Abstract
A set of golf iron clubs is disclosed that, through unique structural features, provides excellent playing characteristics and enhances a player's ability to play accurate shots. Each club in the set has a head with a face angle of at least 1/2.degree. and a concentration of mass formed within the head. Face angles decrease sequentially from the longest iron in the set to the shortest iron in the set, while the Concentrations of mass also vary sequentially in location from a high heel location in the longest iron to being disposed further toward a sole and toe location in the shortest iron. The face angles are preferably at least 1.degree., more preferably in the range of 1/2.degree. to 5.degree., and most preferably in the range of about 1.degree. to about 31/2.degree.. Also disclosed are the individual clubs in the set. The shaft grip of each club also incorporates a reminder for enabling a golfer to maintain the striking face in proper alignment with the golf ball.
