One tool that should be standard in all woodshops is the scraper. The Sandvik scraper is no ordinary scraper. Having a blade made of Tungsten Carbide, the scraper stays sharp 50 times longer than conventional metal blades. These carbide blades allow the scraper to be used on a variety of surfaces to remove glue, paint, varnish, rust or even bare wood. Both scrapers have blades which are slightly curved on the edges to prevent leaving gouges on the outside of your stroke. The 2.5" model has a reversible blade giving you two edges.
