Abstract: Medical devices used to assist walking by helping to support a user's weight comprise a series of elements angled with respect to each other at angles selected to honor certain normal anatomical relationships so as to provide a stable platform for supporting a user's weight while reducing injury. Optional additional elements provide cushioning and stability.

Abstract: An ergonometric handle is shaped so as to encourage a natural working grip, thereby increasing user comfort and enabling a user to use a tool incorporating said handle for a longer period of time with reduced fatigue to the tissues, nerves, tendons and bones of the hand. The handle may be angularly disposed relative to the long axis of the tool and the ends of the handle are smaller in width than the middle in order to accommodate the smaller gripping circumferences of the index and small digits. Thus the cross sectional shape of the handle is oblong and when viewed from the side is humpbacked. The grip honors the varying ratios of the digits to the metacarpals. The handle also has indentations in it to enhance the placement of the digits in the natural gripping position. These indentations form a hand imprint in the handle.
