The First Blade was originally crafted by a Je'daii called the Weapon Master on Tython. During the Force Wars, Jedi High Council member Rajivari searched to retrieve the First Blade. He proved worthy of it, and was permitted to take the hilt.
The earliest known functional lightsabers were called the First Blade, built on Tython and the Ryo Fortress on The planet Shikaakwa. Prior to this news, the items were created in the Force Wars by an unknown Je'daii Master with the help of the Shikaakwa people, the title would known only as the Weapon Master.
The earliest lightsabers that can properly be called as such were designed by the Jedi, but were eventually taken up by the Sith and the Dark Jedi as well. Like later lightsabers, these weapons used a focusing crystal in the hilt to generate the blade.
The original lightsaber hilts were cobbled together from literal spare parts, with antique cameras providing most of the raw material. Obi-Wan Kenobi's, Darth Vader's, and Luke's (well, Anakin's) sabers were all made from flash handles—Luke's and Obi-Wan's from an antique Graflex, and Vader's from an MPP Microflash.
Originally, Lucas and the crew wanted to give the weapons a glow that could be seen on camera. The blades of the early lightsabers were three-sided wooden dowels that were coated with retroreflectors, much like the material that is used to make street signs visible.
Anakin Skywalker carried this blue-bladed Jedi weapon throughout the Clone Wars. After dueling his former apprentice on Mustafar, Obi-Wan Kenobi took Anakin's lightsaber and kept it on Tatooine for nearly two decades. He gave it to Luke Skywalker, who lost it when Darth Vader struck off his son's hand in Cloud City.
Black is the rarest lightsaber color in the world of Star Wars. For a while, the only known black lightsaber was the Darksaber, forged a thousand years ago and owned by a Mandalorian Jedi.
Form I, also known as Shii-Cho, The Way of the Sarlacc, or The Determination Form, was the oldest and most rudimentary form of lightsaber combat developed by the Jedi Order and was taught to all members of the Jedi Order.
The Prime Jedi was an individual who became the first Jedi to ever use the Force. The Prime Jedi was also the founder of the Jedi Order. The Prime Jedi established the Order on the planet Ahch-To, around 25,025 BBY.
Ajunta Pall was a male Human Jedi Master and the leader of the Dark Jedi that was exiled from the Jedi Order and the Galactic Republic following the Hundred-Year Darkness. Upon his arrival on Korriban, he became the first Dark Lord of the Sith.
Kylo Ren's lightsaber was a crossguard lightsaber wielded by Kylo Ren, Supreme Leader of the First Order and master of the Knights of Ren. The lightsaber was previously Ben Solo's lightsaber, constructed by Ren in his life as Ben Solo while training as a Jedi Padawan under his uncle, the Jedi Master Luke Skywalker.
Yoda rarely if ever drew his lightsaber, preferring to work in more subtle ways. But the Jedi Grandmaster remained a formidable warrior, as Count Dooku and Darth Sidious discovered when they confronted Yoda in battle. Yoda's lightsaber was smaller than a standard Jedi lightsaber, befitting his shorter stature.
At the end of Star Wars: Episode IX – The Rise of Skywalker, we see that Rey has finally constructed her own lightsaber, having reached the end of a long journey and completed training with both Lukeand Leia.
At the end of the film, Rey returns to Luke's home on Tatooine, where she buries Luke and Leia's lightsabers, then reveals her own—decked out with a golden-yellow blade, a hilt that looks like it might've been crafted from her staff, and a cigarette-lighter-looking switch that turns it on.
When Obi-Wan Kenobi's blue saber clashed against Darth Vader's red in the first film, each color was a representation of their innermost selves, a legend which would take further shape and definition as the saga continued. Originally, it was a pretty simple code to crack. Blue was good. Red was evil.
The weakest and most harmless type of lightsaber is the one that has been “baby-proofed”: the training lightsabers. As the name implies, this type of lightsaber is only utilized in the context of training very young Jedi to one day become Jedi Masters.
History. Asajj Ventress and Ahsoka Tano were two notable practitioners of Jar'Kai, preferring to use two lightsabers as opposed to one. The cyborg General Grievous had been outfitted with arms that could split in half, enabling him to choose between holding two lightsabers or four lightsabers.
During his years as a Jedi, Obi-Wan Kenobi fought with three lightsabers.
As a Padawan, Ahsoka Tano used a green-bladed lightsaber, often wielding it in a non-standard reverse grip. Under the tutelage of Anakin Skywalker, Ahsoka became a skilled duelist, and built a second green-bladed lightsaber with a shorter, shoto-style blade.
Interestingly, Yoda's first lightsaber was also green. It seems that, unlike Luke Skywalker or Ahsoka Tano, Yoda used the same lightsaber color throughout his entire Jedi career.
Lightsaber Colors Used to Matter
A brief who's who of users with blue lightsabers includes Obi-Wan Kenobi, Luke Skywalker, Anakin Skywalker (Hayden Christensen, pre-youngling slayer), Shaak Ti, and Count Dooku (Christopher Lee, pre-dark side/ass handed to him by Yoda).
