Bat'leth
From Tardis Wiki, the free Doctor Who reference
The bat'leth was a type of bladed weapon wielded by the Klingons in the parallel universe of the United Federation of Planets. They were retained even after the Klingon race had been converted by the Cybermen in an alternate timeline, with Cybermen being seen to wield them in the First City of Qo'noS. (COMIC: Assimilation²)
