Take your golf game higher than you ever thought possible with the Callaway Apex Forged Irons. Break the mold, and dare to be different, with these extreme, high performance forged irons. The ultra hot face insert, crafted from thin 455 Carpenter steel, increases ball speeds an additional 1-2mph for additional distance and carry. Tungsten weighted sole inserts, found in the long irons, help lower the center of gravity which produces higher launching shots. Wide club face grooves deliver consistent spin, from all lies, for greater stopping power on the green.
