Due to its size and shape this is a great tool for tucking mortar into the joints as backfill or restoration. Each end makes a different size joint for versatility. One end makes a 1/2″ joint, then flip it around for a 5/8″ joint. Made from formed high quality steel for durability. The jointer is then sent through a unique heat-tempering process for hardness and long wear. The steel is then polished for a smooth, perfect joint every time. The shape of the tool provides knuckle clearance as you move along the joints. The overall length of the tool is 10 ½”” long. Proudly made in the USA.
