Abstract: A putting guide assembly and its associated method of use. The putting guide assembly attaches to the head of a putter. The putter head has a striking surface for striking a golf ball. The putting guide assembly is attached to the putter and presents a flexible guide surface that extends forward of the putter's striking surface. The flexible guide surface can be configured into different curvatures. As the flexible guide surface is adjusted, the perceived curvature observed by a golfer holding the putter changes. A golfer can therefore selectively change the perceived curvature to match the natural curvature inherent in that golfer's putting swing.

Abstract: 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.

Abstract: Technology that allows the angle of the shaft of a golf club to adjust in small increments. The front of the club head consists of a round opening that accepts a corresponding thin round member which can be rotated to a number of positions. The round opening also accepts a corresponding round member on the end of the shaft. This round member slides into the round opening in the front of the club head after the thin round member is seated firmly. A protrusion on the round shaft member will insert into one of the many divots on the opposing face of the thin round member, resulting in an allowable shaft angle.
