Skewb

The Skewb in solved state
The four turning planes of the Skewb bisect it as shown in this figure.

The Skewb (/ˈskjuːb/) is a combination puzzle and a mechanical puzzle similar to the Rubik's Cube. It was invented by Tony Durham and marketed by Uwe Mèffert.[1] Although it is cubical, it differs from the typical cubes' construction; its axes of rotation pass through the corners of the cube, rather than the centers of the faces. There are four axes, one for each space diagonal of the cube. As a result, it is a deep-cut puzzle in which each twist affects all six faces.

Mèffert's original name for this puzzle was the Pyraminx Cube, to emphasize that it was part of a series including his first tetrahedral puzzle, the Pyraminx. The name Skewb was coined by Douglas Hofstadter in his Metamagical Themas column. Mèffert liked the new name enough to apply it to the Pyraminx Cube, and he also named some of his other puzzles after it, such as the Skewb Diamond.[2]

In December 2013, the Skewb was recognized as an official World Cube Association competition event.[3]
