The following weapons were used by the Ennis and Nol-Ennis on the penal moon in 2369.
Blade weapons
The Ennis and Nol-Ennis used three different types of blade weapons, a lance like, a knife, and a tomahawk. The weapons were sharpened and used to stab their enemies or to cut their throats. Due to the artificial microbes no one was killed although their wounds were healing slowly. (DS9: "Battle Lines")
Energy weapons
The Ennis and Nol-Ennis used energy weapons beside their blade weapons in combat, although Golin Shel-la stated that they did not use energy weapons anymore because the damage to the body was not enough. (DS9: "Battle Lines")
Background
The blade weapons except the knife of the Ennis and Nol-Ennis were created by stuntman Tom Morga. He did so by taping together a cardboard blade, a ball and an old tool handle. (Star Trek Monthly #127)
