Abstract
Abstract A conventional wooden golf club head, contains a pair of parallel air passages beginning at the ball striking area and terminating at the rear of the club. The passages are located substantially midway between the top and bottom surfaces of the head and are spaced from each other, with one passage being located near the toe of the head and one near the heel. A perforated insert occupies each passage and is coplanar with the ball striking surface. The inserts are threadedly engaged with hollow brass tubes which fill the portion of the passageways extending away from the striking surface.
