Anakin Skywalker's lightsabers

Anakin Skywalker's third lightsaber
Jedi Knight Anakin Skywalker's lightsaber — technically his third one — was the longest lasting lightsaber in the entire Star Wars Saga [from the end of Episode II all the way to Episode IX], lasting all the way through the Galactic Civil War and its aftermath before being destroyed amidst the conflict between the First Order, and the republican Resistance. First constructed by Anakin Skywalker himself when he reached the rank of Initiate (after completing the trials), and lost his previous lightsaber right before the battle of Geonosis ;

Anakin crafted this one soon after, which he used thoughout the whole Clone Wars to fight opponents such as Asajj Ventress, Count Dooku on multiple occasions, General Grievous and his Magnaguards aboard the Invisible Hand upon freeing Supreme Chancellor Palpatine as a Jedi, then Mace Windu, Jocasta Nu, Cin Drallig, the whole Jedi Temple on Coruscant, Nute Gunray and the other Separatist leaders as a Sith, before finally losing his weapon along with several limbs when failing to kill his Jedi Master, Obi-Wan Kenobi, on Mustafar. Anakin saw his former Master take his lightsaber before leaving him to die on the lava rocks of the fiercely active planet.

Vader had lost everything Skywalker longed to preserve.

From Father to Son
Obi-Wan then passed this lightsaber on to Anakin's own son, Luke Skywalker, on Tatooine, when 19 years after Mustafar [Episode IV] the now old Jedi Master was called back to intergalactic action. It is known that Luke made his first movements and took his first Jedi lessons from Obi-wan Kenobi during their trip to Alderaan in order to deliver R2-D2 to the Rebel Alliance, then both the droid and the help call sender herself, Princess Leia Organa. Luke quickly appeared proficient in calling for the Force to aid whatever the task at hand, and it proved most useful when delivering the proton torpedo that gave death to the first Death Star.

Luke carried his father's lightsaber throughout the Galactic Civil War, and his most notable feat with it was slicing open the inside protective panels of an imperial AT-AT by his own self during the battle of Hoth [Episode V], allowing a single well-thrown grenade to blow the massive ground war machine at its core and take it down to the ground.

Despite not being able to use it in time to save Kenobi on the first Death Star, Luke used it later against Darth Vader in multiple occasions subsequently, the last one in the Cloud City, on the planet Bespin. Vader and Luke fought throughout the service corridors of the city, with Luke showing impressive feats of Jedi abilities and skills, before Vader regained an easy victory by slicing Luke's hand off, throwing Anakin's lightsaber down a seemingly endless empty shaft into uncertainty.

Luke... Luuke...
It is unclear how the lightsaber first survived its fall on Bespin, let alone with Luke Skywalker's hand along with it !

However, one of the most bizarre and formidable enemies of Luke Skywalker post-Endor [Episode VI] was an Order 66 survivor Jedi turned mad called Jorus C'baoth. This Jedi turned madman entered somehow in possession of both hand and lightsaber, and had a clone of Luke made from the hand's cells !

Luke Skywalker, therefore, armed with his own green-bladed lightsaber, had therefore faced a clone of himself called Luuke who carried his former weapon, in lightsaber combat, just like his father did before him.

Luke defeated Luuke, while his now-girlfriend Mara Jade took the madman down. Skywalker reclaimed his father's lightsaber and shortly after, gave it to Mara Jade. What happened of both, afterwards, isn't clear.

Viva la Rey
The aftermath between Mara's loss of Anakin's saber, and Rey's claiming of it, is also unclear. But it eventually happened [Episode VII], and quickly "connected" with the orphan, for unclear reasons. Rey and her friend, Finn, alternated usage of Anakin Skywalker's lightsaber, including in a duel with aforementioned Jedi's own grandson, Ben Solo. The lightsaber was caught in a tug-of-war between Rey and Solo, but visibly traumatized by Vader's evil, the weapon chose the girl.

Rey carried on with Anakin's weapon, and its blue blade met many imperial guards before eventually finding its way into Supreme Leader Snoke [Episode VIII]. It is also during that time that the lightsaber, again taken in a tug-of-war yet no longer repulsed by Solo, suffered its hardest modification since Tatooine : it imploded in half !

It's only after the stressful news of the Emperor's resurgence [Episode IX], that the repaired lightsaber ("reforged", as it would be called for differentiation among all the versions) met its final form : Rey had re-welded, and replaced the bulky activator with a smaller one linked with leather. For the first time since half a decade, the Emperor met the lightsaber that saved him from certain death, at the hands of Mace Windu and his purple-bladed lightsaber.

Both Rey and Solo took on the formidable villain, and it took both Anakin's and Leia's weapons, as well as her lover's sacrifice, to survive the Battle of Exegol.

After successfully crafting her own lightsaber, Rey went on to the now abandoned Lars Homestead on Tatooine in order to bury both weapons into the infinite sands of the Dune Sea.
