An incredible creation by Katsuhiko Okamoto. A very rare puzzle for many years it became mass produced in 2011.
The first Master Skewb was built by Katsuhiko Okamoto in 2003. For almost seven years it was a very rare puzzle. Only the sample built by Katsuhiko existed. In december Andrew Cormier presented a master skewb made from his own design. Five months later Tony Fisher presented his version made from a face turning octahedron which became available at that time.
All these redesigns increased the communities wish to get this puzzle mass produced. This wish came true near Christmas 2010.
The puzzle itself is a cornerturning hexahedron like the namegiving skewb but has 2 cuts per axis compared with the one cut of the normal skewb. If the edges and X-Faces are ignored the puzzle solves identical to the skewb. It is closely related to the face turning octahedron and the rex cube which were invented a long time after this.
The mass produced version has and edge length of 57mm and weighs 134 grams.
