Sharpening Scrapers
Cabinet or Card Scrapers - Sharpen the edge of cabinet scrapers with the tool guide bar set to a 90 degree angle. Rotate the tool guide bar so the scraper may be positioned in front of and rest against the flat portion of the bar. The flat of the tool guide bar will support the scraper vertically as the abrasive disc rotates. Hold the flat sides of the scraper on the abrasive surface and polishing both sides along the cutting edge. Roll a burr along the edge with a burnishing tool.
