A hammer and chisel is best to cut or shape flagstone for small projects that do not require accurate cuts, such as a small garden path or a decorative step or bench top.
The measurement must allow for the space made by joint or mortar.
Allow time for this process, or you may crack or break the stone unintentionally.
The intent is not to saw through the flagstone; rather, the purpose is to create a significant score in the stone along which repeated blows with a hammer and chisel will break the stone.
Water is fed onto blade so it lubricates the cut and reduces the debris generated by the cut. [7] X Research source
