Jack Puzzle by Craighill
The Jack Puzzle is composed of six different notched brass bars that interlock in one specific way to create a unified "jack" shape.
It is exactingly milled, and weighs just over one pound. A desk object, a paperweight, and 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…
