The Jack puzzle is comprised of six different notched brass bars that interlock in one specific way to create a unified "jack" shape. It's exactly milled by a skilled machinist in Massachusetts, and it weighs one pound. It's 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...
