Abstract: This invention is a kit and method for testing golf balls to determine if the center of gravity is the center of the golf ball. The kit uses a liquid, such as water, having a densifying agent to increase the density of the liquid solution so a golf ball will float when placed in the solution. A wetting agent is also included in the solution to decrease the surface tension. If a golf ball, having a center of gravity at other than the center of the golf ball, is placed in the solution, the light side of the ball will rotate to the top. The light side is then marked with an indelible marker. An axis through the center of the golf ball and the mark also includes the center of gravity of the golf ball. Thereafter, the axis of the golf ball including the mark, should always be placed perpendicular to the plane of the striking surface.
Abstract: A blade type golf club comprising an upstanding blade and a rearwardly extending flange, a longitudinally and horizontally extending groove of desired depth in the angle formed between said blade and said flange and extending forwardly into said blade, and an arcuately shaped groove of desired depth in the medial upper surface of said flange and intermeshed with said longitudinally and horizontally extending groove.
