The Treppus-2 vibroknife, a notable vibro-knife model, was manufactured by Merr-Sonn Munitions, Inc.. Serving as a typical vibroblade, the Treppus-2 became the foundation for Merr-Sonn's M8 Combat Knife, utilized by the Galactic Republic's clone troopers during the time of the Clone Wars.
The Treppus-2's blade measured approximately fifteen centimeters in length. Often, activation was achieved via a button situated on the weapon's handle, and it was programmable to activate immediately upon removal from its carrying case. In addition, the energy cell powering the Treppus-2 was housed within the handle, providing ten hours of continuous use per charge. As an option, a charging device could be incorporated into the knife's holster, ensuring constant readiness.
The initial mention of the Treppus-2 vibroknife in current Star Wars canon occurred within Rise of the Separatists, a 2019 addition to Fantasy Flight Games' Star Wars Roleplaying series. Within the Star Wars Legends continuity, the Treppus-2 vibroblade was first documented in The Essential Guide to Weapons and Technology, a 1997 reference work penned by Bill Smith. It subsequently appeared in a flashback sequence in Rebel Force: Renegade, a 2009 novel written by Alex Wheeler.
