Narsil (Andúril)Narsil - The sword that signified the king of Men in Middle Earth.  It was forged in the First Age by the Dwarf smith, Telchar, but its role in history does not come into play until the end of the Second Age.  There at the Siege of Barad-dûr, Narsil, wielded by Isildur cut the Ring of Power from Sauron's hand, though it was broken in two.  It was reforged and renamed Andúril in the Third Age when it was wielded by Aragorn, Isildur's heir.


"But Sauron also was thrown down, and with the hilt-shard of Narsil Isildur cut the Ruling Ring from the hand of Sauron and took it for his own." ~The Silmarillion (Of the Rings of Power and the Third Age)


"Slowly Aragorn unbuckled his belt and himself set his sword upright against the wall.  'Here I set it,' he said; 'but I command you not to touch it, nor permit any other to lay hand on it.  In this elvish sheath dwells the Blade that was Broken and has been made again.  Telchar first wrought it in the deeps of time.'" ~The Two Towers, chap. 6 (The King of the Golden Hall)
