Can you take it apart... and assemble it again?
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.
My 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.”
