Bricks are used in landscape design elements including borders, paths, walls, small patios, fire pits and outdoor fireplaces. Often a design plan dictates that some bricks must be cut to a certain size before they are placed. Have a few simple hand tools on hand so that individual bricks can be cut or shaped for immediate use.
Draw the cut line on the brick using a Sharpie pen so that the lines are easy to see.
Place your brick on soft ground or a sandy area so that the hammer blows you use on the brick are somewhat cushioned.
Wear safety glasses to protect your eyes from flying brick shards. This is absolutely essential for safety.
Place your cold chisel along the line, tilted at 60 degrees. Tap the chisel. You are not trying to break the brick at this point; rather, you are trying to cut a 1/16-inch groove along the cut line. Tip the cold chisel from side to side and once you have cut the groove, continue along the line until the entire brick has been grooved.
Place the brick set in the grooved line. The brick set is like a large chisel with one side beveled and one side flat. Place the beveled side toward the waste side of your brick. The waste side is the portion of brick you do not want to use.
Tip the brick set 10 degrees away from the waste side and hit the brick set firmly with your hammer. The brick should break evenly along the grooved line. You may need to clean up the edge with a few taps on the chisel.
