Each end makes a difference size joint for versatility. One end makes a 3/8" joint, then flip it around for a 1/2" 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.
