The Callaway RAZR XF irons are game-improvement irons design to maximize forgiveness. The multi material club head includes a forged 1025 carbon steel body with a cavity insert. The club is larger and perimeter weighted to maximize Moment of Inertia with a wide sole and top line that is thicker than traditional blade irons. These irons combine game-improvement technology with forged iron feel, so they are great for the purist mid- to high handicapper.
