Abstract: The present invention is a golf club which induces proper grip and suitable swing by removing the thumb-covering portion of a golf glove so as to extend the Skin Contact Length between the thumb and forefinger. Due to the absence of a thumb covering, structural problems with the glove covering stretching from the thumb area toward the palm may arise when centrifugal force is imparted by the golf club. If the glove covering has been stretched, the covering will become folded when the club is gripped; this causes a pull on the left thumb when gloves are worn and leads to improper grip. Therefore, in order to provide elasticity with regard to stretching, in place of sheepskin the area subject to stretching is processed with a Spandex material having excellent elasticity and flexibility.
