To use this pretty gadget designed by Ralf Krämer in 2000, just slip the point into the walnut shell seam and turn it like a key -- and presto, your walnut shell will be perfectly split in two, each half intact for decorating baked goods or other uses.
It also comes on a long leather band and can be worn as a necklace when not in use!
