Tera Sinube ' s lightsaber Tera Sinube ' s lightsaber was the personal lightsaber of the Cosian Jedi Master Tera Sinube , which was a cane lightsaber — a specialized device that was also a walking stick — due to his advanced age . Designed to be as much of a weapon as a reinforcement for his gnarled frame , Sinube only exposed the duplicity of his stick when armed combat was the necessary course of action . When needed , he would activate his lightsaber by separating the handle and collar from the shaft to produce a light blue beam of plasma . Sinube used his saber during the Clone Wars , a conflict that pitted the Republic against the Separatists , when he wielded it to great effect against the thieving Terrelian Jango Jumper Cassie Cryar . Description . Due to his age , Jedi Master Tera Sinube utilized a cane lightsaber , a specialized device that was both a crutch and a lightsaber in one . The handle of Sinube ' s lightsaber was T - shaped , and along with a collar , connecting the weapon to the shaft . Powered by a kyber crystal , the saber emitted a very light blue plasma . The intricately carved collar was connected to a shaft that finished with an enlarged ferrule , the size of which provided increased stability and support for the aged Cosian as he moved about . The rounded ferrule had a flat bottom and four symmetrically placed protrusions . In its completed form , the lightsaber was roughly half the height of Master Sinube . As Force - users advanced in age and became less able to sustain themselves physically , they made use of devices to help lessen the burden on their bodies . In situations where a peaceful approach was less practical and therefore required more aggressive negotiations , some chose to abandon their walking sticks entirely in favor of lightsabers . Master Sinube , however , fought with both his cane and lightsaber , as they were one and the same . He surprised his opponents , who attacked Sinube as though he was unarmed , by separating the lightsaber from his cane and wielding both parts in concert , with the lightsaber in place as the bladed weapon while the ferrule at the end of the shaft — which Sinube brandished in a reverse grip — served as an effective bludgeon . History . Jedi investigator Tera Sinube ' s lightsaber was crafted some time before the battle of Saleucami , a conflict during the pan - galactic Clone Wars which pitted the Galactic Republic against the Separatist Alliance . Sinube utilized his lightsaber while on a quest to find the missing lightsaber of Jedi Padawan Ahsoka Tano in the year 21 BBY . The two Jedi traversed the lower levels of the galactic capital world of Coruscant and eventually found the Terrelian Jango Jumper Cassie Cryar in possession of Tano ' s weapon . They were forced to give chase and were able to eventually corner Cryar on a train . When Cryar attempted to attack Sinube with Tano ' s lightsaber , the Cosian Jedi Master separated the shaft from the handle and collar , from which he then produced his lightsaber blade . Wielding shaft and saber in either hand , Sinube proceeded to battle Cryar with both parts , parrying several of her ripostes with his lightsaber before using the cane extension like a cudgel and striking Cryar in the head with it . The Jedi then retrieved the lightsaber from Cryar , letting the unconscious thief get arrested by the police droids . Later in the Clone Wars , in the year 19 BBY , Sinube was overseeing a group of younglings training in the courtyard of the Jedi Temple when Jedi Knight Anakin Skywalker and Padawan Barriss Offee ' s duel spilled out of the Temple corridors . Sinube drew his lightsaber in defense of the younglings and watched as Skywalker subdued the fallen Jedi . Behind the scenes .
