The Hyper Tough Glass and Tile Scraper Kit can be used for a variety of scraping purposes on glass, tile, metal, flooring and other flat surfaces. The soft-grip 4-inch glass & tile scraper contains a patented easy push button opening and locking mechanism to safely change the blade. Included are five 4-inch universal replacement blades. The blade can also be used with a 3.5-inch tool as it can be broken along the score line. The Safety Glass Scraper is a heavy-duty, all-steel retractable scraper with a soft-grip used for scraping residue from glass, tile, metal, and other hard, flat surfaces. Fully extend the slider to remove and change the blade and simply retract the blade back into the scraper for safe keeping. Included are 5 individually wrapped single edge blades in a patented, plastic dispenser.
