ABSTRACT:
A masonry block cutter includes four blades. The blades are arranged in two pairs with each V-shaped pair being secured together. When cutting a block having a square cross section, the cutter has a generally square configuration, with the opposed pairs of blades being pivoted at one corner of the square and having spaced-apart elongated handles extending parallel to each other and at an angle of about 45.degree. to the adjacent sides, at the opposite corner of the square. Hammer blocks are provided at the intermediate corners of the cutter, so that, when the blades are resiliently held against the block by the grip of one hand at the end of the handles, the mason may strike one of the hammer blocks and cleanly cut the masonry block at the desired point along its length.
