Andúril

The sword Andúril is wielded by Aragorn son of Arathorn the heir of Isildur and king of Gondor. It does not have a crafting recipe. In the future it can be obtained in quests but now it can be obtained only via creative.

History:
Andúril was forged by the Elves of Rivendell (before the Fellowship of the Ring departed on the Quest of the Ring) from the shards of Narsil, which were precedently carried by the ranger Strider (Aragorn II son of Arathorn II, 16th and last Chieftain of the Dúnedain, future High King Elessar of Arnor and Gondor). He used the Sword Reforged as proof of his heritage on several occasions - such when he, Legolas and Gimli were confronted by Éomer (Chief Marshal of the Mark and future King of Rohan), as well as when the Aragorn and company confronted the shades of the Paths of the Dead.

The original sword Narsil, from who’s shards Andúril was forged, was itself forged by the great Dwarven smith Telchar of Nogrod in the Blue Mountains - from whom it was evidently eventually passed to the Kings of Númenor, as after the sinking of Númenor Elendil (first King of [all or any of the] the Dúnedain and of Arnor and Gondor) arrived in Middle-Earth with it in his possession. When Elendil was killed in the War of the Last Alliance and his son Isildur reached for Narsil, it was broken by the Dark Lord Sauron, yet was still used by Isildur to cut the ring from Sauron’s finger and so destroy his physical form and injure his spirit. Momentarily before Isildur’s own death at the Disaster of the Gladden Fields, the Shards of Narsil were rescued by his esquire Ohtar, who took them to Rivendell. There, they were claimed by Isildur’s son Valandil, and from him passed they to the rest of the heirs of the throne of Arnor (the future Chieftains of the Dúnedain) of whom Aragorn II and Arathorn II were. Both Anduril and Narsil were and are regarded as the sword of the king of men.
