Variable contour grip

A hand instrument with variable grip arrangement comprising:

• an instrument body of the type to be held between the fingers of the hand for use, the body having an active end and an opposite end;
• a resilient material forming a grip around the body near the active end;
• radial expansion means in the body and under the grip for expanding radially for expanding the grip into an expanded ergonomic position and for contracting radially for contracting the grip into a contracted storage position;
• movable actuation means engaged with the radial expansion means for moving the radial expansion means between the expanded and the contracted positions;
• the expansion means comprising at least three bendable cantilever beams in the instrument body which are circumferentially spaced inside the grip and which are bent outwardly by the movable actuation means, and an inclined bending surface in the body engaged with a free end of each beam for bending each beam radially outwardly when each beam moves axially along the inclined surface;
• and
• bendable slide means between the bendable cantilever beams and the grip for allowing relative sliding between the beams and the grip.
