One of my fav burrs ever. Eric said this about the ones he produced (this one is made by Alfons).With a unique level 20.3.1.4 solution it's not for the faint of heart. Solvers are reqarded by a pleasing geometric sculpture that validates your puzzle credentials big time!

Stewart Coffin design Fancy This! #115-A made from mahogany.Seven pieces form the classic cluster shape, but instead assemble with both coordination motion and serial interlocking. IPP17 Exchange puzzle from Nick Baxter. Includes original box. The puzzle is in excellent condition, pieces go together tight and smoothly, a few small gaps in places once solved but displays very nicely.

From Pluedro:"Despite its decent and honest appearance, this puzzle requires 25 moves to remove the first piece from the assembled shape.While Juno had been playing with the idea of Grooved 6 Board Burr #1, he thought that there could be several variant grooved board burr puzzles dependent on where he put pins and grooves on the puzzle pieces. It was the reason why he put #1 to the first grooved 6 board burr. We might produce #3, #4 and so on if he finds an interesting idea for the series.Unlik...

Alastor by Terry SmartLevel 16.11.8.5.3.3.5 (very challenging!)In a mix of beautiful exotic woods - Sapele and Padauk sticks with Figured Maple frameCheck out PuzzleMad's Review: 

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."https://www.puzzlemad.co.uk/2020/01/theres-right-way-and-w...

Crystal Lattice 1, designed by Osanori Yamamoto, made by Pelikan. Comes with assembly instructions from Pelikan. Shipping weight with packaging is 8 ounces.

Icosahedron/Dodecahedron - design and made by Wayne Daniel. The fit isn't as accurate as it was when new; some small gaps opening up between pieces (see photo). This comes with a DVD called "One Hundred Seventy-Eight Cuts And Some Glue". I just now tried it in my DVD player; it works great.Shipping weight with packaging is 12 ounces. 

Chiasma - design by Yavuz Demirhan, made by Pelikan. Shipping weight with packaging is 12 ounces. 

Galaxy Z, designed by Osanori Yamamoto, made by Pelikan. Shipping weight 1 lb 1 oz with packaging.

Combination Lock STC128, Stewart Coffin - made by Mark McCallum, purchased 2009.This is a very tricky coordinate motion puzzle; finding the right way to get it apart is not easy. Six pieces. It took me about 1/2 hour just to find out how the thing came apart. The movement is smooth, but it's difficult to figure out the best place to push or pull. Shipping weight 12 oz with packaging.

Altekruse Surprise - Jerry McFarland. A couple of the pieces have tiny chips on the ends; you can see them in the photos. There also appears to be some slight shrinkage of some piece lengths with age (which you can also see in the picture, but it has no effect on the piece movement; I partly disassembled it with no problems. A lovely puzzle from 2008. McFarland's assembly instructions and notes are included.Shiipping weight 1 lb 3 oz with packaging.

Not a TIC, but TIC like!Brian Menold aka Wood Wonders made this gorgeous cluster puzzle from Andrew Crowells creation.  Puzzle is disassembled ready for your attempts to solve.  Brian says this about the puzzle:Notice this design from Andrew Crowell does not contain the typical "TIC" within the name! That's because this design is not a cube. Well, don't worry, there are still plenty of rotations. This star design is still a great design from Andrew. With 6 rotations and 18 total moves, I think...

This puzzle is a groundbreaking and highly anticipated design. Only 30 copies have ever been made in the past, and Brian at Mr. Puzzle sold them out very quicky. The Ternary burr consists of 22 pieces, with over 90 notches and and grooves. The unique solution requires 75 moves to get the first piece out, and over 90 moves to completely disassemble the puzzle. A very difficult work of art!Here is what the designer, Pit, has to say about it:"One evening, I was playing with Bill Cutler’s Binary B...

Berro Skull is a difficult 26 piece sequential assembly puzzle whose final form is a grim visage! The precision laser cut acrylic pieces must be analyzed and assembled in a very distinct order to realize the final form. While not as difficult as the upcoming 60 piece skull, it's nonetheless quite tricky and is recommended as a warm up to the more difficult puzzle (to be released in the fall).This is a prototype copy, and is smaller in dimension than the production copies. This puzzle is shipped...

Jerry's Cranium puzzle was too tempting for me not to make. An absolutely original idea, this solid acrylic puzzle is comprised of dozens of individual pieces which serially interlock to create a menacing skull that looks like something out of an adventure film! 88 moves total required for assembly. This was a very small run of puzzles so if you're at all interested in this, better grab it quick!This puzzle is shipped assembled.For multiple items, combined shipping is available. Simply message m...

I originally had this burr listed as the "Unnamed 13 Piece Burr". Thanks to Jim Gooch for pointing out that it is actually the "Secret Burr", which was designed about 15 years ago by Marcel Gillen. I have contacted Marcel and he graciously gave permission for this batch!There are two locks inside the burr that interact to make even disassembly a tricky proposition. Essentially it is the 13 piece precursor to Bill Cutler's Ball Bearing Burr, using small rectangles instead of steel bearings. Preci...

Reminiscent of Padaung Rings, this nifty little pocket puzzle is a lot of fun to solve. With a level 14.4.2 it's tricky but not impossible...once you get the correct alignment and piece selection, it flows fairly quickly.Coming in at a diminuative 2.25" on the long axis, Zauberflote will nonetheless grab your attention on the puzzle shelf thanks to the acrylic catching the light. A fun puzzle, one I'm glad I made.This puzzle is shipped assembled.For multiple items, combined shipping is available...
