At first glance, looking at the picture, this may seem easy but in fact this puzzle by Ken Walker of Rivermore, California doesn’t seem un-lockable once you have it in your hand.
The five pieces, however, can most certainly be taken apart.
Putting them back together, however, is a whole new problem in itself.
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.”
