An ergonomically efficient knife and implement handle fits the natural curve of the clasped hand and efficiently aids repetitive cutting motions. The handle comprises a major longitudinal rib arcuately extending between spaced-apart integral anterior and posterior ends. The handle is tightly grasped by the curled fingers and palm of the user\s hand. An arch integrally extends along and across the rib between the anterior and posterior ends to define an orifice which receives the user\s thumb and a portion of the user\s palm, and it facilitates comfortable twisting movements of the handle. An anterior hook shaped to coincide with the natural curve of the dorsal surface of the index finger aids in thrusting during repetitive cutting movements. A thumb rest defined at the top of the anterior end of the rib fits the distal phalanx of the thumb. The thumb rest transfers the force of the thumb to the implement. A posterior hook at the rib posterior end engages the naturally curved surface of the hand to ease repetitive retrieval motions. The anterior hook, the anterior thumb rest, the arch, and the posterior hook enable the user to periodically relax his hand between cutting motions without dropping the handle.
