Jack Puzzle
This great looking 3D puzzle looks a lot easier than it actually is. The Jack Puzzle by Craighill is compromised of six notched brass bars that interlock in one and only specific way, but be forewarned, if you take it apart, you might not be able to figure out how to put it back together. Rest assured though, assembly instructions are included just in case. Precision milled by a skilled machinist in Massachusetts, the elegant piece is a desk object, a paperweight, and a true distraction.
