The Skewb was invented by Tony Durham. It is a puzzle that has four turning axles. It has little metal pieces in it to fix the sides into the right positions. The weight of a Skewb is normally about 150g. It is a deep vertex-cut cube; each cut divides the cube into two congruent pieces by a hexagonal plain which passes through all six faces at two adjacent edge centres.
It is said that the Pyraminx (ignoring the corners) and the Tetraminx are isomorphic with the Skewb; that is, a solution for either will work on the other. That is technically not true; the true cubic equivalent of a Pyraminx/Tetraminx is the Ivy Cube.
Higher order Skewbs, named Master Skewb and Elite Skewb, have also been made. They have more layers. Differently shaped puzzles with the same mechanism include the Skewb Diamond, Skewb Xtreme, Skewb Ultimate, and an unnamed puzzle in the shape of a rhombic dodecahedron.
World Records Edit
The single world record for the Skewb is 1.68 seconds, set by Jan Beltage, and the average is 2.99 seconds, set by Michael Rezwuzki.
