"So passed the sword of the Barrow Downs, work of the Westernesse. But glad would he have been to know its fate who wrought it so long ago in the North Kingdom when the Dunedain were young, and chief among their foes was the dread realm of Angmar and its sorcerer king. No other blade, not though mightier hands had weilded it, would have dealt that foe a wound so bitter, cleaving the undead flesh, breaking the spell that knit his unseen sinews to his will."
JRR Tolkien - The Return Of the King
