Fisher cube

From Speedsolving.com Wiki

A Fisher cube is a 3x3 cube, invented by Tony Fisher, that has been rotated on one axis rotated 45 degrees internally, known as fishering. Four of the sides have center orientation, as the centers on those sides are now in the place of edges. The edges on those four sides have no particular orientation. Many different twisty puzzles have been fishered, such as the 4x4 cube, the Skewb, and some cuboids.
