The Bat'leth is the Klingon longsword, designed by martial arts enthusiast and Star Trek: The Next Generation effects producer Dan Curry. The Bat'leth is a curved blade with spiked protrusions and three handholds along the middle of the blade's back. In battle, the handholds are used to twirl and spin the blade rapidly.
