NEW PRODUCT HAS IT ALL!! This kit includes the new stronger model GROUT GETTER with the triangle shape carbide blade, a DIAMOND SHAPE CARBIDE BLADE for non-sanded grout joints, a CHANGING WRENCH and the new 'CORNER PRO' designed for easy access to tile corners, edges, thin grout joints and hard-to-get areas GROUT GETTER To scrape out the grout, simply place one of the three points on the grout to be removed and apply forward pressure. Use the triangle blade for grout joints 1/8” and wider. Remove the grout 1/8” to 3/16” below the surface of the tile for re-grouting. Use the diamond shape blade (which has a sharper point) to remove grout from non-sanded grout joints that are 1/8” and smaller in width. Both carbide blades can be flipped over to use all new cutting edges. CORNER PRO The Corner Pro was developed to assist the Grout Getter tool in scraping out grout and caulking in corners, edges and hard-to-get areas. Thin tile and stone grout joints are no longer a problem. Simply place one of the carbide blade points on the material to be removed and with a mostly pulling motion, scrape out the material. The thin design and different angles of the blade enables the user to reach and scrape corners and edges on countertops, sinks, tubs, floors, showers, just about anywhere!
