from Karakuri website:The “binary” is used by different way until now. This way may be more primitive usage. Unlock the drawers by moving the bars. To see the number of 3 and 8 did you get a hint? Each bar means each place of binary. When a bar is opened, it means 1, and a bar is closed, it means 0. Each drawer means 0, 1, 2, ….and 7. “Move up of digit” is expressed more exactly. Similar mechanism will be possible at trinary and others. But, more than at least 18 drawers must be made i...

From karakuri website:Three cubes are connected.It is impossible to separate them.One of joining plates is the key.If you slide the 1st step plate of one box, you can not open the other two boxes.It takes 38 (8+7+8+7+8) moves to open all the lids at the same time.This box is completely different from Snake Cube(KW-6).I developed completely new mechanism.

Kawashima's excellent Christmas Present from 2013...from his Karakuri listing:This work was designed as a Christmas present for 2013.The purpose of almost all karakuri boxes is to open a lid. However, the goal of this box is to take the ring off of the box. Although the mechanism is different, the purpose is the same as KW-17. ** I have not done any checking of movements other than accessories. It may be impossible to remove it according to the form of the ring.

Kawashima's excellent Christmas Present from 2014..from his Karakuri listing:The purpose is the same as Ring box(KW-17),Ring box 2(KW-20).I made this with every mischievousness, but mechanism is simple.

IPP17 six piece burr in a box. Overseas shipment $22.75. 

This work was designed as a Christmas present for 2009.This is part of the series of "Packing Box". The last work was a square shape but this work is a rectangular shape. It's easy to open, but watch out for the two 'dummies'. Are they the craftsman's joke??Includes original box. No answer card was included but a sheet was published later.

From Mr. Fuller's website:Here is another extremely difficult burr along the lines of the Binary and Ternary burrs, and Cutler's cube puzzle. Cubloc bridges the gap between those puzzle, being very difficult to solve and disassemble but without the predictability of the n-ary burrs. The six pieces interact with the cage to form various gates which interact in a complicated way. It is exceptionally difficult to disassemble, with many dead ends and wrong turns. This puzzle is no joke. Be forwarned...

Kinoko Box by Kyoko Hoshino, from Karakuri Group, 2016.

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.

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