Please feel the subtle resistance of the spring, and combined movement of the drawer and the red plate.

My latest box is the only box design I have collaborated on since the Stickman #4 with Robert Yarger, nearly five years ago.

To my knowledge no other puzzle box uses the mechanism nor solving methodology that the Beaulid does.This box shares s...

From Mr. Cutler's website: "I had always been interested in designing burr puzzles which are difficult to take apart. The burr shapes I had used to this point all had the same symmetry as the 6-piece burr or the 24-piece burr - mathematically there are 24 symmetries to these shapes. However, keeping all these symmetries and creating a new shape resulted in burrs with lots of Starting with the Wausau'81 burr, I experimented with shapes which had different 'patterns' of rods along the 3 axes.
