An Elven knife of the First Age, found by Bilbo Baggins in a troll-hoard along with Glamdring and Orcrist. Though only a small blade by Elven standards, it serves as a sword for a Hobbit. Like all Elven blades of that era, it glows blue when Orcs are near. Bilbo names it Sting after using it to fight the great spiders of Mirkwood, and he later passes it to Frodo, who carries it throughout the Quest of the Ring.
