5.2 General Sharpening Procedure

1. Prepare the Tool: Clean the tool to be sharpened.
2. Set the Angle: Use the angle guide and the universal support arm to set the correct sharpening angle for your tool.
3. Mount the Tool: Secure the tool in the appropriate jig (e.g., clamping jig for chisels, knife sharpening jig for knives).
4. Grinding: Gently bring the tool's edge into contact with the rotating wet grinding wheel. Apply light, consistent pressure. Move the tool smoothly across the wheel to ensure even sharpening. The water will keep the tool cool and prevent bluing of the edge.
5. Check Progress: Periodically check the edge for sharpness and consistency. Continue grinding until a burr forms on the opposite side of the edge.
6. Deburring/Honing: Once the burr is formed, switch to the leather honing wheel. Apply a small amount of honing compound to the leather wheel. Gently run the tool's edge against the honing wheel to remove the burr and polish the edge.
7. Final Check: Inspect the sharpened edge. It should be clean, sharp, and free of burrs.
