cala, Riff Tamson, representing the Confederacy of Independent Systems, deployed four explosive knives, resulting in the death of two Mon Cala soldiers, a single Quarren soldier, and a single Gungan soldier.
Subsequently, Tamson fought Prince Lee-Char, who managed to seize one explosive knife. Lee-Char activated the blade and then impaled Tamson by hurling the knife at him, functioning similarly to a spear. Incapable of dislodging the knife, Tamson opted to charge forward, which allowed Lee-Char to fire the detonator. This action resulted in Tamson's demise, thereby avenging the death of his father.
