This hefty interlocking Jack Puzzle from Craighill comprises 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 in Massachusetts 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…

(Hand-drawn assembly instructions are included) 

A sleek and modern take on the traditional six-piece burr puzzle.

Craighill Jack Puzzle measures about 7.6 x 7.6 x 7.6cm (assembled) and weighs approx. 500gms. 

Solid Cartridge Brass (alloy 260 – 70% copper, 30% zinc)

Bull-nose ends, lathe-cut
