this is a very nicely made puzzle by Hideaki Kawashima.not terribly difficult, but the movement is very tight.

this was Hiroshi Iwahara's Christmas present in 2014.It has two compartments and is quite tricky

interesting 'burr' shape.however the movement is incredibly tight, borderline unworkable... hence the unsolved pictures...

while not a difficult puzzle, it is incredibly made, as is expected by Kagen Sound (nee Schaefer).comes with instructions for replacing the paper inside the book, but not for opening the book.

The object is to remove the rod.

As soon as Eric saw this design he knew I had to make it. The eight pieces pack into the oddly shaped frame only one way and in one very specific order. A fair amount of jockying around is necessary to fit them all. With a unique level 2.3.9.7.5 solution, it's doable but not trivial. A very unique concept from a new designer.Constructed of choice ash for the frame and exotic wood for the pieces, the tolerances on this puzzle are excellent. Operation is very precise at normal humidity. Furthermor...

Markus designed this puzzle quite a while ago and Eric always liked the looks of it. Finally Eric emailed him asking if the design was free...and it was! One hitch though - there was more than one solution. Eric greatly prefers puzzles with a single solution, so he decided to enlist Tom Jolly to see if it could be modified into a single solution. Tom quickly determined that the original had at least 15 solutions. Both Tom and Markus subsequently went to work, both coming up with interesting vari...

He's a smooth talker with a complex personality, and that describes this box pretty well. I brought the apearance of the box full circle to the first one, with the slight difference th...

RELEASED:11.29.2012PRODUCED:37 CopiesDESIGNER:Junichi YananoseCRAFTSMAN:Eric FullerMATERIAL:Canarywood / BloodwoodCOMMENTS:It had been a while since I made a simple six piece burr, and I really like them. They were the first puzzles I made when I was hacking away on my kitchen table nearly ten years ago trying to get a feel for this woodworking thing. So I felt like making another one...problem is, there are so many to choose from. I looked around a bit then remembered the small run of puzzles I...

RELEASED:2.13.2013PRODUCED:40 CopiesDESIGNER:Derek BoschCRAFTSMAN:Eric FullerMATERIAL:Ash / Wenge / BubingaCOMMENTS:Despite the devilish difficulty of this puzzle, let me assure you that Derek is a really nice guy. Keep that in mind as you go crazy trying to solve his latest creation. Derek's half dozen is fiendishly difficult at a level 26.9.5 solution. It's so hard to solve I took pity and made the pieces from three woods so you'd have a big clue as to what goes where. I'm also shipping it ass...

RELEASED:9.18.2009PRODUCED:30ish CopiesDESIGNER:Bram CohenCRAFTSMAN:Eric FullerMATERIAL:Maple or Curly Maple or RosewoodCOMMENTS:Bram has come up with a devilishly difficult construct here. The first piece slides out with decptive ease....after that gimme, it's nine more moves before the next piece is released. A hollow interior means maximum movement, maximum confusion and minimal hints. Starting with all pieces disassembled gives very few inferences as to a solving strategy. Overall a difficul...

Six very simple pieces, two of them even in congruent pairs, comes together for unique level 2.14.12 assembly. Lots of fun to solve, and certainly more approachable than the level may seem...if you're more of a beginner, don't let this one scare you off, you can do it! Contrast...

I enjoyed solving it a lot, and decided to make a run of them. To solve the puzzle, all the pieces must be put in the box. Easy enough, except for two things. One, they must all go thorugh the 1x2 slot in the side, making the order of insertion quite important. Tw...
