Signed & dated 2007From Mr. Cutler's website:"I had always been interested in designing burr puzzles which are difficult to take apart. The burr shapes I had used to this point all had the same symmetry as the 6-piece burr or the 24-piece burr - mathematically there are 24 symmetries to these shapes. However, keeping all these symmetries and creating a new shape resulted in burrs with lots of Starting with the Wausau'81 burr, I experimented with shapes which had different 'patterns' of rods alo...

this ordinary looking board burr is anything but ordinary.not too difficult - at level 2.4.4.

Cubicdissection.com description: "The 3x3x3 cube is pretty played out. With only 27 units there are only so many things you can do with it. That's assuming tradition block glued to blocks...if you open up edge connections, a whole new world of complexity appears! Markku's excellent Liberal Cube makes good use of these dynamics, with a very confusing and difficult seven piece serial assembly. I would estimate that the difficulty is on par with Coffin's Convolution design which of course uses a 4x...

This beautiful puzzle hasn't gotten as much love and attention from me it deserves, so I'm offering it up for sale to someone more deserving, and clearing some space on my puzzle shelves for some future puzzle crushes ;-) Mekano consists out of 4 seperate pieces and a Frame. The aim of this wooden puzzle is to disassemble all pieces out of the frame and put it inside again. You can take apart the first piece after 23 moves. Level: 23.4.5.2

Cubicdissection.com description: "Amulet is a tricky and interesting variation on the standard six piece burr. To quote Allard's blog post about it: "He’s fiddled around with a standard six-piece burr and added a few constraining voxels around the middle and shorted one of the axes… adding those voxels makes all the difference it turns out – without them there’d be 144 solutions, with them the solution is unique… and quite tricky!" Construction of this puzzle is excellent, with a ni...

A very interesting twist on the traditional "pack the burr pieces in this box", Wedged captures one undersized burr piece right in the middle of the action.

This puzzle is a derivative of Karin Von Kanel's outline burr, designed in 2001. I have been wanting to make this for a long time, but was having trouble getting in touch with Karin. Finally I ran into her at the NYPP and she heartily agreed to give me permission to make it. Initially I wanted to make the "Ultimate" level 15.1, but when I plugged it into burrtools, no solution was to be found. I started playing around with the piece sets and decided on one which had three pairs of nicely symmetr...

Don't know the maker but works great.

Cubicdissection.com description: "The Binary Burr is a classic Bill Cutler design. It was awarded a First Prize at the 2003 IPP Puzzle Design Competition, and has been unavailable for several years. Here is what Bill has to say about it: "The Binary Burr is a burr that functions like a 6-ring version of the Chinese Rings. The puzzle consists of 21 pieces. One is equivalent to the ‘bar’ in a Chinese Rings puzzle, and six others are equivalent to the ‘rings’. The other 14 pieces in the p...

From Eric's original description :"I very much enjoy rectilinear puzzles with rotations...there's just something interesting about non-linear moves in puzzles which look like they should not be able to move that way. Bergmans "Sun" is nearly the platonic ideal of such a puzzle. No edges are rounded. There's very little structure to give hints. The solution has several dead ends, and even starting can be quite tricky. While this is not a puzzle that will take days to solve, it's def...
