A handle is applicable to a wide variety of apparatuses, equipment and devices found in industry, commerce, in the home, or for exercise or recreational purposes. The handle may be fashioned integrally with the apparatus or as a retrofit attachment therefor. In using the handle, the person\s hand is inserted through an opening and into a chamber formed between the inner and outer walls of the handle. The palm of the person\s hand substantially rests on the convex inner surface of an inner wall of the handle, while the back of the person\s hand substantially confronts the concave inner surface of the outer wall. With this arrangement, the user\s hand is maintained substantially in a curved natural “at rest”position, rather than being tightly closed, so that a forceful grip is no longer necessary. As a result, the human effort and energy required to manipulate or control the associated apparatus, equipment or device is substantially reduced, thereby substantially reducing the fatigue normally associated therewith. Moreover, in certain applications (such as portable power tools) the handles provide an enhanced safety feature.

In combination with an apparatus having an existing handle, an auxiliary handle for the apparatus and means to detachably attach the auxiliary handle to the existing handle of the apparatus; such that when attached, the auxiliary handle is rigidly secured to the existing handle and is disposed radially outwardly of the existing handle, wherein a forceful grip is not required for the manipulation or control of the apparatus, the auxiliary handle being substantially unitary and rigid and having respective inner and outer walls defining a chamber therebetween, the auxiliary handle having an opening formed therein and communicating with the chamber for providing access for the user\s hand, the chamber being closed internally of the auxiliary handle and limiting the degree of insertion of the user\s hand through the opening and into the chamber, such that the user\s hand is disposed in the chamber between the inner and outer walls of the auxiliary handle, the inner wall having a substantially convex inner surface, and the outer wall having a substantially concave inner surface, such that the palm of the user\s hand substantially rests on the convex inner surface of the inner wall, and such that the back of the user\s hand substantially confronts the concave inner surface of the wall, so that the user\s hand is substantially in a curved natural at rest position rather than being tightly closed, thereby substantially reducing the human effort and energy required to manipulate or control the apparatus, and thereby substantially reducing the fatigue normally associated therewith and the existing handle of the apparatus being disposed radially inwardly of the inner wall of the auxiliary handle and being nested therein, such that the weight concentration of the existing handle is aligned radially with respect to the auxiliary handle and the user\s hand therein.
