A shaft for a putter includes decorative sheaths that may beautify the shaft while retaining lightweight stiffness and avoiding breaking the sheaths.

A golf club is disclosed having a shaft which reduces or dampens vibrations. A method for making the golf club is also disclosed. A cavity is centrally formed within the shaft and a viscoelastic material is disposed within the cavity. The viscoelastic material forms a network of elastic dampeners configured to attenuate propagation of vibrational energy through the shaft.

A golf trainer device comprises a hittable head that is heavier than the head of a standard club combined with a flexible or whippy shaft. In certain embodiments, the head may have at least one flat hitting surface. In some embodiments, the flat hitting surface(s) may be angled with respect to the shaft. In further embodiments, the golf trainer device may have two flat hitting surfaces, which may be symmetrically angled. This enables the device to be used by both right-handed players and left-handed players. The disclosed device may be used for warm-up and training to assist in achieving better ball striking such as a square club face at impact and proper release, amongst other benefits.
