Abstract
A scraper blade has at one end a scraper tip and at the other end a mounting base. The scraper tip is outwardly tapered. The scraper blade has at least two layers of different materials. The layer of material which is facing forward, i.e. that first meets the surface to be scraped, and which is adapted to form the actual scraper tip is made of a material which is both softer and more abrasion resistant that said other layer.
