Accurate and consistent grip is very important for this. For this reason, it is essential for golfers to learn how to grip the grip correctly and get the right swing posture.

Conventional golf club grips are mostly rounded, so when you hit a golf ball with a golf club, the grip slips in your hand, causing the shaft to rotate little by little. The position has changed and it is difficult and the results are often bad. In order for the grip of the golf club to slip in the hand so that the shaft does not rotate, it is necessary to hit the golf ball exactly at the designated hitting position of the golf club head or to apply the grip of the golf club with great force. However, except for those who play golf very well, the golf ball cannot hit the golf club exactly at the hitting position of the golf club, and the golf ball is held by the force of the hand to prevent the grip from rotating and slipping.
