Sith sword Sith swords , or Sith warblades , were melee weapons used by the Sith in the days of the Sith Empire , from 6900 BBY to approximately 5000 BBY . Though similar to the bladed weapons utilized by the ancient Jedi , Sith swords were distinguished from Jedi katanas by their fundamental nature — both powered by and empowering the dark side of the Force . Description . Sith swords were constructed through various metallurgical and arcane means , transmuting base metals into an alchemical alloy possessing an unusual affinity for dark side energies . The rare metallic compounds used in its construction could result in blades varying in weight from 3 kilograms up to 6 . 5 kilograms , a blade far heavier than its 1 . 4 meter length would indicate . It often required great strength of body as well as in the Force to successfully wield the weapon and make it as dangerous as a lightsaber . In fact , the alchemical alterations allowed the Sith sword to block incoming lightsaber attacks , as well as deflect and redirect blaster bolts in much the same way a lightsaber did . A user skilled in the dark side could alter the weapon ' s molecular structure , making it stronger and sharper , and reverse its magnetic polarity , turning it into a high - temperature superconductor that could deflect blaster bolts and other particle weapons as if magnetically sealed . The rare ores used in its construction resisted lightsabers in much the same manner as cortosis and Phrik alloy , while its polished surface reflected laser beams and other coherent light weapons like a mirror . But perhaps most significantly , the weapon served as a focus for the dark energies of its wielder , amplifying their power and refining their control until they became a walking nexus of dark side power . The weapon ' s magnetic properties , combined with its attraction to the dark side of the Force , caused it to react unusually to discharges of Force lightning ; The blade would attract and absorb the energy , storing it like an electric capacitor until the blade made contact with a substantial physical object , whereupon the amplified electrical energy was discharged — to an extremely devastating effect . History . The origin of the first Sith sword ever constructed is unknown , but it is possible it may have predated the earliest lightsabers . Developed by the ancient Sith , it was adopted by the " Jen ' jidai " following their arrival on Korriban . The Sith ' s native martial traditions were absorbed , blending with the exiled Jedi ' s forms of lightsaber combat to create a powerful hybrid — much as the Dark Jedi would do with the Sith race as a whole upon seizing the mantles of Sith Lords . Quite a few Sith Lords , including the Dark Lords Ajunta Pall , Marka Ragnos , Naga Sadow and Ludo Kressh used Sith swords rather than lightsabers — either for tradition , or because they preferred the more visceral feeling of sword cutting through flesh . After the fall of the Old Sith Empire , the majority of the Sith abandoned Sith swords in favor of the more effective lightsabers . Another pair of Sith swords was a legacy passed to King Ommin of Onderon from his family , which could possibly trace back to Freedon Nadd himself . The pair was later passed to Satal Keto and his cousin , Aleema . Under Darth Revan and Darth Malak ' s rule , the Sith developed the Sith Tremor Sword , used by Dark Jedi and Sith troopers alike . Malak was also rumored to have in his possession a powerful Sith sword recovered from Korriban , although he rarely used it in combat . Ludo Kressh ' s War Sword was a double - bladed sword , and therefore very dangerous to wield . Some say it was cursed , corrupting the mind of one who would use it . It is possible that this sword was recovered by the Jedi Exile , during the events of the First Jedi Purge , sometime before the deaths of Darth Sion , Kreia and Darth Nihilus . Interestingly , Sith Elite Warbot s , a type of battle droid produced by the ancient Sith , were equipped with a Sith sword as their main weapon . The Emperor ' s Wrath ( Galactic War ) was sent to receive a Sith sword by Tremel who ' s daughter had taken much longer to gain one . In the New Sith Empire , the Dark Underlord wielded a pair of Sith swords . Slaver Phylus Mon provided his Force - sensitive Wampa , Ku - Kak , with a Sith sword at some point before 22 BBY . Ku - Kak , a user of the dark side , used the sword as his weapon of choice . The statues on Dromund Kaas held swords resembling Sith swords . Sith swords were last seen in 14 ABY when Tavion Axmis , possessed by the Force ghost of Marka Ragnos , unleashed the hidden sword inside the Scepter of Ragnos against Jaden Korr . The Sith sword glowed with dark side energy as Marka Ragnos battled Jaden Korr , ending with the defeat of Marka Ragnos and the destruction of the sword and the Scepter of Ragnos . Any remaining examples of Sith swords in the greater Galaxy persist as mere historical curiosities — archaic relics of a dead civilization and their extinct culture .
