Abstract
Abstract A hand grip comprised of an elastomeric material is coaxially secured to the end of a golf club shaft. The grip includes five flat gripping surfaces which extend longitudinally over a substantial length and which are equally spaced around the grip. The outer surface of the grip formed by the gripping surfaces has a substantially regular pentagonal cross section. One of the flat surfaces is located on the upper surface of the grip to directly underlie the golfer's thumbs when properly gripping the club.
