The Callaway RAZR X Forged irons are forged from 1020 carbon steel and are designed with the more accomplished golfer in mind. They feature a thin top line, narrow sole, short blade length, and a sharper leading edge, resulting in precision shot-shaping capability. They also feature Tour CC grooves that are spaced tightly together, resulting in 30-percent more grooves and improved control and workability. The forged head results in a soft feel and responsive feedback at impact.
