Add to those innovations extreme Notch Weighting, deeper 360 Degree Undercut Channel, and a constant-width sole and you have a game-improvement iron that explodes with technology. Extreme Notch Weighting: A proprietary design that redistributes more weight to the extreme perimeter of the iron to create a higher "Moment of Inertia" for greater forgiveness, more stability, and reduced distance loss of off-center hits. Deeper 360 Degree Undercut Channel: Patented technology maximizes perimeter weighting by moving the center of gravity lower and farther back in the club head enlarging the hitting area and stabilizing the club head for more forgiveness. Callaway Golf Technologies: Patented Callaway Golf technologies including S2H2, Tru-Bore and VFT Technology Improve efficiency and feel while taking forgiveness to never before imagines levels Constant-Width Sole: Designed to reduce digging on fat, heavy or chunked shots, the constant-width sole helps the iron move smoothly and easily through the turf.
