The sword is the original bat'leth, used by Kahless to defeat the tyrant Molor.
After Toral is subdued, Kor and Worf again attack each other.
Jadzia shoots them both with her phaser set to stun and then forces Toral to deactivate the transport blocker so that the three can return to the Runabout.
"The Sword of Kahless" is the 81st episode of the American science fiction television series Star Trek: Deep Space Nine, the ninth of the fourth season.
It originally aired on November 20, 1995 in broadcast syndication.
This meant that in each of those episodes, Worf was inserted into the episode, whereas "The Sword of Kahless" was the first episode to be written after his arrival and the production team wanted him to feature centrally for the first time.
The story was created by Richard Danus, who had been the executive story editor during the third season of TNG, when Ira Steven Behr joined the production team.Kor begins to talk about how it would allow him to overthrow Chancellor Gowron and Emperor Kahless II but Worf says that he should be the one to lead their people.Suddenly, Kor slips down the side of a cliff but refuses to let go of the sword.Michael Dorn had joined the cast at the beginning of season four, but his character was not featured prominently in the first eight episodes of the season because they had been scripted prior to confirmation that Dorn would be joining the show."The Sword of Kahless" was the first episode to be written after his arrival, so it was the first time his character was featured centrally.Kor, Worf and Jadzia fight past Toral and his men and after finding that they cannot transport back to the Runabout in orbit, they head into the adjoining cave system in order to try to get out of range of whatever Toral is using to block the transporter.
