Challenge your mind with the precision-crafted mechanical puzzle that started it all.
  • Six interlocking Brass or Stainless Steel bars
  • 3" x 3” x 3” with lathe-cut, bull-nose ends
  • Doubles as a paperweight and playful desk distraction
Six different notched brass bars 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…

  • Available in solid brass or stainless steel
  • 1/2" diameter pieces
  • Bull-nose ends, lathe-cut
  • 3" x 3" x 3"
  • 1.1 lbs
