Customizing, Cutting and Modifying Blocks
Video: How to Build Split and Cut Blocks
How-To Sheet #210
The AB Courtyard Collection blocks come with a built in angle. By splitting the blocks at a quarter(1/4),half (1/2) or three-quarter(3/4) length, you create a straight side to the block. See the AB Courtyard product page for detailed information as to where the blocks are to be cut or split to fit properly.
The straight side that is created with splitting is needed when meeting up with a flat surface or when building curves within a wall panel. You can modify the blocks using a hammer and chisel when splitting or a saw with a masonry blade when cutting the block. Some of the blocks are produced with pre-marked splitting notches for ease of locating the cut line, but any ofthe blocks can be modified
Always wear safety glasses when splitting or cutting block. A dust mask is recommended when cutting block.

Cutting an AB Courtyard Block
Use a circular saw to score around the entire block in the same location where the split is needed to create a score line for the quarter(1/4), half(1/2) or three-quarter(3/4) length piece.Then with a hammer and chisel,tap around the score line until the block splits. A masonry saw or a metal chop saw can also be used to make a complete cut through the block, eliminating the use of the hammer and chisel.

Use a circular saw with a masonry blade to score around the entire block and then with a hammer and chisel score around the block until it breaks. This should yield a nice split.
Use a masonry saw with a dry cutting diamond blade. This method makes a complete cut and eliminates the need for a hammer and chisel.
