Abstract
An apparatus for pitching and splitting a masonry block is provided. The apparatus includes a first pitching blade configured to move in a first direction. A second pitching blade is disposed adjacent to the first pitching blade, and the two pitching blades are separated by a distance that is small enough so that the splits initiated by each blade join into a single plane, thereby pitching and splitting the masonry block without the need for a splitting blade.
