Abstract
A putter has a center of gravity located rearward from the face and under the stroking pivot point. The polar moment of inertia of the putter is increased by moving the distribution of weight toward the rear of the head away from the contact surface. The sole of the putter has an optimized transverse radius and a raised front edge. The putter has an aiming mark that has a minimum area and a minimum length-to-width ratio and is brightly colored. The putter grip has a flat portion that is oriented to match the player's hand rotational position. The face of the putter has friction and energy transfer characteristics that are selected to influence ball motion if struck with stroking errors. The face loft angle cooperates with the face surface characteristics to influence ball launch angle and rotation.
Claims17
A method for selecting a golf putter for use, the putter comprising at least a head with a face and a shaft attached to the head with a grip on the opposite end, the improvement comprising
- identifying that a player's putting stroke error is either misalignment with an aimline or a putter face rotation, and
- matching the stroke error to a putter having the face with a predetermined friction characteristic,
- wherein a low friction face is matched with the error of misalignment with the aimline, and
- a high friction face is matched with the error of face rotation.
A method for selecting a golf putter for use, the putter comprising at least a head with a face and a shaft attached to the head with a grip on the opposite end, the improvement comprising
- identifying that a player's putting stroke error is either misalignment with an aimline or a putter face rotation, and
- matching the stroke error to a putter having a strike face with a predetermined energy transfer characteristic,
- wherein a high energy transfer face is matched with the error of misalignment with the aimline, and a low energy transfer face is matched with the error of face rotation.
A method for selecting a golf putter for use, the putter comprising at least a head with a face and a shaft attached to the head with a grip on the opposite end, the improvement comprising
- identifying a rotational alignment of the putter face with a player's palm position and
- matching an axial flat on said grip to the player's palm, and
- rotating said grip flat on said shaft to produce a low error in putter face rotation.
