The hand grip (2) has two grip pieces (4) extending laterally from a guide arm (1). The grip pieces with their outer ends are angled downwards from a horizontal position for the arm. The extend of this downward angle is 11 deg.. In this way, a more natural work position for the hands is achieved without the straining of the muscles of the upper side of the lower arm which happens with a wholly horizontal hand grip. |
