How to make a split face stone?
Split-face is the most difficult surface to achieve, so practice your technique first on a scrap piece of stone. Set your stone on a sturdy bench so the face is vertical, as it will sit in the wall. Take the flat-blade chisel and hold it on the top edge of the stone at a right angle, then strike hard with a hammer to snap off a piece of material. Repeat all along the top of the stone. You’ll notice that some pieces will snap off farther down the surface of the stone. This is a function of both the angle of the chisel and how far you’re holding it back from the face. The more vertical the chisel, the deeper the shard will be. After you’ve cut the entire top edge, turn the stone and work your way around the whole outer surface, giving a rough split-face texture to the entire face of the stone.
