The Jack Puzzle is comprised of six different notched brass bars, exactingly milled by a skilled machinist, that interlock in one specific way to create a unified "jack" shape. A desk object, a paperweight, and a true distraction—but be forewarned, if you take it apart, you might not be able to figure out how to put it back together.
