Definitions

• the present invention relates generally to golf putters.
• the present invention relates to a grip for a golf putter that includes a first portion configured to improve the feel of the putter and a second portion configured to provide a secure and comfortable grip.
• Golf club grips are generally constructed to provide the user with a sure, comfortable grip to the club.
• the gripability and comfort of golf club grips, including putter grips, has generally increased and improved over the past several years.
• a comfortable, easily gripable grip also often serves to isolate the user's hands from the shaft thereby reducing, dampening, or deadening the feel of the putter to the user. Therefore, the desire or need for a comfortable, gripable golf club grip can conflict with the need to sense feedback or the feel of the golf club, particularly a putter.
• a putter grip that includes a portion configured to maximize the feedback transmitted to the user from the shaft and a portion configured to optimize the comfort, softness and tactility of the grip.
• many golf club grips include indicia, which can be applied as a separate coating, or take the form of depressions or raised surfaces formed into the grip.
• the indicia can be graphical, alphanumeric or combinations thereof.
• the coating, depressions or raised surfaces forming the indicia on the grip can negatively affect the gripability, softness or comfort level of the grip.
• the applied coatings, depressions or raised surfaces can provide the grip with an unappealing aesthetic.
• a golf grip that includes the desired amount of indicia without negatively affecting the feel or gripability of the grip. It would be advantageous to provide a golf grip that enables indicia to be formed within or under the grip without negatively affecting the appearance or aesthetics of the golf club. What is needed is a grip that enables indicia, even indicia placed on the butt end of a golf shaft to be seen by the user and others.
• the present invention provides a grip for mounting to a butt end of a golf putter shaft.
• the grip is configured for grasping by a golfer during putting.
• the grip includes an elongate tubular body having a bore extending along a longitudinal axis and an open distal end for receiving the butt end of the golf putter shaft.

• the ratio of the rear transverse thickness to the front transverse thickness is at least five to one.
• a grip is configured for mounting to a butt end of a golf putter shaft and for grasping by a golfer during putting.
