At first glance, this puzzle by Kennet Walker of Rivermore, California seems unlockable. The five pieces, however, can most certainly be taken apart. Putting them back together, however, is a whole new problem in itself. A suggestion for solving this puzzle would be to not apply too much pressure. Solve it or not, the five pieces exude a kind of elegance, spiraling into a comfortable fit in the palm of your hand. The key word is 'spiral'.
