In the Broken Bow incident of 2151, the Klingon courier Klaang used his disruptor in Broken Bow, Oklahoma, on Earth. In that case, Klaang's disruptor was utilized to destroy a corn silo housing two Suliban agents. (ENT: "Broken Bow")
In 2259 of the alternate reality, Klingon disruptors were used in a battle between a Klingon patrol, an away party from the USS Enterprise and Khan Noonien Singh, a conflict which took place in the Ketha Province on Qo'noS. This style of Klingon disruptor could not only be used to fire at a target, but was also equipped with a double-blade on the front of the barrel and a spiked bottom edge of the handle.
