I believe this was one of Akio Kamei's first designs that was subsequently produced by Bits & Pieces. Other than a few surface scratches it is in good condition and works perfectly.

ARTISAN SERIEFrom Cubic Dissection web site:" Stumbling Blocks is a brilliant puzzle that I've been wanting to make for a while. When Pit mentioned that he had a more difficult version I jumped at the chance to make it. Packing the four pieces into the frame is the goal, and the way to get there is amazing. I can't tell much about this puzzle without giving things away, but I'll say that it has one of the best "Ah-ha!" moments I've seen for a while. The movement of the pieces is beautiful and th...

The Buffalo Nickel Puzzle is based on the Nine-and-a-half-Moves puzzle by M. Oskar van Deventer. It is composed of just three pieces that fit together in such a way to hide a secret compartment. Although the three pieces are flat and lie in a single plane, it takes a remarkable 9 1/2 moves to solve.Originally made by George Miller for IPP 20 in Los Angeles, I believe this was subsequently reproduced by Bits & Pieces and is what is offered here.It is basically a two dimensional three pi...

ResQ is a unique Sequential Discovery Puzzle based on Boucher's brilliant Visitor Q. We took the original design and modified it by adding additional goals, tools, and tricks. ResQ is the result of nearly three months of prototyping and features previously unseen concepts and hardware. The brilliance of Boucher's VQ design is in the depth of possible movements and states the puzzle can be in. Visitor Q is very much like a maze; you find configurations that won't allow you to progress and mus...

Description from CubicDissection:The ODD Puzzle is a wonderfully challenging packing problem. Three rather large pieces must somehow fit through a wholly inadequate seeming slot to fill the box. The solution is creative and satisfying! This puzzle was the grand prize winner at IPP28.Construction of this puzzle excellent, with very precise cuts. The splines reinforce the mitered corner ensuring a long lasting joint. Fit is perfect, as it must be for this type of puzzle.Shipping calculated at auct...

Wil Strijbos made several bolt puzzles, including this design.The goal is to remove the ring (see last picture, no spoiler).This design is called "low number bolt" even though it is #9 according to Haubrichs catalog of bolt and nut puzzles.During the solve, a part of the inside can be seen and is rusty, this is not visible in the assembled state and does not affect the solve.

Wil Strijbos made several bolt puzzles, including this design.The goal is to remove the ring (see last picture, no spoiler).This design is easily recognised because of the nipple in the end of the bolt.This is WS #8 according to Haubrichs catalog of bolt and nut puzzles.This copy has a few rusty patches, in the thread and on the pin that extends from the nut.This does not affect the puzzle fuctionality.
