Thin strips of lead with an adhesive backing are used to add weight to clubheads to increase swing weight. The angle formed by the centerline of the shaft and the ground line. The angle of the clubface in connection with the ground line. Measured in degrees. The higher the number of degrees, the more loft the club has and the higher the shot trajectory.
Iron clubheads whose face height are lower than standard.
A tapered steel spindle used to form graphite or composite shafts. The strips wrapped around the mandrel form the shaft. A set of golf clubs designed to look and respond the same.
