The Skewb (originally named the Pyraminx Cube) is a twistable puzzle in the shape of a cube that is cut diagonally 2 times along each of 4 axes. It is a cubeshaped puzzle. It consists of 6 center pieces and 8 corner pieces (four of which are attached to the central core). Unlike the Rubik's cube, which turns around faces, the Skewb turns around axes that go through its corners. It is a deepcut puzzle  ie. each cut goes through the absolute center of the puzzle, and exactly half of the puzzle changes with each turn.
This puzzle was originally called the Pyraminx Cube by Uwe Meffert, but Douglas Hofstadter suggested the name "Skewb", and it has been called that ever since.
