Patent attributes
A front of the club head consists of a round opening that accepts a corresponding round member on the end of the shaft. The face of the club inside the round opening on the club head as well as the face of the shaft member that opposes the face of the club inside the round opening on the club head includes half-spherical divots. Opposing divots are positioned in-line when the shaft is at an allowable angle. A ball bearing inserts into the in-line divots prior to sliding the shaft member into the club head opening to prevent movement when tightened. Inside the club head round opening is a smaller round opening that extends through the back of the club head. The round member on the end of the shaft has an attached threaded post that inserts into the smaller round opening on the club head.
