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.

Concrete block splitting and pitching apparatus

A precast, crushed stone landscape edging module comprises block body, a first, bidirectional interlocking joint, and a second, bidirectional interlocking joint. The block body has a first outer surface and a second outer surface and a first end surface extending from the first surface to the second surface and a second end extending from the first surface to the second surface. A first bidirectional, interlocking first joint is disposed on the first end surface and a second bidirectional, interlocking joint is disposed on the second end surface, wherein the first bidirectional, interlocking joint adapted to interlock with the second bidirectional, interlocking joint to prevent slippage and to enable rotation of the block body. The first bidirectional, interlocking joint has a first sawtooth and a first recess positioned adjacent to and joining the first sawtooth. The first recess is designed to receive a second sawtooth with a shape and dimension comparable to the first sawtooth. The second bidirectional, interlocking has the second sawtooth and a second recess positioned adjacent to and joining the second sawtooth. The second recess is designed to receive a sawtooth with a shape and dimension comparable to the first sawtooth. The first bidirectional, interlocking joint also has a first flat surface extending from said first outer surface to a first sawtooth and a second flat surface extending from a second outer surface to a first recess. The second bidirectional, interlocking joint also has a third surface extending from the outer surface to the second recess and a fourth surface extending from the second outer surface to the second sawtooth.
