发明名称 Golf club
摘要 A golf club comprising a clubhead with a sole profile shaped in an inverted peak roof, the clubhead having a line of centers of percussion which intersects the sole at the peak and which runs through the centroid of the clubface. The line of centers of percussion is marked on the clubface replacing the conventional icon so as to provide a visual indication to the golfer of the points of impact on the clubface from sole to crown which produce minimal shaft twisting upon contact with the ball. Upon contact with the ground, the clubhead presents a single point of contact located on the line of centers of percussion and shaft twisting due to ground contact is also minimized.
