Puzzle design by Vin&Co from Czech Republic., designer Vaclav Obsivac.
A strict definition of a half-cube is one part of the dissection of a cube into two identical parts. Both parts have the same shape and volume. The dissection may be a single cut along a orthogonal or a diagonal reflection plane or a more elaborate combination of cuts resulting even in half-cubes separating along one axis only. Puzzles made from half-cubes separating in many directions are in general assembly- or box-filling puzzles; but puzzles from half-cubes separating along one axis only are interlocking. We can broaden this definition by allowing cube dissections producing mirror images as half-cubes as well. Designing puzzles on the basis of half-cubes involves changing them so mutants are created that no longer have the volume of half the cube. The definition of a pair of “mutant half-cubes” is any dissection of a cube in two pieces. Here both shape and volume may be different, the only condition is that the two pieces combine into a cube. This definition allows many different pairs of mutant half-cubes.

Koncy Wooden Puzzle - Brain Teaser
$28.99
This dynamic cube is one of our hardest, and also happens to be one of our favorites. The Koncy Puzzle contains six pieces. Nothing connects these pieces to each other, or lets the cube retain its form, besides the unique and unconventional shapes of the pieces themselves. Dismantling this cube is a very complex and gentle affair. It should be done one step at a time, and is difficult in and of itself.
The 6 pieces slide apart and return to a cube. It is important to note the last piece to come apart as it is the last to be inserted as the cube is reassembled.
