 In Star Trek lore, the Klingon Kahless created the bat 'leth around 625 A.D. According to Klingon mythology, he formed the blade by dropping a length of his hair into some lava from inside the Kri'stak Volcano, then cooling, shaping, and hardening it in the lake of Lursor. He then united Qo 'noS, the Klingon homeworld by killing a tyrant named Molor with the weapon, which became known as the "Sword of Kahless". The sword was later stolen by a species called the Hur'q during their invasion of Qo 'noS. In the Deep Space Nine episode "The Sword of Kahless", Worf and another Klingon named Kor rediscover the artifact, but it is eventually transported into space to prevent them from using it to attack each other. The Sword of Kahless differs from normal bat'leths as it has five points and one handhold compared to four points and three handholds.
