Sting was an Elven short sword made in Gondolin during the Goblin Wars. Bilbo Baggins found this short sword in a troll cave along with Glamdring and Orcrist during The Hobbit. Gollum was terribly frightened of anything made by the elves. This factor helped Bilbo Baggins with his encounter with Gollum on his way through the Misty Mountains.
