5. Setup Instructions
- Secure the Clamping Base: Attach the clamping base to a sturdy countertop or workbench using the main body screw. Ensure it is tightened firmly to prevent any movement during sharpening.
- Assemble the Main Frame: Connect the main sharpener frame to the clamping base.
- Insert Sharpening Rod: Insert the sharpening rod into the angle adjustment mechanism on the main frame.
- Attach Sharpening Stone: Select the desired sharpening stone (e.g., 240# for coarse sharpening) and attach it to the end of the sharpening rod.
- Secure the Knife: Place the knife blade into the knife clamp on the sharpener's main frame. Use the screw tool to fix the knife securely in place.


6. Operating Instructions
- Adjust Sharpening Angle: Use the angle adjustment mechanism to set the desired sharpening angle for your knife. The system is designed for constant angle grinding, ensuring precision.
- Sharpen One Side: With the chosen sharpening stone attached, gently slide the stone along the blade edge, maintaining consistent pressure. Perform several passes until a burr forms on the opposite side of the blade.
- Utilize 360-Degree Flip: The sharpener features a 360-degree flip design. Once one side is sharpened, simply flip the knife clamp to sharpen the other side without removing the knife. This ensures symmetry and efficiency.


- Progress Through Grits: Start with a coarse grit stone (e.g., 240#) for dull blades, then move to medium (e.g., 800#), and finally fine grit (e.g., 2000#) for a razor-sharp edge. Finish with the leather strop for polishing and burr removal.
- Check Sharpness: Periodically check the blade's sharpness. The system allows for convenient handheld checking of the blade's sharpness at any time for adjustment.

The Rieci RC-002A is versatile and can sharpen various knife types, including large and small, thin and thick blades.

7. Maintenance
- Clean Sharpening Stones: After each use, clean the sharpening stones with water and a brush to remove metal particles and maintain their effectiveness.
- Wipe Down Components: Wipe all metal components of the sharpener with a clean, dry cloth to prevent rust and corrosion.
- Lubrication: Periodically apply a small amount of light machine oil to moving parts and screw threads to ensure smooth operation.
- Storage: Store the sharpener and its accessories in the provided storage case in a dry, cool place to protect them from dust and damage.
8. Troubleshooting
- Blade Not Getting Sharp:
- Ensure the correct sharpening angle is set for your knife.
- Start with a coarser grit stone if the blade is very dull.
- Apply consistent, light pressure during sharpening.
- Ensure the sharpening stone is clean and not clogged with metal particles.
- Scratches on Blade Surface:
- Progress through grits properly, starting coarse and finishing with fine.
- Ensure the blade and stones are clean before sharpening.
- Use lighter pressure with finer grit stones.
- Sharpener Feels Unstable:
- Verify that the clamping base is securely fastened to a stable surface.
- Check all screws and connections on the main frame and knife clamp are tightened.
9. User Tips
- Practice Makes Perfect: If you are new to knife sharpening, practice on an old, less valuable knife first to get a feel for the system and angles.
- Use Water/Honing Oil: For best results and to prevent stones from clogging, use water or honing oil (depending on the stone type) during the sharpening process. Keep the stone surface wet.
- Consistency is Key: Maintain a consistent angle and pressure throughout the sharpening stroke for an even and sharp edge.
- Burr Formation: Sharpen one side until you feel a slight burr (a tiny wire edge) along the opposite edge. This indicates you've reached the edge. Then, flip and sharpen the other side until a burr forms there.
