Cut Stones as Needed
If a stone has a sharp edge that could be a hazard to bare feet, knock the edge off with the back of a hammer and smooth it out by hitting with the front of the hammer. To reduce larger pieces, score the stone along the desired cut line. Line up a chisel on the score mark and tap with a hammer. Move the chisel about half a chisel-length down the scored mark and tap again. Repeat the process, working down the scored mark until the piece breaks off. Even up and smooth out the broken edges with a hammer. Always wear safety glasses when cutting or breaking stone.
