The Jack Puzzle is composed of six different notched brass bars that interlock in one specific way to create a unified "jack" shape. Precisely milled, and weighing just over one pound, it can serve as a desk object, a paperweight, or a true distraction — but be warned, if you take it apart, you might not be able to figure out how to put it back together.
