Abstract
A multipurpose brick-layer's tool is adaptable for use as brick tongs or as a mortar hoe. In one embodiment of the invention, the tool also functions as a band-cutter for cutting metal bands used in the packaging and transport of bricks. The tool is adjusted using a slide and guide arrangement. A pin and hole adjustment mechanism varies the distance between locking jaws of the multipurpose tool. In this manner, a specific number of bricks can be carried or a hoe handle of preselected length can be formed. An elongated embowed handle arches over the guide tube and has at one end thereof a first clamping jaw. The jaw end portion of the handle is rotatably affixed to a pivot pin extending through opposing walls of the guide tube. A slide tube carried within the guide tube extends outside the guide tube and carries a second clamping jaw complementary to and larger in size than the first clamping jaw. The second clamping jaw is a blade of a size and structure suitable both as a mortar hoe blade and a clamping jaw.
