Firmly strike the score with your chisel and hammer to break unit along your scored mark.
Method 2: Powered Saw

Using a concrete cut-off saw or platform masonry saw will give a clean, precise cut.
Using straight edge and chalk or pencil, mark trim line on concrete unit.
Start saw and line up marks with saw blade. Carefully ease unit into the cut.
Take your time and don't try to go too fast.
Make sure saw comes to a complete stop before moving cut unit.
Method 3: Splitter
(Not Mentioned in Video) Splitters are exceptionally easy to use and can be rented at any RCP Block & Brick location.
A splitter will give a fairly precise, but jagged cut.
Mark trim line on concrete unit.
Insert unit into the splitter, lining trim mark with top and bottom angled teeth/edges.
Tighten down the top jaw by spinning the two handles in a clockwise direction until concrete unit is firmly situated between the two.
Once secure, pull down on the splitting lever until concrete unit splits.
