发明名称 Golf club
摘要 A golf club for effecting shots within sixty yards of play to the "green". The golf club includes two distinct shaft configurations and has a club head with a striking face or impact surface which gradually narrows downwardly to a rounded bottom edge to form a convex shaped structure having a series of cavity contours for effecting different degrees of impact with a target. The convex top surface of the golf club head has a series of seven colored parallel grooves incorporated thereon to form an optical pattern to help a golfer's eyes focus and to project a more broad-based target line-up. The angle between the line-up defined by the shaft when positioned normally as during play and a line perpendicular to the ground is six to seven degrees.
