It is used to manually remove small amounts of material and excels in tricky grain areas where hand planes would cause tear out.Scraping produces a cleaner surface than sanding; it does not clog the pores of the wood with dust, and does not leave a fuzz of torn fibers.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.In use, the card scraper is grasped by the fingers, one hand on either side, and tilted in the direction of travel.In addition to the tilt, the user will usually flex the scraper slightly by holding it at the edges with the fingers and pressing in the centre with the thumbs.Burnishing jigs and other accessories are available to assist in turning the burr, which makes the card scraper more accessible to the novice.
