How to Cut Flagstone

What You'll Need
Tape measure
Hammer and heavy duty chisel

A flagstone pavement or patio can add a handsome element your home. However, building and installing flagstone may seem intimidating. Fortunately, with some basic masonry skills and the right tools at your disposal, you can do the job yourself. Cutting the flagstone is by far the hardest part.

Step 1—Preparations

First, place the flagstone in a flat place where it is completely stable. To accomplish this, you may need to use sand or wooden blocks to keep it firmly in place. To prepare the stone for cutting, use the chisel and tape measure to etch lines into the stone where you want to cut it.

Step 2—Cutting the Flagstone

To cut the flagstone, go back over the lines that you have etched into the stone using a hammer and chisel to start spitting it. Be careful not to use too much force, as you can end up causing the stone to shatter. What you need to do is to gradually chip a line into the stone until it falls apart of its own. If you are using thicker stones, you may need to do this on both sides.
