ABSTRACT:
A building block with integral hand hold and a method for making same. As with standard prior art masonry blocks, the building block of the present invention includes a central transverse web which provides structural rigidity to the block and divides the interior space of the block into two substantially equal sized areas. However, the building block of the present invention includes a cut-out completely through the central transverse web which facilitates placement of a mason's fingers therein in order to grasp and lift the block. A preferred method for making the blocks includes the use of a mold which allows the transverse web to be formed with the rest of the block, with the central cut-out then being punched out of the transverse web prior to kiln drying the block.
