Lufielne's knife was said to be able to cut through anything. In the Grimm diaries, the legend of the elf Lufielne and the girl Cordelia is retold on the page opposite the Waage. ("Pilot") Lufielne provided Cordelia with his knife to ease her work. Aulden, her jealous brother, stole the knife and cut off the elf's hand. Cordelia stole the knife back from him and returned it to the elf.
