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 Darksaber was an ancient black-bladed lightsaber. It had a unique blade that was shorter than that of most lightsabers, and shaped like a traditional sword. Its overall profile was distinctly Mandalorian with an angular pommel, hand guard, and slit-shaped blade emitter, all of which was made out of beskar.
The Darksaber is an extraordinary weapon with a Kyber crystal at its core, just like traditional lightsabers. Its unique design, history, and connection to its wielder set it apart as a symbol of power and leadership among the Mandalorian people.
According to the officials, a pure Beskar armor can resist a temperature of 30000°C. A lightsaber's temperature can only go up to 25000°C. That means one direct hit of the lightsaber cannot cut through the Beskar.
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.
The black lightsaber, or Darksaber to give it its proper name, is one of the rarest lightsabers in Star Wars canon. Despite its rarity in canon, anyone who has seen the second season of The Mandalorian is likely to be familiar with the Darksaber.
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."
Obsidian in the armor supercharged Vader's dark side power, turning anger into a power source. The Empire couldn't use beskar in the armor due to a lack of knowledge on forging the Mandalorian alloy.
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.
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.
Like all lightsabers, the Kyber crystal within the Darksaber focuses the weapon's energy on producing its blade. However, the Darksaber's crystal and the gun have unique properties, resulting in their black coloration and distinct blade characteristics.
It is important to understand that the Darksaber is a unique weapon, not a style that can be imitated. That accounts for its rarity in the Star Wars universe—there is literally only one in existence. Tradition holds that the Darksaber can be won only by besting its owner in combat.
Ahsoka's white lightsabers first appeared in the TV episode "Fire Across the Galaxy", the season one finale for Star Wars Rebels. According to Dave Filoni, one of the show's creators, the lightsaber blades are white to reflect her non-affiliation with the Jedi or Sith.
Jango Fett's armor was partly made of durasteel, and General Grievous had some parts of his body made of this material. Darth Vader's armor was mostly made of durasteel, as was Boba Fett's before he upgraded during the Second Galactic Civil War to armor made of beskar.
The helmet, which was created using an alloy of durasteel, plasteel, and obsidian, had a sloped design for its sides and back similar to that of the helmets on ancient Sith armor. The helmet created Vader's menacing growl due to his natural voice being very weak from vocal-cord damage.
All of that goes to show that Mando not being able to lift the Darksaber has nothing to do with how he acquired the blade or his failing the Creed. Accordingly, the best explanation is still that the Darksaber doesn't personally approve of Mando.
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.
Still, Bo-Katan is the better wielder. In The Mandalorian season 3, episode 2, Din struggles to use the Darksaber against Alamite raiders. Bo-Katan later uses the Darksaber against a frightening crustacean cyborg scavenger, and she has no trouble wielding the blade and slaying the foe.
Beskar is supposedly resistant or proof to lightsabers, but is it strong enough to prevent itself from being crushed by someone using the force? Beskar is an extremely tough metal. It's unable to be affected by blaster bolts and even lightsaber strikes.
Could be any number of reasons ranging from faulty surge protection anodes, to Starkiller and Palpatine having vastly different current frequencies and voltages in their force lightening.
Affiliation. Boba Fett's armor was a suit of customized Mandalorian armor worn by Boba Fett, a human clone who became a bounty hunter. The armor was made from beskar.
To be clear, Grogu is not a younger version of Yoda since "The Mandalorian" is set after "Return of the Jedi," in which Yoda (played by Frank Oz) died. They are, however, of the same species — but that species has not yet been revealed. There are more similarities between Yoda and Grogu than just looks.
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.
