The Men of Númenor, described as "of Westernesse", gave magical powers to named swords such as Narsil (reforged for Aragorn as Andúril), Orcrist, and Glamdring, as well as smaller unnamed knives like the one that Bilbo called Sting, making them shine blue when the enemy in the form of Orcs were nearby; these weapons terrified the enemy, who would not willingly handle them, and greatly feared them in battle. The Men of Númenor had similarly bound the knives that Tom Bombadil retrieved from the Barrow-wight with spells specifically designed to destroy the Nazgûl. It appears as a fortunate coincidence that Merry uses one of these weapons against the Lord of the Nazgûl in the Battle of the Pelennor Fields, breaking the spell that protected him from death, and enabling Eowyn to kill him.
