Shikkar Shikkars were intricate , Force - crafted daggers made out of glass that were created and used by the Sith by the time following the Hundred - Year Darkness . Shikkars had long , elegant blades and were prized amongst the Lost Tribe of Sith on the planet Kesh for their artistic value as well as their role as weapons . They were made for one single usage — after a shikkar was used to stab someone , the hilt was broken off , leaving the blade embedded in the victim ' s body . Since the manner of death suffered by shikkar was exceptionally painful , many Sith considered it an insulting form of assassination . The weapons were crafted and employed often by members of three rival glass - crafting guilds on Kesh . Tura Sanga was famous among the Sith Tribe for crafting shikkars , and the Sith Seelah Korsin owned a shikkar that had been made by Kesh ' s native Keshiri . As the Dark Jedi Sorzus Syn noted in the " Book of Sith " , Shikkars were frequently used by Sith for assassinations . Even millennia after their invention , the weapons were still prominent — in 43 . 5 ABY , several members of the Sith strike team sent to kill the Jedi Luke Skywalker carried shikkars , including Sith apprentice Vestara Khai and her Master , Lady Olaris Rhea . Later , in 44 ABY , several shikkars were crafted specifically for decoration during the celebration that marked the Tribe ' s alliance with the dark side entity Abeloth . Description . Shikkars were daggers that were crafted from glass with the application of the Force . They had intricate , elegant blades that were up to at least ten centimeters in length — about as long as a Human forearm — and about the width of a Human finger . The blades could be straight or curved . The hilt of the weapon was also designed to be long and narrow , and at least one shikkar was colored black and white . The weapons could easily be carried hidden beneath a being ' s robes . Shikkars were valued by the Lost Tribe of Sith on the planet Kesh for their artistic virtues as much as they were for their use as weapons . The daggers were made to be used just once , and although the apparent frailty of the weapons as a whole was misleading , the point where the blade met the hilt was particularly fragile . After the weapon was used to stab someone , the hilt was twisted and snapped off , leaving the glass blade in the victim ' s body so as to cause as much pain as possible . As such , some Sith considered the use of the weapon to be particularly insulting to the target , and shikkars were frequently used as a means of getting revenge . Also , due to the fact that shikkars were made out of nothing but glass , they could pass through sensors undetected . History . Shikkars were invented and used by Sith for assassinations by the time following the Hundred - Year Darkness , which ended around 6900 BBY . The Dark Jedi Sorzus Syn , who lived in that era , made a diary entry that was included in the " Book of Sith " , a compilation of historical Sith writings , that mentioned the weapons . In 5000 BBY , a group of Sith crash - landed on the remote planet Kesh after their vessel , the " Omen " , was knocked off - course during a hyperspace jump . The survivors were stranded there , unable to call for help or rebuild their ship , and they quickly formed a new Sith Tribe . Shikkars were crafted and used by members of the Tribe ; Seelah Korsin , wife of the Tribe ' s Grand Lord , Yaru Korsin , owned a shikkar fashioned for her by the Keshiri — the natives of Kesh . By 3960 BBY , members of the Sith Tribe often used shikkars for advancement opportunities ; Sith employed the glass daggers to subtly assassinate rivals in order to ensure their own rise within the ranks of the Tribe . Sometime before 3000 BBY , one member of the Tribe tried to assassinate another Sith with his shikkar , but he had improperly constructed his sheath , and the blade fell into his ankle . The wound became infected , and the Sith died within a month . In 3000 BBY , Sith Caretaker Varner Hilts used a shikkar owned by fellow Sith Iliana Merko to cut into the command chair in the crashed " Omen " to retrieve a hidden message to the Yaru Korsin from his mother , Takara . Millennia later , in 41 ABY , shikkars were still owned by several members of the Lost Tribe , who considered them to be noble weapons . By that time , shikkars were commonly utilized by the members of the three Sith guilds that held an oligopoly on the profession of sculpting glass in the Kesh capital city of Tahv . Those guilds crafted shikkars and other valuable objects out of glass formed from the planet ' s lavender sands . Members of the guilds often used their shikkars in attempts to assassinate rival guild members ; to counter such attacks , the guilds began employing bodyguards for protection . When a Sith strike team was sent to kill Jedi Grand Master Luke Skywalker in 43 . 5 ABY , several of its members carried shikkars . During the strike team ' s battle with the Jedi at Sinkhole Station , a space station in the Maw , Master Yuvar Xal initiated a coup to take over command of the team from Lady Olaris Rhea . However , Rhea ' s apprentice , Vestara Khai , used her shikkar to kill Xal , throwing it into his abdomen and using the Force to break off the hilt . Later , when Rhea and Khai dueled with Skywalker , Rhea struck at the Jedi with her lightsaber while simultaneously using the Force to attack him with her shikkar . The blade was strong enough to rip a hole in Skywalker ' s combat vac suit before it snapped . The strike team failed to kill Skywalker , however , and Khai was the only Sith to survive the mission . Khai ' s father , the Sith Saber Gavar Khai , owned a full personal collection of shikkars on Kesh . In 44 ABY , he presented one of his shikkars to Vestara in the hope that she would be able to use it to kill either Skywalker or his son , Jedi Knight Ben Skywalker . The shikkar that he gave to her had been fashioned by the Force - sensitive Tura Sanga , who was an exceptionally famous shikkar - craftsman and whose style of shikkars was decidedly unique . Gavar Khai attempted to kill the elder Skywalker with a shikkar when a duel broke out at the Pool of Knowledge Force nexus , but the attempt failed . Later , when the dark side entity Abeloth proposed an alliance with the Sith Tribe to defeat their mutual enemy , the Jedi , she was invited to Tahv . There , several shikkars were created specifically for the celebration that was held in her honor . However , Abeloth betrayed the Sith and attacked the capital , destroying buildings , killing thousands of residents , and using her Force powers to send shikkars flying through the city with the intent of causing harm . The Jedi later embarked on a mission to defeat the Sith on the galactic capital planet Coruscant ; during the mission , Vestara Khai stabbed Sith Master Ruku Myal with his own shikkar .
