The first lightsaber to eschew the red-blue binary, Luke's self-constructed weapon really was a thing to behold when Return of the Jedi first released in 1983.
Based in-part on the weapon wielded by Obi-Wan, Luke constructed the sabre during the final moments of his Jedi training on Tatooine, fashioning the blade itself shortly before the rescue of Han Solo from Jabba's Palace.
The moment where Luke activates the blade has to be one of the best in the franchise, solidifying his status as a Jedi Knight and one finally capable of going toe-to-toe with his father, should the opportunity arise. When it does, we're treated to one of if not the finest duel of the franchise, as Luke unleashes his full power against his father and inches dangerously close to the Dark Side in doing so.
There isn't a blade like it, and while the concept of a green lightsaber might seem like a novel one today, at the time, it was something truly special. It still is now, and the chance of seeing it again is one of the reasons why everyone's so excited for The Last Jedi.
