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.

An ergonometric handle comprising a gripping surface shaped to encourage a natural working grip, having a connecting end and a free end defining the limits of a longitudinal surface, said surface encompassing a longitudinal axis of said ergonometric handle, and further comprising a thumb indentation within said surface of sufficient length to accommodate a user\s thumb from the interphalangeal joint to the tip within said thumb indentation, further comprising an indentation within said surface of sufficient length to accommodate a user\s digit from the proximal interphalangeal joint to the tip, wherein said thumb indentation is formed at an angle from the longitudinal axis of said ergonometric handle of approximately 20 degrees, and wherein said digit indentation is formed at an angle from the longitudinal axis of said ergonometric handle of approximately 30 to 60 degrees.
