ABSTRACT:
A hand-held instrument has a variable contour grip, a main body having a grip-attaching portion, and a tubular grip body made of a resilient material and mounted around the grip-attaching portion of the main body for undergoing rotation relative thereto. Each of an outer circumferential surface of the grip-attaching portion and an inner circumferential surface of the grip body has a non-circular cross-sectional shape so that when the grip-attaching portion and the grip body are rotated relative to one another, the grip body undergoes deformation so that portions thereof or contracted and other portions thereof are expanded to thereby change an outer configuration or contour of the grip body.
