A Callaway iron is a type of club used in the game of golf to propel the ball towards the hole. Irons have shorter shafts and smaller clubheads than woods. The head is made of solid iron or steel, and the heads primary feature is a large, flat, angled face, usually scored with grooves.
Callaway Irons are largely used when you are less than 200 yards away from the green. The closer you are to the green, the higher the iron you will use. A standard set of Callaway irons consists of 3, 4, 5, 6, 7, 8, 9 irons and the pitching wedge (PW). Callaway Irons either belong to one of two clubhead categories: the cavity back or the muscle back. The muscle back irons features smaller head than their counterparts and are generally made using the forging process. Cavity back irons usually feature larger heads that are made by hollowing out of the back of the clubface.
