The bat'leth, or "sword of honor", was a traditional Klingon bladed weapon. While Klingons often carried disruptors, they preferred to use bladed weapons in combat, with the two most common ones being the bat'leth and the mek'leth. (ENT: "Marauders")

A person wounded by a bat'leth might be said to have been "bat'lethed". (VOY: "The Killing Game")


According to T'Pol, the bat'leth was described as "a curved, bilateral sword" that "can decapitate its victim with one stroke." (ENT: "Marauders")

A "warrior's configuration" for a bat'leth was "tip to tip 116 centimeters, weight five point three kilos with an exterior handgripping diameter of five centimeters [with] blades composite baakonite." (DS9: "Blood Oath")

In 2376, a comatose B'Elanna Torres dreamed about exploring her Klingon heritage with Tuvok. He presented her with a bat'leth and told her to describe the first thoughts that came to mind. According to Torres, "It's a clumsy weapon. Awkward and overstated like everything else Klingon." Tuvok, however, felt that she could not "see the elegance of its design" because of her hatred, further describing it himself, as "A warrior's blade. Crafted for balance and precision." (VOY: "Barge of the Dead")


Early bat'leths, such as the Sword of Kahless, did not have separated lateral grips and featured an additional prong at the center. One such bat'leth was owned by Kohlar's great-grandfather. Another was possessed by the Zibalian collector Kerner Hauze. (DS9: "The Sword of Kahless"; VOY: "Prophecy"; LD: "Kayshon, His Eyes Open")

At the time of the Federation-Klingon War of 2256-57, the common bat'leth design featured an inner pair of shorter, forward-facing blades and an outer pair of longer, backward-facing blades. (DIS: "Battle at the Binary Stars")

In the alternate reality, a Klingon patrol in 2259 wielded bat'leths with three pairs of outer blades. (Star Trek Into Darkness)


According to Klingon mythology, the first bat'leth was forged by Kahless the Unforgettable in the 9th century. Kahless cut a lock of his hair and dropped it into the lava of the Kri'stak volcano, then plunged the burning lock into the Lake of Lusor and twisted it into a blade. After forging the weapon, he used it to fight the tyrant Molor, and then gave it its name. This story was not recorded in public texts, but was passed down verbally by the Klingon clerics as a test of Kahless' return. (TNG: "Rightful Heir") (See also: The Story of the Promise)

The Sword of Kahless was preserved by the Klingons following Kahless' death, until it was stolen by the Hur'q when they plundered Qo'noS about five hundred years after his death. (DS9: "The Sword of Kahless")

Bat'leth were among the weapons collected by Captain Gabriel Lorca aboard USS Discovery in 2256, as part of his mission to find means to help win the Federation-Klingon War. (DIS: "Magic to Make the Sanest Man Go Mad")

Worf owned a bat'leth that had been in his family for ten generations. After his mate K'Ehleyr was murdered by Duras, Worf used this weapon to kill Duras in honorable combat. (TNG: "Reunion")

During his time aboard the USS Enterprise-D, Worf trained both William T. Riker and Beverly Crusher in the use of the bat'leth. (TNG: "The Quality of Life", "The Pegasus")

Tom Paris once trained in the use of a bat'leth in a martial arts program with B'Elanna Torres. He considered it the best workout he had ever had and, more than that, an art form that required one to use both their mind and body. Torres, however, struggled against her Klingon heritage and did not have much enthusiasm for the program. (VOY: "Displaced")

During the final duel between Worf and Chancellor Gowron using bat'leths, one side of Worf's weapon was shattered when it was struck while in a bad position. Worf resourcefully used the separated blades as combat knives and continued on to kill Gowron. (DS9: "Tacking Into the Wind")

In 2380, Lieutenant Shaxs tried to gift a bat'leth to Ensign Beckett Mariner after learning that she was the daughter of Captain Carol Freeman. (LD: "No Small Parts")

In 2401, Worf used his bat'leth to kill Sneed after the Ferengi double-crossed Raffi Musiker and drugged her. (PIC: "Disengage")

Alternate timelines and realities[]

A bat'leth was displayed, among other trophies, in a mountain cabin where James T. Kirk resided in the early 2280s, as re-created by the Nexus. (Star Trek Generations)

In the alternate reality, at least two Klingon warriors wielded bat'leths in a battle between a Klingon patrol, a USS Enterprise away team led by James T. Kirk, and "John Harrison", in the Ketha Province. (Star Trek Into Darkness)

The props department which worked on Star Trek Into Darkness was very interested in revising the bat'leth, if Director J.J. Abrams chose to include such a style of weapon in the movie. Prop master Andrew Siegel remembered, "We really wanted to have that as an option for J.J. to use. In keeping with the style of all the other stuff, and the costumes, it was about updating the Bat'leth. Design-wise, it was pretty simple, because it's a shape that has been established, and we just refined it. Then it was just a matter of size, and making something that big that wouldn't kill someone in real life!" (Star Trek Magazine issue 173, p. 78)

Background information[]

Training for a stunt involving bat'leths, during production on TNG: "Firstborn"

Although this weapon has become known as a bat'leth, it was initially to be named a bat'telh, which the pronunciation guide from the final-draft script for TNG: "Reunion" recommended be pronounced "BAT-telth". The scripts which referred to it with this name included not only that for "Reunion" but also those of "Night Terrors", "Redemption", "New Ground", and "The Quality of Life". [1] [2] [3] [4] [5] However, in the script for "Apocalypse Rising", the name "bat'leth" was notated to be pronounced as "BAT-'leth". [6]

In non-canon Klingonese devised by Marc Okrand, the Klingon word for this weapon is "betleH", etymologically derived from "batlh 'etlh" (literally translated as "glory blade"). Stated "Reunion" co-writer Ronald D. Moore, "I think I pulled 'bat'leth' from the dictionary by combining, like, the word for 'sword' and the word for 'honor,' and I think I literally combined them into 'bat'leth.' So, I think that was kinda rooted in Marc's language." ("Reunion" audio commentary, TNG Season 4 Blu-ray)


Introduced in "Reunion", the bat'leth was originally inspired by comments from Worf actor Michael Dorn, as he wanted his character's fighting style to be more martial arts than barbarian, which synced well with writer Ronald D. Moore thinking of the Klingons as akin to samurai. (Star Trek: Communicator issue 114, p. 59) "You know, there was this desire to have a particular, cool Klingon sword for Worf to use, that would become his, sort of, signature weapon," remembered Moore, "and Michael Dorn had actually always asked for this. He would always, like, say that he wanted a cool weapon that was just Worf's." ("Reunion" audio commentary, TNG Season 4 Blu-ray) Dorn's remarks led Moore to think up the bat'leth, which he later described as "a more distinct, stylized weapon." After conceiving of such a prop, Moore consulted Dan Curry, who not only worked on the series full-time but was also a martial arts expert. (Star Trek: Communicator issue 114, p. 59) Curry himself recollected, "The script for 'Reunion' called for a special Klingon bladed weapon." (Star Trek: The Next Generation 365, p. 178)

Dan Curry wanted the new Klingon weapon to look relatively unique. "I looked at some of the designs that were proposed and they were wonderful, but there was a degree of familiarity about them. And I thought to myself, 'Well, you know, it's not really my job to get in people's faces about this, but because I care passionately about martial arts, and I have a strong feeling for the ergonomics of bladed weapons, let's have something that we've never seen before." (Star Trek: The Next Generation - The Continuing Mission, p. 179)

Having always been irritated that films seemed to keep portraying weapons that were meant to look appealing but actually couldn't be handled practically, Dan Curry had been envisioning a pragmatic style of weapon for a long time, thinking of it as basically a staff weapon infused with an Oriental influence. (Star Trek: The Next Generation 365, p. 178; Star Trek: The Next Generation - The Continuing Mission, p. 179) Explained Curry, "I'd been imagining a curved weapon partially influenced by Himalayan weapons like the kukri [the wickedly curved knife of the Gurkhas of Nepal, arguably the most renowned fighting knife in the world]. I was also thinking about the Chinese double ax, Chinese fighting crescents, and the Tai Chi sword. I combined elements of all those things in order to come up with an ergonomically sound weapon." (Star Trek: The Next Generation 365, p. 178) It was also important to Curry that the bat'leth could be held with either two hands or one hand. "He wanted a weapon that you could hold, you know, in a variety of ways," offered Ron Moore, "and have some interesting angles, on camera." ("Reunion" audio commentary, TNG Season 4 Blu-ray)

Dan Curry then began to put his ideas for the weapon into practice, sketching it out on a Post-it note. (Star Trek: Communicator issue 114, p. 59) A small pencil drawing matching the eventual shape of the weapon but with very minor differences, this illustration was "on the back of a Paramount phone message note," in Ron Moore's words, and was sketched in Moore's office. ("Reunion" audio commentary, TNG Season 4 Blu-ray) As such, the note ended up in his possession. (Star Trek: Communicator issue 114, p. 59; "Reunion" audio commentary, TNG Season 4 Blu-ray) Once at his own home, Curry crafted a foam-core mock-up of how he envisioned the weapon. He proceeded by showing this item to Executive Producer Rick Berman. (Star Trek: The Next Generation - The Continuing Mission, p. 179) The foam-core version of Curry's design was an admittedly flimsy prototype but was granted approval. "And Rick liked it," Curry recalled. (Star Trek: The Next Generation 365, p. 178)

The final draft of the "Reunion" script described the weapon by saying, "It is [a] semi-circular curved blade that branches to four points. It is about three feet wide. There is a terrible beauty about the blade [...] The bat'telh is held by two handles on the mid-exterior of the blade [...] The bat'telh can be used as either shield or sword." [7]

The stage directions in the script of DS9: "Blood Oath" described the bat'leth in a similar way to the script of "Reunion": "A semicircular curved blade which branches to four points. About three feet wide. It is held by two handles on the mid-exterior of the blade. It can be used as either a shield or a sword – see TNG episode 'The Reunion'". (Star Trek: Deep Space Nine Companion - A Series Guide and Script Library)

During at least one production meeting, Dan Curry became extremely animated with demonstrating how the bat'leth could be held, swung and used to disembowel someone. Michael Okuda, who was another of the meeting's participants, noted with a laugh, "We were all a little taken aback." ("Reunion" audio commentary, TNG Season 4 Blu-ray) Even so, Curry not only designed the bat'leth but also helped develop the intricate moves performed in its use. (Star Trek: The Next Generation 365, p. 178) Director and Elim Garak actor Andrew Robinson noted, "Dan is the bat'leth specialist." (Star Trek: Deep Space Nine Companion, p. 377)


At the time of its creation, nobody knew that the bat'leth was to later become a type of symbol for the Klingon species. (Star Trek: The Next Generation 365, p. 178) Over the years between its introduction in "Reunion" and its appearance in Star Trek Into Darkness, however, the bat'leth has become very well established. "There's a lot of history about the Bat'leth," commented Andrew Siegel. "It's a prop that Trekkies really like." (Star Trek Magazine issue 173, p. 79) With a smile, Dan Curry observed, "Now you seldom see a picture of a Klingon without a bat'leth in his hands." (Star Trek: The Next Generation 365, p. 178)

For DS9 Season 4 premiere "The Way of the Warrior", Jadzia Dax actress Terry Farrell learned how to use a bat'leth prop, which she didn't find difficult. "I thought it was great," she enthused. "In fact, I wish I would have gotten to do more of it!" More opportunities for Farrell to use a bat'leth were given to her later in the fourth season and onward. (Star Trek: Deep Space Nine - The Official Poster Magazine, No. 1)

After Quark actor Armin Shimerman trained with Dan Curry for a fight sequence in DS9 Season 5 episode "Looking for par'Mach in All the Wrong Places", the bat'leth became useful for Shimerman rehearsing the scene. "I borrowed a bat'leth," he said, "took it home for ten days, and worked on the maneuvers that he'd practiced with me [....] I got pretty good with the bat'leth, actually." Because Worf puppeteers Quark while the Ferengi is using the Klingon weapon, Shimerman even hired a mime artist to help him in his practicing with the prop. "I [...] worked with him on how to make it look as though the bat'leth had a mind of its own," concluded Shimerman. (Star Trek: Deep Space Nine Companion, p. 377)

In ENT: "Marauders", a bat'leth belonging to a particular Klingon crewman was scripted (as evidenced by the episode's final draft script) to be a mek'leth instead.

The bat'leth appeared in the background in the Stargate SG-1 sixth season episode "The Other Guys". John Billingsley, who played Dr. Phlox on Enterprise, also appears in the episode, as a scientist obsessed with Star Trek.

A bat'leth strap from the episode "Marauders" was sold off on the It's A Wrap! sale and auction on eBay. [8]
