  • Patent number: 10857431
    Abstract: Golf club heads include an iron type golf club head body having a rear surface (e.g., a perimeter weighting member) that defines a first weight receiving portion, and a weight member is mounted in the first weight receiving portion. The club head body further defines a second weight receiving portion independent of the first weight receiving portion, and a second weight member is removably engaged with the golf club head body at this second weight receiving portion. The weight members may be interchangeably mounted in the two weight receiving portions to thereby allow selective placement of the center of gravity characteristics of the club head body. Golf clubs including these club heads and methods of making such golf club and golf club heads also are described.
