Abstract
A scraper in combination with a sharpener provides consistent sharpening of the scraper blade. The scraper has a scraper blade, blade holder, and bearing surface. The sharpener has a sharpening element and a guide generally parallel to the sharpening element. The bearing surface of the scraper fits the guide of the sharpener and the scraper blade contacts the sharpening element. The scraper can be drawn along the guide to draw the blade along the sharpening element. The bearing surface and guide keep the blade in consistent and correct relation to the sharpening element to provide proper sharpening of the scraper blade. Adaptors may be used to sharpen additional types of blades or tools on the sharpener and different types of sharpening elements may be used in the sharpener.
