Abstract: A method comprising, in a striking face of a golf club head, the striking face being formed of a first material having a first hardness, creating a plurality of initial grooves, the initial grooves having a first cross-sectional area (A1) and a first pitch (P1) such that A1/P1>0.0030 in. The method continues with modifying the initial grooves at least by positioning a second material in each of the plurality of initial grooves, the second material having a second hardness that is less than the first hardness, such that the first material and the second material form a plurality of final grooves each having a second cross-sectional area (A2) and a second pitch (P2) such that A2/P2

Abstract: A golf club includes a striking face, a top portion, a sole portion opposite the top portion, and a shaft assembly. The shaft assembly can include a shaft having a butt end and a tip end, and a shaft sleeve located at the tip end, the shaft sleeve including indicia. The golf club may further include a hosel extending from the top portion, and the hosel can include a sidewall, a tip end, an internal bore for receiving the shaft assembly, a hosel axis, and an aperture extending through, and circumscribed by, the sidewall such that the indicia of the shaft sleeve corresponds with the aperture. The sidewall circumscribing the aperture may include an inner surface having a first thickness T1 in a radial direction relative the hosel axis and a chamfered edge having a second thickness T2 in the radial direction, T1/T2 being between approximately 3 and 7.33.
