Supernatural - Ruby Demon Killing Knife

The Demon-Killing Knife, or Ruby's Knife, is an ancient knife that was created by the Kurds which possesses the power to permanently kill demons, hellhounds, and other demonic entities, but not the Whore of Babylon as Castiel said that only cypress wood can kill her. Though it somehow came into the possession of Ruby, it eventually passes onto Sam and Dean Winchester, who use it as their most common means of killing demons.
