Up for Auction is Dan Lock. If you haven’t experienced this yet, why not? An absolute must have originally designed by Dan Feldman.The objective? It is your job to open the lock, and then to get it back to its original state. It comes with two keys: one key is attached to the shackle and the other one is broken.....Most padlocks, once opened, are easy to close: not so the DanLock. In fact, it is rather more difficult to get the lock back to the same state as it is delivered to you. Altogether ...

A reproduced Combination Lock of the 18th centurey

Looks like a standard sliding puzzle but it is not. The puzzle is ideal for sliding beginners (40 moves) but also very interesting for experienced sliding puzzlers

A very easy sliding puzzle

A nice Sliding puzzle. To solve you have to understand the trick.

Looks like the Fifteen, puzzle at first, until you notice that pieces, except for piece 15, are joined together in pairs. Described on page 151 of Hordern's book, who notes that are a number of ways to solve it. The designer has made the pieces sufficiently tight so that solution is possible Further Reading Dustin Patent,, from: www.uspto.gov - patent no. 1,993,211

A wooden 15 puzzle. This has been heavily abused and gouged by some idiot with a pencil, wood-burned, and partly sanded. Worst condition of any puzzle I've ever seen. On the other hand, it's also a fairly unique "15" puzzle with Japanese marquetry. And it's all there. You can have this poor, beat-up puzzle for a buck, if you need to temporarily fill a hole in your collection. I'm not sure where I got this from. This will be mailed in a bubble-mailer, with packaging that's 2 oz. I will not ship o...

The Binary Burr is a classic Bill Cutler design. It was awarded a First Prize at the 2003 IPP Puzzle Design Competition.Eric's comments at time of production:- "Construction of this puzzle was tricky. The humidity in my workshop was fluctuating wildly, so I opened up the tolerances more than I usually do to make sure the final product wouldn't bind up or get stuck. The good news is that I was successful there - this puzzle should work in all humidity conditions. The bad news is that the ...
