The cutting component of a card scraper is the [[Burr (metal)|burred]] edge of the scraper. The burr is a sharp hook of metal which is turned on the edge of the scraper by burnishing with a steel rod. A [[file (tool)|file]] or [[sharpening stone]] is used to [[jointing (sharpening)|joint]] the edge of the scraper before burnishing. Cabinet makers typically joint the edge square, or at a right angle to the face of the scraper, which allows a fine burr to be turned on both sides. [[Luthier]]s often use a [[bevel]]ed edge, which allows a more aggressive burr, but on one side only.
