An ergonomic putty knife and scraper handle manufactured from at least two different hardness injection molded polymers having a plurality of harder longitudinal ribs embedded in a softer overlay but exposed on both top and bottom surfaces in strategic locations. The longitudinal ribs providing non-binding contact with fabric surfaces to ease the insertion and removal of the handle into and from a user's pocket for temporary storage of the tool when not in use. When employing the tool for its intended purpose, however, the user enjoys the comfort, efficiency and safety of an ergonomic handle offering a "soft touch" to thumb and fingers in those locations requiring superior grippability.
