This burr-like puzzle was discovered by the Dutch computer pioneer Willem van der Poel during a lecture tour in Glasgow Scotland, while visiting the great Scottish mathematician and puzzle enthusiast Thomas O'Bierne.  Willem decided to use this design as his exchange puzzle at IPP21 held in Tokyo in 2001, as a tribute to O'Beirne.  This puzzle is unusual among burr puzzles in that it involves eight pieces, not six, and it has no holes, making it rather tricky to assemble.The puzzle is as recei...

Surface was the the IPP19 (1999, London) exchange puzzle of the prolific German puzzle designer and manufacturer Jean-Claude Constantin.  While Surface is still available as a new puzzle, this from IPP19 is the original version which is slightly larger than the current version, 141 x 141 x 20 mm as opposed to 133 x 133 x 18 mm, and made of metal and wood as opposed to all wood.  The object is to assemble the several pieces (8 pieces that are arrangements of sticks and cubes) into a 5 x 5 squar...

Letter Box is a very tricky packing puzzle. The 1x2 unit opening restricts the nine identical pieces which fill the 3x3x3 box. With multiple rotations and more than 50 steps, discovering the solution will keep you occupied for some time. This is an excellent design well-suited for the solver seeking a true challenge. We constructed Letter Box from some of our finest wood stock. The solid walnut box shows excellent striping and deep color. Each of the nine pieces was milled from solid stock ou...

One of the famous Sandfield Brothers' dovetail designs, this one by Robert, crafted exquisitely in two beautifully contrasting woods by the master Perry McDaniel.  Robert used this puzzle in the puzzle exchange at IPP19 (London, 1999).  The dovetail design provides the appearance that it was impossible to join the two pieces together, and that it is impossible to take them apart (which is the objective).  This is unusual in the Sandfield/McDaniel collaborations in that a good deal of dexterit...
