Abstract
An improved wood type golf club is disclosed. A reinforcing member is provided in the club whereby the strength of attachment of the shaft to the club is greater than with conventional wood type clubs. Additionally, because of the shape of the reinforcing member, a portion of the weight of the club head can be moved out to the peripheral regions thereof thereby providing a greater moment of inertia and a correspondingly better club. Furthermore, by means of providing edge radii of at least 0.15 inches and 0.25 inches on the bottom and top leading edges respectively of the face of the club and with a "trip step" there is a marked reduction in wind resistance thus lowering the power needed to swing the club or increasing club head velocity for equal energy input.
