Six identical pieces, 3 different woods. Not terribly difficult, but not as easy as you'd think. Made by Bernhard Schweitzer in Germany. Exchange puzzle at IPP.

Bill kindly gave me permission to make one for my private collection, which I now have to sell unfortunately, again with Bill's permission. The Binary Burr functions like the Chinese Rings. There are 6 'ring' pieces. Each added ring multiplies the number of moves to remove the first piece by approximately 2. The number of moves required to take out the first piece is 85. This design was awarded a First Prize at the 2003 IPP Puzzle Design Competition - From Bill's Website Frame mad...

This is a "give-away" puzzle from an injection-molding plastics company called Protomold. Each piece is made from a different kind of plastic, with the type of plastic labelled on the side of each piece (like PC/ABS for polycarbonate/acrylonitrile butadienge styrene blend, etc). Neat gimmick! You won't find these very often, anywhere (although it is only a couple of years old). Comes with a little bag and instructions from Protomold. Like new.

This copy of the excellent pieces of eight is one of a kind. I had a lot of different wood pieces left over from the run I made several years ago, but not enough for a solid patterend copy. So, I glued together about 10 different species randomly. Result is a puzzle full of color! <P> From the website: RELEASED: 7.24.2007 PRODUCED: 30 Copies DESIGNER: Stewart Coffin CRAFTSMAN: Eric Fuller MATERIAL: Cherry Box, Various Hardwoods ...

I bought this when it was released in 2007. I have played with it a little and kept it in perfect condition. It comes complete with the box, the chess pieces (and box/green bag), the instructions.As seen here, http://www.cubicdissection.com/html/purchase/discont/stickchessbox.html, this puzzle description:Each Stickman Checkmate (No. 13) Puzzlebox has been quality hand-crafted from the finest holly, mahogany and leopardwood and comes with its own set of hand-carved travel-sized chess pieces. ...

Gravity Well, Bits and Pieces puzzle #07-7390. Comes with instructions and original box. Center "gold" colored piece shows signs of some corrosion, or the plating is flaking off. Aluminum frame has a nick on one edge. Not a perfect copy of this puzzle.

I didn't know whether to call this a "take apart" or "put together", but since I've never had it apart, I guess it's a "take apart" puzzle. It looks like a soccer ball, and it has Russian letters on it; if you can read it, maybe you'll know what it says. I don't remember where I bought this; either IPP 2000, or from Japan. No box, no instructions, just a little plastic stand and the ball.

In the words of Bill Cutler: "Can you make a 6-piece burr which consists of 6 identical pieces, has no internal holes, and can come apart? I had found an answer to this question many years ago. The design mixes the construction of the 'Star Burr' with that of the 6-piece burr."

This is a one of a kind new design. I had a box left over from the recent run of Kim NoPack puzzles, and also some extra pieces left over from the Pack 6 puzzles. I was about to throw them in the scrap bin, but something clicked in my head. So, I plugged the pieces into Burrtools and found that it was actually a pretty interesting packing puzzle. There are two non-symmetrical solutions possible. The winner of this auction will receive a copy of the BurrTool solution file. Signed and dated...

Beautifully made puzzle box from cubicdissection.comEric's description:My latest puzzle box is a nice compliment to the previously released "Splined Box" series. The size and basic apearance is the same, but the function and operation is very different. This sliding panel design has a nasty twist that left many experienced puzzlers out in the rain for some time. I'll not say too much about it other then that the 15 copies I brought to IPP sold out immediately. buyer is responsible for all ...
