Sports equipment handle having tactile biofeedback reference feature

Abstract

A sports equipment handle that provides a user with tactile biofeedback is provided. The handle includes a handle body having an upper portion, a lower portion, a grip length, a proximal end, a distal end, and an exterior body surface. The exterior body surface is defined by a first octant, a second octant, a third octant, a fourth octant, a fifth octant, a sixth octant, a seventh octant, and an eighth octant. The handle includes at least a first tactile reference indentation that extends longitudinally along the exterior body surface and is confined to a first tactile octant. The first tactile reference indentation is formed with dimensions specifically tailored to harness the user's natural attributes of sensibility, proprioception, and neuromuscular memory to improve a user's accuracy.
