A novel golf club (10) and associated methodology optimally minimize air resistance during swinging motion of the golf club (10). The golf club (10) comprises a head (12) for striking a golf ball, a handle (18) for swinging the golf club (10) and a shaft (22) connecting the head (12) with the handle (18). A rib (24) protrudes outwardly from the shaft (22) and runs longitudinally along the shaft (22) in a spiral configuration. The spiral configuration has a pitch which decreases from the head (12) to the handle (18). The spiraling configuration of the rib (24) minimizes vortices and drag generated when the golf club (10) is in motion to thereby decrease air resistance to the golf club (10). Furthermore the golf club (10) is provided with a novel head (12) having a body with a face (14) angled inwardly, a rear end (38) angled inwardly, right and left sides decreasing in curvature from the rear end (38) to the face (14), a substantially flat bottom (46), and a top (48) which is circular as viewed from the face (14) and is parabolic as viewed from the right and left sides (42, 44). |
