This puzzle is comprised of six different notched brass bars that interlock in one specific way to create a unified "jack" shape.
It's exactingly milled by a skilled machinist in Rhode Island 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...
