The Bahco Carbide Scraper is ideal for removal of paint glue and varnish from all surfaces and for smoothing wood. The reversible tungsten carbide cutters have a very slight arc from end to end so that they cut from the center to the end of the blade. This allows the user to achieve a much smoother surface. Bahco carbide blades will last 100 times longer than steel blades and can be easily re-sharpened by lapping the back of the blade on a #1200 grit diamond stone.
