ABSTRACT:
A golf club is provided which will enable a golf player to easily determine when he has executed an improper swing known as a "twist swing". The golf club of the present invention is characterized by a hollow, circular readily flexible shaft provided with a conventional wood or metal club head at one end and a grip at the other end with a flexible, thin, flat metal leaf or strip fixedly positioned within the hollow shaft for substantially its entire length with the width thereof corresponding to the internal diameter of the shaft. The metal leaf is placed in an alignment with the shaft such that when a "twist swing" is created the metal leaf will be torsionally twisted along its longitudinal axis and will create a rubbing sound and cause vibration to the shaft.
