Abstract

The surface is incorporated into the case during moulding, if it is of plastic and for metal cases it is applied as a plastic coating. It covers only the grip handle and the sides and improved friction characteristics make the tool less liable to slip in use or to slide when placed on an inclined surface. Any minor imperfections in a moulded case are less discernible, resulting in cheaper production costs. The improvement applies to any portable motor driven tool, and the surface may simulate or be a grid of projecting lines.
