Set of four Constrained Burrs by Logan Kleinwaks, made by Eric Fuller. His comments on the original listing:- When Logan sent me the first puzzle in this series, the Bookend puzzle, I was very impressed. The concept was interesting, the solution tricky, and of course the finished puzzle displayed very nicely. He then followed it up with three more complimentary designs, each with a unique solution. I knew immediately I wanted to make them, and so now I'm very glad to be able to share with you...

A unique puzzle that separates into 4 pieces, each composed of "planks" that are 1 unit by 4 units in size, and where the pieces are attached at 90 degree angles. Made in four different woods by Jean-Claude Constantin, who lives in Germany and designs/manufactures many different puzzles using different materials (wood, metal, etc.). Puzzle has a modern sculptural look that displays well in any collection. There's some slight bending of certain planks, but no significant effect on the o...

The last one gave an idea of the concept; this one kicks it up several notches!This non-millable six piece burr is surrounded by a cage split into two mirrored halves. Not only must the solver figure out the burr itself, but they must also understand the burr within the constrains of the cage. That alone would be...

A couple customers emailed me, asking if I Would make it. Looked like a normal 4x4 cube to me so I was fairly non-committal. Then several more customers chimed in over the next couple weeks, and I gave it a more serious look. While indeed a simple 4x4 cube (no rotations even!), this design steps up the diffic...

Six pieces need to be packed into the box. IPP souvenir by Matti Linkola.

I made Exploda Burr six piece burrs as souvenirs for IPP13 in 1993 for Bill Cutler. Bill's design consists of 6 identical pieces that assemble via coordinate motion into a 6 piece burr with no spaces inside. Several pieces were left behind due to chipped edges from the cutting process. So this burr consists of left over pieces with cosmetic defects that do not affect the puzzles function. The photo included shows the defects, 2 of which are visible in the assembled puzzle.

Got all that? Very tricky assembly, this burr shares a looping piece set that is not at all intuitive to assemble.Crafted with various exotic hardwoods, the fit is a bit loose due to the unsupported nature of the framework design. That said, it definitely won't be falling apart in y...

Quoting Lee's description: "Looking like clusters of six rhombic dodecahedrons, these puzzles are members of the Diagonal Burr family. Assembly is moderately difficult due to the dexterity required to align the two halves of the puzzle just right in order to get all of the pointy tips properly overlapping each other. Disassembly (i.e. "busting" the cluster) can be quite tricky because of the awkward placement of six fingers required to begin pushing the two halves apart. The classic version of ...
