This three-piece puzzle looks like a set of antique skeleton keys that have been locked together. Your challenge, of course, is to unlock the pieces and take the whole assembly apart. Finding the solution to this puzzle is enjoyable but extremely difficult. If you manage to accomplish the formidable task of separating the pieces, you may be interested to know that there are at least three different ways of putting them back together.
