Abstract
Abstract The improved grip is furnished as an adjunct to a tool of the type featuring a horizontal part; e.g., a handle, which carries, for example, a working member such as a rotary slicer operating in a plane parallel to the plane that includes the axis of the handle. The grip is mounted in a position in which it extends upwardly in upright fashion from the aforesaid plane and is mounted on the tool by means including vibration-damping material, which, in conjunction with the upright posture of the grip, minimizes physical tensions in the hand and wrist/forearm of the user. The attachment also includes a rest for the user's wrist/forearm.
