#650 Bahco Scraper is used for removal of paint, glue and varnish from all surfaces and for smoothing wood. The reversible tungsten carbide cutter has a very slight arc from end to end, so that it cuts 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 resharpened by lapping the back of the blade on a #1200 grit diamond stone.
