The present invention relates to an improved wood-type golf club. More particularly, it relates to a golf club which is designed to give the golfer maximum margin of error in making contact with the club head and the ball to obtain a straight trajectory on the ball. The shaft and the club head are so aligned that if the center line of the shaft is extended it will intercept a plane positioned perpendicular to the base of the club head and pass through the center of gravity of the club head. The striking face of the club head has a number of horizontal corrugations, ranging from 1/64 to ⅛inch in depth, which act as knuckle to strike the ball. The striking face of the club tapers inward from the bottom to top at an angle between about 10°to 15°. The area of the face nearest the toe of the club head is tapered inward toward the rear of the club head to compensate for side spin that would otherwise be imparted to a ball hit in the toe area. The club head is equipped with corrugations or runners 1/64 to ⅛inch in depth on the base thereof to aid in keeping the club straight if the bottom of the club comes in contact with the ground prior to hitting the ball.

A wood-type golf club comprising a club head and a club shaft, said club head and shaft joined so that the center line of the shaft, when extended, intercepts a vertical plane within the confines of the club head which is perpendicular to the base of the club head and passes through the center of gravity of said club head, said club head having a striking face and a base portion, said striking face having a plurality of parallel corrugations thereon, ranging from 1/64 to ⅛inch in depth, said corrugations positioned parallel to said base, one of said corrugations positioned at the bottom of the striking face, said striking face tapering outward from the top to the bottom of the face at an angle of from about 10°to about 15°, said club having a toe and heel portion, 25 to 50 percent of the surface of said striking face positioned nearest the toe portion tapered inward toward the back of the club head, at an angle between about 6°and about 12°to form two separate, substantially planar ball-striking surfaces on said striking face, the base portion of said club head consisting of a plurality of parallel runners thereon, said runners positioned parallel to the direction that the club would travel to strike a ball.
