A scraper is sharpened by burnishing the edge to form a burr. The key to getting a razor-sharp burr is to start with a perfectly square and smooth edge on the scraper. For this, you’ll need a smooth-cut mill file and a medium oilstone. (The edge of a scraper can damage a soft waterstone.)As shown in photo two, a sharp edge is maintained by angling the file at 45 degrees and drawing down and across the blade simultaneously. Do not change the direction of your file but rather repeat this sequence continuously until the blade is sharp. You are then ready to resume scraping applications.Some people recommend a 85° scraper bevel angle while others favor a 70 or 60° angle. The range seems to be between about 85° (the steepest) to 45° (the most extended) scraper bevel angle.
