The bricklayer’s hammer, also called a mason’s hammer or
simply brick hammer, has a square face and a chisel-like cutting edge (Fig.
14-27). Like claw hammers, bricklayer’s hammers are also available with wood,
steel, or fiberglass handles and in different weights. The flat face of the
hammer is used for occasional nailing and for striking cold chisels. The other
end of the hammerhead can be used to cut bricks and concrete blocks. The brick
or block is scored on all four sides by striking with the cutting edge, and
then it is broken with a final blow on the score line.
