In Grimm 8, Bolte u. Polívka 1: 69–70, a little girl is forced by her
brothers to go out and cut peat with a dull knife. Her elf-lover
stretches out a sharp knife to her from the hill where he lives and
tells her to call him by striking on the stone. The brothers wonder how
she can cut the peat, and spy upon her. They strike the stone, take the
knife and cut off the elf’s hand, who thereafter disappears.
