Featured in a December 1991 article in Fine Woodworking Magazine. Described in Stewart Coffin's book The Puzzling World of Polyhedral Dissections; here is some of what he says in the directions that came with the puzzle:"Special version - only one made. No half-pieces, so ignore puzzle problems that require half-pieces. The cube has only one solution in which all sides have matched wood and grain symmetry."

Dated November 2006. Signed. Number 8 in the set. 

Geneva is the first new puzzle by William Hu in quite some time. Named after the clockwork mechanism that it's partially inspired by, the level 9.3.4 solution includes some very unique rotations and coordinate motions. During assembly, there's a fair amount of freedom, with a lot of dead ends to run into and circles to run around in. Geneva is a nice addition to any TIC collection.This puzzle is shipped disassembled.Precision wood puzzles can be damaged by environmental changes. Please read the...

Five is the magic number! This "Turning Interlocking Cube" has a level five solution, with five rotations and five different wood types. Designed by Andrew Crowell, these fascinating TIC's take it to the next level. Instead of straightforward linear moves, these designs require rotations during the solution process. Construction is outstanding, with shouldered joinery where side grain gluing is not possible, and detailed bevels which flow around the shouldered joints for a uniform appearance.Thi...

Irregular board burr by Yavuz Demirhan. I do not have a definite record of the wood species, but I believe they are Maple, Padauk, Wenge. Shipping is from California, USA. I will ship worldwide; buyer to pay actual shipping costs.

Oskar's Matchboxes has always been one of my favorite designs. In terms of originality, appearance and overall appeal, very few puzzles come close. The five dissimilar pieces consist of an outer box and inner tray cleverly glued together. The goal is to assemble the pieces so that every tray is contained inside a box. With only two solutions, this is quite tricky!Oskar’s Matchboxes is a very time-consuming puzzle to make, with all pieces constructed using the same shoulder joinery that we used...

Boron is a moderately difficult puzzle that displays like a piece of sculpture once it's solved. The 12 pieces are made with contrasting hardwoods and precision-crafted in our North Carolina workshop. Its interlocking nature means that several pieces have to shift around to release the first piece. This puzzle is a lot of fun and a great addition to anyone's collection, beginner or advanced. Boron is delivered disassembled.For multiple items, combined shipping is available. Simply message me on...

A small but good-quality set of 13 length-8 burr pieces. (From the photo it looks as though a piece is missing, but the set is complete; it is a 13 piece set that comes in a box that could hold 14.) Craftsmanship is solid but not top-tier. Excellent condition. Shipping is from California, USA. I will ship worldwide; buyer to pay actual shipping costs.

Another classic by Oskar van Deventer, the Paperclips puzzle is rarely made, and for good reason. The length of the sticks and small surface area for overlap at the edges makes it very difficult to construct. Each corner is reinforced by a shoulder joint, then sanded flush and further reinforced with a full length spline. This is a very time consuming process, but is the only way to ensure the strength and rigidity necessary for this work of art.The result is worth the effort. With two possible ...

A neat turning (rotational) interlocking cube by Lucie Pauwels. It feels slightly tight, but by design, not due to the condition of the item (it is identical in fit to when it arrived, and I am the original owner). The photo is of the actual item being sold. Description from Pelikan's website:This puzzle measures: 64 mm x 64 mm x 80 mmMaterial: American Walnut, Mahagony, Maple, Wenge and AcaciaLucie Pauwels wrote about it:“One day I was playing with 2 spirals that form a cube, I added a few b...

25 piece burr cube by Alfons Eyckmans (signed on inside of one piece).Level 24.10.1.1.1.2.2.5   This is a very challenging design - the cube will ultimately come completely apart into 25 separate pieces. Burrtools file available upon request. Note that it appears externally the same as Arne's Cube (also by Eyckmans) but is in fact a completely different (and somewhat more difficult) design internally.Puzzles are kept in a pet-free room of a smoke-free home, temperature consistent between 68 an...

Jack Krijnen composed and made this burr set and named it the Phoenix Family. The set allows for the assemblage of Supernova, Excelsior, Barones, Burrly Sane for Extreme Puzzlers and Tiros, as well as several unnamed high level standard 18-piece burrs. All these burrs share comparable solutions, and have in Phoenix, designed by Alfons Eyckmans in 2008, a starting point for further explorations by Alfons and Jack. Hence the name of the set. The numbering of the pieces is deliberately chosen in su...

PendanTIC by Andrew Crowell, made by Brian Menold from Wood Wonders.  1.1.2.26.6 with 10 rotations. Assembled currently, let me know if you’d like me to disassemble prior to shipping. Buyer to pay 3% PP fees based off winning bid. 

Selling all of my remaining burrs. From Cubicdissection:Secret Burr is a re-release of a puzzle I made very limited copies of in 2002. Unique in that it's difficult in both assembly and disassembly, there are two locks inside the burr that interact much like Cutler's Ball Bearing Burr. Instead of steel bearings, Secret Burr uses small wood rectangles. Precision crafted of fine hardwoods, this puzzle not only looks exotic, but has the trickiness to back up its appearance.68 copies made for sale,...

Taken from the Cubic Dissection website, Eric Fuller described Cup of Coffee as the "most unique six piece burr inside a frame that I have ever seen. The four milled sticks interact with two boards in a slotted frame designed to look like many people's favorite thing...a cup of coffee! With a unique level 21 solution, this is strong coffee indeed."Limited to 41 copies, each dated and signed for April 2016.

Description from puzzlewood website :"This new design is part of a serie of Turning Interlocking Cubes (TICs) which was started in 2013 with Matador and Turnkey; it hs 5 pieces which should be assembled into a cube with an interesting sequence of different moves including turns; that`s the reason you will not get any help by a computerprogram as f.e. burrtools by A. Roever""The solution level of 5.2.3 is not complete without some necessary turns"A wonderfull design from a wonderfull desi...
