The thin design of the GSR-1 makes it possible to ƒ??go in lowƒ??, inclining toward a flat glass surface. Handle and safety blade cover are made of glass-fiber reinforced PP which is known for its strength, rigidity, and acetone-resistance. Not just the blade, but also the blade holding plate and screw are made of stainless steel to make the glass scraper perfect for use with water and dishwashing liquid. Safety blade cover is also essential while storing.
