Either end of the Scrigit Scraper can be restored to its original condition by using an emery board or very fine sandpaper. Hold the scraper against the sandpaper at the same angle as the original angle of the end be sanded. Be careful to keep the newly sharpened scraper end away from fingers and other body parts when in use. If the scraper ends are too badly worn or damaged, then replace the scraper for best results.
