Provided is an adjustable custom grip and method of forming the same are provided. The method of forming a customized putter grip includes orienting a first grip member having a first contact surface and a second grip member having a second contact surface of the customized putter grip in a predetermined orientation selected from a set of angles between the first contact surface and the second contact surface. The method may also include fixing the first grip member and the second grip member in the predetermined orientation. The method may further include coupling the customized putter grip with fixed first grip member and second grip member to a shaft of a putter. The custom grip provides for an anatomically, ergonomically custom putter grip to accommodate variations in human hands and other anatomical parts that affect the holding of a golf club grip.
