An Elvish long-knife of Gondolin — a sword, at hobbit-scale — found by Bilbo in the trolls' hoard, glowing blue when orcs are near. Bilbo named it after skewering the great spiders of Mirkwood, and it was his companion through dragon-riddling and battle. Passed to Frodo at Rivendell along with the mithril-coat, it cut the webs of Shelob's lair, and in Sam's hand it wounded Shelob herself — a deed no warrior of old had matched. Sam bore it home, last heirloom of the Quest.
