Anglachel

In The Silmarillion by J. R. R. Tolkien, Anglachel (meaning Iron of the Flaming Star in Sindarin) is a sword smithed by Eöl the Dark Elf. Eöl gave this sword to Beleg as payment for staying in his forest, Nan Elmoth, though he did not relish giving it away. Beleg's wife, Melian, prophesied the following:

"There is malice in this sword. The dark heart of the smith still dwells in it. It will not love the hand it serves, neither will it abide with you long."

Whenever Beleg took the sword out of its sheath, the sword sang with gladness.

At one time, Beleg was unbinding the unconscious Túrin, who had been held captive. However, whilst undoing his bonds, the sword slipped or fell and cut Túrin in his foot. Túrin then woke, and not knowing who it was, slew Beleg with Anglachel, a mistake that he mourned for a long time.

Túrin was then given the sword by Gwindor, and Túrin travelled to Nargothrond, Gwindor's place of birth.

Anglachel was then re-forged by the expert smithies at Anglachel, and was re-named by its new keeper, Túrin, to Gurthang, which means Iron of Death.
