			Once your two-handled cabinet scraper becomes dull it will be difficult to run along the surface of your work and will no longer produce shavings. When this starts to happen, it is time to sharpen your tool. The tools that you will need are a mill file, a vice, a clean cloth, oil and a burnishing tool.

			Step 1 – Clamp blade Place the blade in a vice, making sure it is secure, but leaving enough room to be able to do work on the blade

			Step 2 – File blade Remove the old burr (ridge of metal) from the back of the scraper blade with the mill file. Place the file on its side and slide forwards and backwards. Repeat this action until the back of the blade is smooth and no longer has a burr.

			Step 3 – Angle file Use the file at 45 degrees to scrape the bevelled edge of the blade. Push the file away from you and to the side with one sliding motion. Repeat this until the bevelled edge of the blade is clean and smooth.

			Step 4 – File back of blade Again, file the back of the scraper blade to remove any remaining material that may have been created from filing the bevelled edge.

			Step 5 – Check for burr Run your finger over the length and the edge of the blade to make sure there is no burr (rough edge) and the blade is smooth.

			Step 6 – Burnish blade Now grab the burnishing tool with your dominant hand on the handle and your non-dominant hand on the end of the tool. Hold the tool at the angle of the blade, while pushing down hard and across the length of the bevelled blade.

			Step 7 – Finish burnishing Repeat the action in step 6 until there is a “hook” along the back edge of the blade (the higher edge of the bevel). The presence of the hook, or burr, means the process is complete and the blade is ready to be used again.
