What is the name of the sword wielded by the hero Aragorn in the Lord of the Rings universe?

The sword wielded by Aragorn in the Lord of the Rings is called Andúril, also known as the Flame of the West. Andúril was reforged from the shards of the sword Narsil by the Elves of Rivendell and given to Aragorn by Elrond as a symbol of his rightful claim to the throne of Gondor. The sword is described as having a blade that shines like the sun and a hilt adorned with the heraldry of Gondor and Rohan.

Andúril played a significant role in the story of the Lord of the Rings, as it was used by Aragorn in many of his heroic battles and was a symbol of hope to the people of Middle-earth.

Andúril was originally wielded by Isildur, the father of Aragorn's ancestor, and was broken when Isildur used it to cut the One Ring from the hand of Sauron at the end of the Second Age. The sword's reforging symbolized Aragorn's role as the heir of Isildur and his rightful place as the King of Gondor.

Andúril is one of the most famous weapons in modern fantasy literature, and has been featured in many adaptations of the Lord of the Rings, including the Peter Jackson film trilogy and numerous video games.
