The sword forged from the shards of Narsil for Aragorn is Andúril.
Narsil was the sword of Elendil, the founder of Arnor and Gondor. It broke when Elendil fell during the final alliance against Sauron, but its shards remained a symbol of the royal line. Elendil’s son Isildur used the broken blade to cut the One Ring from Sauron’s hand.
In Rivendell, the shards are reforged for Aragorn, Isildur’s heir, and the sword receives the name Andúril, meaning “Flame of the West.” The reforged weapon represents Aragorn’s acceptance of his ancestry and his claim to leadership. Glamdring belonged to the Elven king Turgon, Orcrist was a famous Goblin-cleaver, and Sting was Bilbo’s small Elvish blade.
