Draw a line on the paver along the path of where you want to cut it.
Clamp the paver down to a table or workbench to prevent movement. You do not want to hold on to the paver while cutting it.
Load a 4 1/2-inch masonry blade into your angle grinder. The blade is diamond-tipped to facilitate quick, clean cutting through the paver. Refer to your grinder's manual for proper installation of the blade.
Plug the angle grinder in, put on your safety glasses and align the cutting edge of the blade with the marked line.
Press the trigger to engage the blade of the angle grinder and allow the blade to cut into the paver. Do not push excessively; let the blade do the work. Gentle pressure is all that is required.
Let go of the trigger once the paver has been cut all the way through on the line.
