In the 1920s, Walter Schlage created an artifact lock pick that can open any lock after he grew tired of locking himself out of his own inventions. It was used by Pete and Myka to unlock the Count of Saint Germain's Crypt in order to snag the Count of Saint Germain's Ring, and by Artie to unlock the Hobbes Gallery while looking to snag Vincent Van Gogh's Stormy Night. It's currently in Artie's Bag.
