Up for bid is a 3rd edition (ca. 2015) of the Stickman #13 Chopstick Box in walnut and pecan.
Below is an excerpt from the Stickman website that provides additional detail about this amazing puzzlebox...
The design for the Stickman No. 13 originated as a concept for a magnetic lock, but Robert like the mechanism so much that it eventually became a small toy he would play with in his shop. This toy would catapult a single spear using repelling magnetism, then by switching polarities, would lock, load, and launch a second spear as well. The spears never went very far, but this unique mechanism eventually evolved into the chopstick puzzlebox.
Break one of these puzzles apart and its magnets can be seen, but few would have any concept of how it worked. It requires the interaction of four perfectly positioned magnets all working in tandem. Partially solving it allows one stick to pop out, but its removal changes the overall flux of remaining magnetic components, forcing the remaining stick to move to the other side, awaiting the last portion of the solution to pop out as well.
