Unger supplies scrapers and blades for all applications. The glass scrapers are equipped with a double edge blade. Perfect for removing stickers, cement residues etc. from glass surfaces. These blades are available in heavy duty carbon or high quality flexible stainless steel. Surface scrapers are equipped with an extremely solid and stable interchangeable blade. The sharp side is ideal for removing tough dirt (e.g. paint residue or stickers). The edge-free side is suitable for removing harder residues (e.g. glue, cement, concrete debris etc.).
