Darth Sidious ' s lightsabers Darth Sidious ' s lightsabers were the pair of nearly identical personal electrum - finish lightsaber s of Darth Sidious , built during his apprenticeship under Darth Plagueis . Sidious rarely used his weapons — only doing so when absolutely necessary — as they would have immediately identified him as a Sith Lord . Instead , he preferred to exercise his powers of manipulation and used servants to carry out his hidden agenda . Specifications . Darth Sidious had discerning tastes , which was reflected in his lightsaber s . They were constructed from nearly indestructible phrik with a flat aurodium blade emitter , and all finished with electrum . The weapons utilized a Kyber crystal at their cores . While both were originally identical , one of them was later retrofitted with an unknown black material . One of the weapons was normally hidden inside a neuranium sculpture that was displayed on the desk of his office within the Senate Office Building on Coruscant . History . In 19 BBY , Darth Sidious carried both of these lightsabers when he secretly traveled to Mandalore to confront Darth Maul and his apprentice Savage Opress . He wielded both weapons in the ensuing duel , separating the pair and effortlessly dispatching and killing Opress . Maul , using two lightsabers of his own , proved a much tougher opponent and held his own for a while longer . Sidious eventually dispensed with swordplay and defeated Maul with the Force , subduing him with a combination of telekinesis and Force lightning . Near the end of the Clone Wars , Palpatine fought against Jedi Masters Mace Windu , Kit Fisto , Saesee Tiin and Agen Kolar . He slew Kolar , Tinn and Fisto easily , but had an extended confrontation with Windu . The Jedi guided the battle towards the bay window of Palpatine ' s office and out onto the wind - blown ledge outside . Windu disarmed the Sith Lord with a surgically precise kick to the face , throwing Palpatine off - balance and causing the Sith Lord to drop his lightsaber as he flailed for purchase . The lightsaber fell out the window into the seemingly bottomless streets and alleyways of Coruscant below just before Skywalker showed up . Consequentially , it also forced him to rely only on one lightsaber . After Obi - Wan Kenobi and Yoda realized what had happened , Yoda went to face the Emperor personally at the Senate Building , while Kenobi headed off to kill Darth Vader . Yoda surprised Palpatine , who told him that his arrogance blinded him and that his apprentice would be more powerful than both of them . Yoda answered Palpatine that his faith in Vader was a mistake along with his faith in the dark side . Yoda dueled Sidious , who had already retrieved his other weapon and placed it in his sleeve . The duel brought them to the Galactic Senate Chamber , the heart of the Senate . Sidious hurled Senate pods at Yoda , and the effort to avoid them exhausted the Jedi Master . Sidious then blasted Yoda with Force lightning , but with the last of his strength the Jedi Master repelled it enough to send both himself and Sidious over the pod ' s edge . Palpatine was able to hold on to a senate pod , while Yoda fell to the senate floor , leaving only his cloak . With Bail Organa ' s help , Yoda fled the Senate Building and would go into exile . Darth Sidious would once again use his lightsaber and fought alongside his apprentice against a swarm of lylek s on the planet Ryloth .
