Sharp Roof House, by Hiroshi Iwahara, from Karakuri Group 2016. Easy puzzle.

Bad Radio. This is a large, heavy puzzle (nearly 4 pounds) by Akio Kamei; unfortunately, the right-hand knob is a little wobbly or loose. It's not supposed to do anything but rotate, so it is a minor defect in the otherwise perfect puzzle. The puzzle functions as it's supposed to, but you are NOT supposed to pull on the knobs to solve it. Originally listed to members at about $740, I'm starting the bid at $500.

Striking appearance with Bloodwood. #85 STC 1990 written inside of puzzle in pencil, see photo. Detailed instructions included.

Windmill. Designed by Iwahara. This is a very easy puzzle from the Karakuri Group, almost more box than puzzle.

String Box IV by Akio Kamei, with his stamp, Karakuri 2016 Christmas Gift, in original box.

Eric's Description: With the invention of the NOS (New Old School) puzzle series, Gregory took the six piece burr format and turned it on its head. The only thing more noteworthy than the uniqueness of the series was how difficult they are to make. When he sent me the plans for them a year ago, I turned him down because it just looked like a nightmare to manufacture. I wasn't wrong...BUT...Gregory came up to me at IPP this summer and let me play with a couple three D printed versions and I was h...

Eric's Description: I was browsing through AP-ART when my eye fell on Mr. Coffins design #187 family. I have not made a cool tray puzzle in a while, and this seemed like just the ticket. I also had a nice bunch of ebony and cocobolo that would be perfect for it!.About design #187, Stewart says:"The three puzzles in this category all have a 5×5 square two-sided tray. On the back side is a simple framed square for practice exercises. The front side has a Plexiglas cover with openings cut in it th...

Eric's Description: Another maze! This one is TRICKY. The goal is to move the ball bearing from one side to the exit. Once you drop down the rabbit hole you realize that the state of the maze changes by pushing the shuttle up and down. So not only must you figure out the internals, but you have to figure out the state the maze is in depending on shuttle location. A maddeningly difficult and interesting design...I think this may be my favorite of the update.Construction of this puzzle is super ni...

35 moves to remove the first of eight wenge pieces, it rattles just a little in the process but the fit is really very good.

RELEASED:2.28.2014PRODUCED:38 CopiesDESIGNER:Bill CutlerCRAFTSMAN:Eric FullerMATERIAL:Walnut, Ash, SapeleCOMMENTS:This is possibly the best burr puzzle ever invented. Bill designed it by hand when he was 16 years old. (so, a looooong time ago :)Intended as a take-apart puzzle, disassembly is very tricky with many many false starts and dead ends. Reassembly is of course very very difficult. I don't generally include instructions, but I will gladly send the directions to this one should the buyer ...
