It was respected by the Mandalorians as a symbol for the leadership of House Vizsla, and later Death Watch. According to the ways of the Nite Owls and the Mandalorian fleet, the ruler of Mandalore must possess the Darksaber.
An ancient lightsaber that serves as a powerful symbol of leadership to the Mandalorians, the Darksaber is a unique weapon with a black-energy blade lined with a crackling white edge.
Because the Darksaber's sentience intertwined its fate with the rulers of Mandalore, Mando's rejection of that role meant that their wills could never align. That's why he has so much trouble wielding the weapon: it doesn't want to be wielded by a selfish bounty hunter who doesn't care about Mandalore.
Ironically, the more Din Djarin uses the Darksaber the greater those issues likely become, because he knows this weapon should be used by the ruler of the Mandalorians - and he doesn't feel up to that task.
Dave Filoni, a Lucasfilm creative, explains that the Darksaber is not necessarily more powerful than a typical lightsaber and its old age could make it less powerful. The main difference between the Darksaber and lightsaber is its design, with the flat blade of energy being a unique "Mandalorian twist."
Why The Darksaber Is WAY More Dangerous Than Any Other Lightsaber
Has a Jedi ever wielded the Darksaber?
The very first owner of the Darksaber was the man who created it, Tarre Vizsla. Very little is canonically known about Tarre Vizsla, other than the fact he lived during the Old Republic era and was, at that time, the only Mandalorian to have ever been accepted as a Jedi.
In "Trials of the Darksaber," Kanan told Sabine Wren that when someone wields a lightsaber, his or her thoughts fuel the blade's energy. So, if they were off-balance or conflicted, then the blade would feel heavy. The Armorer said as much when she told Din that he was fighting against the blade.
Din Djarin gave up the Darksaber so that Bo-Katan could rule Mandalore -- but not because he wasn't worthy of wielding it. Lightsabers are so deeply embedded in pop culture that even the most casual Star Wars fan knows the weapons' basics.
Star Wars: The Clone Wars revealed the Darksaber can be wielded by a non-Mandalorian, who therefore has a claim to become the rightful ruler of all Mandalorian clans while bypassing their initiation rituals. This was proved by Darth Maul, who defeated Pre Vizsla in battle and claimed the Darksaber.
The episode saw Bo-Katan Kryze wielding the Darksaber as she fought Moff Gideon, which ended with (final spoiler warning) the Mandalorian artefact being crushed in the fist of Gideon's fancy new Dark trooper armour.
When he passes away, it gets passed down through inheritance to his son, Luke Skywalker. So technically. the Darksaber belongs to Luke Skywalker rightfully.
The reason there is only one is because the kyber crystal inside of the lightsaber took on the black color due to the contradiction of being both a Mandalorian and a Jedi at the same time, seeing as both groups hated each other (or in the Jedi's case, greatly disliked).
In a galaxy filled with lightsabers of various colours, the Darksaber stands out as the rarest lightsaber colour, shrouded in mystery and steeped in history. Created by the first Mandalorian Jedi, it has passed through the hands of warriors, terrorists, and heroes, leaving an indelible mark on the Star Wars universe.
At the time of The Mandalorian story, it is pretty clear that Moff Gideon is not a Sith Lord even though he has the Darksaber in his possession nor does he have any links to the Jedi. Moff Gideon is nothing more than one of the Empire's existing bad guys who officially worked for the Imperial Security Bureau.
Vizsla made the mistake of betraying Maul, who returned the favor by killing him in a lightsaber duel. This made Darth Maul the rightful owner of the Darksaber. Maul, however, soon lost the Darksaber when Darth Sidious defeated him in combat and sent him away to prison on Stygeon Prime.
Bo-Katan lost scores of loyal soldiers in Gideon's surprise attack, and now the Darksaber itself has been destroyed. Even if the Armorer could have repaired the hilt after it was crushed in Gideon's super-strong fist, we assume the massive explosion from the falling ship obliterated what was left.
Answer: Yes, the Darksaber contains a Kyber crystal, which is its power source. Like all lightsabers, the Kyber crystal within the Darksaber focuses the weapon's energy on producing its blade.
Like a traditional lightsaber, it can block another lightsaber's blow. However, the hilt of the Darksaber is constructed of beskar. Despite that, it cannot cut through beskar. However, it can begin to melt the alloy, turning it red with heat.
After Sabine observed that the Darksaber is deceptively heavy, Kanan explained that energy follows through the blade, with the wielder directing its current of power. The wielder's thoughts and actions flow into the Darksaber to fuel this energy, affecting the weight.
It's already been established that the hilt of the Darksaber is crafted from beskar, so it's also likely that Tarre Vizsla used beskar inside the Darksaber as well. Like kyber, beskar could theoretically conduct energy from the blade's power cell into the emitter.
The color of a lightsaber's blade is decided by the kyber crystal contained within it; Sith wield crimson blades because they have bent the crystal to the dark side. The Darksaber is Star Wars' only black lightsaber.
Naturally, the same rules of the Darksaber apply to Bo-Katan, though she wields the weapon with ease against Djarin's captor. This is presumably because Bo-Katan possesses much greater confidence about her identity, even when she has lost faith in her mission to restore Mandalore.
According to the runaway Jedi, the Darksaber is considerably harder to wield than your average lightsaber. Jarrus says, "Energy constantly flows through the crystal. You're not fighting with a simple blade as much as you are directing a current of power. Your thoughts, your actions, they become energy.
Tarre Vizsla must have had an incredibly unique and powerful relationship to the Force for his lightsaber to take on the dark color, and it may have even contributed to its unique shape as well. The Darksaber also has several unique quirks that aren't seen with other lightsabers.
