  • Patent number: 10328317
    Abstract: Embodiments of golf clubs with adjustable loft and lie and methods of manufacturing golf clubs with adjustable loft and lie are generally described herein. The invention relates in particular to a golf club head with an adjustment portion that allows a user to change the loft and lie. The separate adjustment portions of the club head can couple the upper hosel to the body at a plurality of positions. An insert part of the adjustment portion has an upper section for receiving the upper hosel portion, a middle section, and a lower hosel portion. The sections of the adjustment portion can be coupled together by a fastener so that the sections are rotationally moveable.

  • Publication number: 20190151720
    Abstract: A golf club head includes a body having a crown opposite a sole, a toe end opposite a heel end, a back end, and a hosel. The golf club head also includes a club face having a loft below a loft threshold in which increasing a coefficient of friction between a golf ball and the club face decreases the spin imparted on the golf ball after impact with the club face. A surface feature positioned on a portion of the club face is configured to increase the coefficient of friction between the golf ball and the club face.
