This puzzle box was bought about 25 years ago direct from Japan along with a similar 66 move box (see my other listing). I am not a puzzle collector, these are the only two boxes I have. I bought them as I have a long standing connection to Japan with many trips there through aikido.This box has been stored wrapped in cloth inside its protective presentation box and kept in a cupboard for all that time. I have only taken it out of the box a few times: when I bought it and recently to photograph ...

The "TV Puzzle" is a long-discontinued Pelikan release that was the subject of particular obsession on the Mechanical Puzzle Discord. I somehow got roped into making it; I'm still not sure how. Those guys are persuasive.TV Puzzle is an interesting hybrid packing and take-apart puzzle. My interpretation stayed true to Jakub's original design with a couple of changes - we fully lacquered and changed grain direction for all pieces to make the solution more difficult. The result is trickier than I e...

This run was precisely crafted from Ash and Wenge. The fit and function are exact. Production turned out very well and is represen...

BurrBon is an utterly unique Interlocking Burr Puzzle. What could be better than a six-piece burr? How about a six-piece burr inside another six-piece burr? There are several ways to build the inner and out burrs separately, but only one possible configuration assembles them together. The interaction between inner and outer pieces is what makes this an extraordinarily difficult puzzle.The construction of BurrBon required just the right balance of tolerances to allow the inner burr to move smooth...

Despite the devilish difficulty of this puzzle, let me assure you that Derek is a really nice guy. Keep that in mind as you go crazy trying to solve his latest creation. Derek's half dozen is fiendishly difficult at a level 26.9.5 solution. It's so hard to solve I took pity and made the pieces from three woods so you'd have a big clue as to what goes where. I'm also shipping it assembled. You're welcome.Construction is dead on with VERY nice tolerances. Everything's square and beveled, with thro...
