Description
The Jack Puzzle by Craighill 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…
The Jack Puzzle is one of the challenging 3D puzzles from Craighill's collection vers. Patience games. If you enjoy it, Tycho, Tetra, and Venn are other challenges for you.
