This hefty interlocking puzzle from Craighill is comprised of six notched bars that combine to create a "jack" shape. Each piece is exactly milled from brass by a skilled machinist in Rhode Island and the assembled puzzle weighs in at almost a pound. A sleek and modern take on the traditional six-piece burr puzzle.
Precision design meets craftsmanship in these mechanical puzzles from Caighill.
