Jack Puzzle Steel

The Jack Puzzle consists of six different notched steel bars that interlock in one specific way to create a unified "jack" shape. It is milled by a skilled machinist, and weighs almost half kilogram. 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…(Hand-drawn assembly instructions are included).
