The Hesacore grip features a multifaceted design that expands the contact surface between the hand and the handle. This design is claimed to increase grip strength by 8% to 14%, depending on the overgrip used.

Proponents of the Hesacore grip suggest that the increased grip allows players to hold the handle with less effort and finger contraction, while still maintaining a secure grip. This potentially leads to a more relaxed and fluid swing, as excessive muscle tension in the hand, wrist, and forearm can hinder efficient energy transfer to the ball.

Users of the Hesacore grip report experiencing improved control, feel, and power in their shots. However, it is important to note that individual experiences may vary, and factors like playing style, technique, and personal preference can also influence performance.
