发明名称 Sports shaft with variable contour
摘要 The present invention relates to an improved sports shaft. The improved shaft is comprised of a synthetic material designed to minimize weight and provide other desirable characteristics. The shaft may include a unique outwardly expanded portion that dramatically improves the shaft's performance. The outwardly expanded portion expands lengthwise and widthwise to create a wider portion that accommodates a player's hand position. The outer surface of the shaft may be coated with a gripable material to improve the overall grip and feel characteristics of the shaft.
