The Scraperite scraper system consists of plastic razor blades and one blade holding tool to put the razor in. What makes Scraperite truly unique is that the plastic razor blades come in a variety of tensile strengths, ensuring that you have the right tool for the job. Unlike conventional metal blades, our blades will not scratch surfaces. This is extremely important when working on fragile, easily scratched surfaces, like hard wood floors and your cars paint job. Just try our blades once and you will see the difference.
