Craighill Jack Puzzle

The Optimist

Regular price $95.00

The Jack Puzzle is comprised of six different notched brass bars that interlock in one specific way to create a unified "jack" shape. It is exactingly milled by a skilled machinist, and weighs just over one pound. 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.
