ABSTRACT:
A power grip insert attachable to a handled instrument or to a user's hand, with one side contoured to accommodate the handle shank to be gripped, and an opposing side contoured in accordance with the musculature of hand palm. The palmar surface area includes dished areas for supporting the thenar and hypothenar eminences, and another depressed area into which the finger tips fit when clenching the instrument handle and grip insert together in the fist. Yet another contoured edge surface permits the thumb to close in cooperation with the fingers and effect a power grip around both the instrument handle and the grip insert.
