This is a "rap" puzzle; it has a magnet. The round peg in the square stick rotates. The round peg comes out if you solve it.  I don't know the actual name (but it's shaped like an F), but I think I might have bought it from Constantin about 20 years ago in Essen.

It may be a bit tight in very high humidity situations.

Eric's Description: Frank's designs can be few and far inbetween, but are generally worth waiting for. "Burr Bones" is no exception. This three piece devil is a crafty level 24 solution with TONS of dead ends and trickiness. The skeletonized traditional three piece shape looks stuning in contrasting woods, and the completed puzzle is surprisingly stable. Like many of Frank's designs, this was not an easy puzzle to make.
