Jedi Temple Guards and Jedi Brutes also wielded double-bladed lightsabers, with the former having ones that produced yellow blades. The notorious cyborg Jedi hunter General Grievous also possessed a double-bladed lightsaber; specifically the weapon carried by Darth Zannah.
Grand Master Satele Shan used a double-bladed lightsaber during the Old Republic, and Pong Krell used two of them in The Clone Wars. So, in short, the Jedi weren't prohibited from using double-bladed lightsabers, but it was frowned upon because it looked like a power grab, rather than an attempt to serve the galaxy.
Early Days of the Double Blade
The dual lightsaber is believed to have been invented by the Dark Lords of the Old Sith Empire. Its first notable appearance was in the Great Sith War when Exar Kun, the one-time Jedi Knight, used it to lead his Brotherhood of the Sith into battle.
Why didn't more Jedi use double-bladed lightsabers? The Jedi disliked the idea of using a second blade on a lightsaber. A second blade for the idea of inflicting more damage was very much a Sith idea and few Jedi were interested in using any Sith ideas.
The Rise of Skywalker novelization revealed that Rey was planning to build a double-bladed lightsaber early on in her training, but that idea changed after the Dark Rey experience. This vision was a dark manifestation of herself, and as such, it appeared with a double-bladed lightsaber, reflecting Rey's plans.
The crossguard blades allow Ren's saber to operate safely – his weapon is constructed around a dangerously flawed kyber crystal, which would be overloaded if not for the lateral plasma vents that create the quillons.
The Story of Kylo Ren's Lightsaber Hilt
Ren's crossguard lightsaber is far from unique. Sporting two secondary blades (quillons) protruding from the top of the hilt at 90-degree angles, it is actually based on a design that was created thousands of years before his birth.
Inside, two lightsabers have been laid to rest. One was Kenobi's during his time as a Jedi Master; the other belonged to his apprentice, Anakin Skywalker, before his fall to the dark side.
Of course, Star Wars lore dictates a level of responsibility in wielding one. However, it's seldom been discussed as to who can actually use a lightsaber. Indeed, they've been used by the Jedi, the Sith, and individuals throughout the diversity of Star Wars media.
Of all the ancient lightsabers, few have played as major a role in modern Star Wars canon as the Darksaber. The blade was crafted by the first Mandalorian Jedi, Tarre Vizsla, in 1032 BBY. It is unique for its black, narrow blade, which responds to the emotional state of those who wield it.
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.
2) Who is the only non Jedi in the original Star Wars trilogy to use a lightsaber? Han Solo uses Luke's lightsaber to cut open the tauntaun's belly in The Empire Strikes Back.
In the years before the Battle of Yavin, Ahsoka Tano used two white lightsabers as her personal weapons.
The double-blade means you've got twice as much laser sword to work with. It's much better at blocking attacks (including blaster bolts) coming in from multiple angles. It doesn't seem to deal as much damage to a single target, but you're more likely to hit multiple enemies with each swing.
Kestis combined the lightsabers of Jaro Tapal and Cere Junda to forge his own double-bladed weapon. Spurred on by his newfound resolve, Kestis placed the two halves of the crystal on a base of ice and began forging a new lightsaber.
The Sith apprentice Darth Maul wielded a double-bladed lightsaber made by joining two hilts together end-to-end. Maul's dexterity and extensive training allowed him to use his weapon as a single-bladed saber, or to activate both crimson blades and fight multiple opponents at once.
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.
Jedi Knights are forbidden from having any kind of attachment, romantic or otherwise. This is one of the reasons why their training starts when they're very young, as they are not meant to stay close to their families.
A crystal embodies the Jedi as the heart of the lightsaber, and pure kyber has no color until it's bonded to the Force user. This process likely resulted in Rey Skywalker's lightsaber being yellow.
Whereas Obi-Wan buried both Anakin's and his own lightsaber, Rey buried Luke's and Leia's while creating a new one for herself. She lived in a different era, when Jedi light was re-emerging and she had nothing to fear. Her decision to bury Luke and Leia's lightsabers was an attempt to give them a new legacy.
Rey's lightsaber was a yellow-bladed lightsaber that was constructed by the Jedi Rey Skywalker following the First Order-Resistance War.
Even though Kylo Ren uses a red lightsaber, harnesses the dark side of the Force, and wears a cape, he is not a Sith. Because of that, he can never hold the title of Darth. Instead, he was just a chaotic mess of the dark side (until he eventually found his way back to the light).
Without a doubt, the most notable Jedi with a purple saber is Mace Windu, portrayed in the prequel trilogy by Samuel L. Jackson. Audiences first got a glimpse of the unusual blade in Episode II: Attack of the Clones, making Windu the coolest Jedi in one cinematic moment.
Kylo Ren's lightsaber had a cracked kyber crystal, which generated an unstable blade. The excess power was vented out the sides, thus creating a crossguard-like design. The most important and prestigious vessels of the First Order had weapons upgraded with kyber crystals from some secret source in the Unknown Regions.
