Both edges of a board or a slab can be chamfered at the same time using a metal scraper cut from a hard sheet with a V-shaped blade. Both blades of this scraper must be filed with a fine file, sharpening like this, and then fold it in the same way as the blade of the manual scraper. All kinds of solid wood sticks can be chamfered with the device, as well as the edges of surfaces covered with natural veneers.
