In The Hobbit, Thorin and Company found Sting in a Troll-hoard along with the other Elvish blades Glamdring and Orcrist. Although it was just a dagger by the standard of Men or Elves, it made an excellent sword for a Hobbit. Bilbo Baggins used the weapon for the remainder of the quest. Gollum, who disliked anything made by Elves, was afraid of Sting. This fear helped Bilbo when confronting Gollum under the mountain in The Hobbit. Later, Bilbo gave it the name Sting, after killing a Giant Spider in Mirkwood.
In The Lord of the Rings, Bilbo gave Sting to his nephew, Frodo Baggins, just before the Fellowship of the Ring set off from Rivendell. Fear of Sting helped Frodo to tame Gollum (temporarily). It also helped Frodo and Samwise Gamgee escape from Shelob's lair, and Sam used it to seriously wound Shelob in combat. After the defeat of Sauron at the end of the Third Age, it remained with Sam.
Sting had the (apparently) magic ability to detect the presence of Orcs in its vicinity. When Orcs were nearby, it glowed blue, as it did when the Fellowship encountered Orcs in the mines of Moria. Sting also glowed in the presence of the giant spider descendants of Ungoliant, such as the spiders of Mirkwood in The Hobbit and Shelob in The Two Towers.
Sting also performed better than ordinary weapons in combat and against odd materials; it cut through the webs of giant spiders easily, whereas the blade that Sam brought from the Barrow Downs failed to cut through Shelob's webs.
