Add extra authenticity to your costume with this soft foam replica of the most honorable weapon of all, the Klingon Bat’leth!
Modeled on an actual prop used on screen in Star Trek: The Next Generation, the foam construction makes it perfectly safe — yet the detailed paint deco is so realistic you may mistake it for a lock of Kahless’ own hair dipped in lava and twisted into a weapon to make empires tremble. Measures a massive 4 feet long.
