Bilbo's Sting (The Hobbit) Feat. Vsauce2 (1x25)

:

Certainly the tiniest of the three legendary swords, Sting was crafted as a dagger alongside Orcrist and Glamdring. Just as its siblings, it glows blue in the presence of orc and goblin. Lost in the Fall of Gondolin, Sting was missing for millennia. Finally, it was found in the cave of three trolls and taken by Bilbo Baggins.
