The Craighill Jack Puzzle might be harder to reassemble than take apart — a perfect desktop distraction.
Taking the Craighill Jack Puzzle apart might be the easy part. Made from six interlocking, precision-milled stainless steel bars, the puzzle goes together in one way to make a jack shape. It's the perfect distraction from the work you don't do anyway — or it might be better to just use it as a paperweight.
