Abstract
A golf club is provided including a club head having a toe portion, a heel portion including a shaft receiving bore, a face for striking a golf ball, a center of gravity and a sole. The shaft includes a proximal end and a distal end. The distal end is received in the shaft receiving bore of the heel portion of the club head. A grip is connected to the proximal end of the shaft. The connection of the shaft and club head is characterized by the shaft having a distal end or tip that is cut at an angle of between 5.degree. and 85.degree. and more preferably 30.degree. and 45.degree. relative to a longitudinal axis of the shaft. Similarly, the shaft receiving bore is blind and includes a bottom wall adjacent the sole of the club head. This bottom wall extends at an angle to a longitudinal axis of the bore matching the distal end or cut angle of the shaft. Further, the bottom wall of the bore is positioned vertically below a plane extending through the center of gravity of the club head and parallel to the ground when the club head is positioned to strike a golf ball with the sole resting on the ground. A method for producing the golf club is also provided.
