Abstract
Described herein are iron golf club heads and sets of iron golf clubs that have variable weight distribution. Each iron golf club head has a cavity and a y-shaped cavity pad disposed on at least a portion of a back wall of the cavity. The y-shaped cavity pad provide reduced vibrations within the cavity when the iron golf club head strikes a golf ball. The y-shaped cavity pad also provides an enlarged sweet spot to provide increased forgiveness for off-center hits. Other aspects, features, and embodiments are also claimed and described.
