The Ultimate Scraper Blade's patented skirted design deflects flooring materials from entering the blade clamp, which prevents damage to the tool. Made from premium grade stainless steel, 0.040-inch thick, hardened, and tempered for maximum toughness and superior sharpness, this allows for longer strokes and fewer blade changes, which leads to FASTER floor removal with LESS work and no more broken blades and damaged tools to replace. The Ultimate Scraper Blade is available in 4-inch and 8-inch sizes.
