Operating Instructions

This section guides you through the process of sharpening a knife using the Sunicon system.

1. Securing the Knife

1. Loosen the butterfly screw on the knife clamp.
2. Carefully insert the blade of your knife into the clamp, ensuring it is centered and held firmly.
3. Tighten the butterfly screw by hand until the knife is securely fixed and cannot move or shake.

2. Selecting and Attaching the Whetstone

1. Choose the appropriate grit whetstone for your sharpening needs. Start with a coarser grit (e.g., 120# or 320#) for dull knives or repairing edges, and progress to finer grits (e.g., 600# or 1500#) for refining and polishing.
2. Attach the selected whetstone to the guide rod. Ensure it is securely fastened.

3. Adjusting the Sharpening Angle

1. The sharpener allows for angle adjustment from 5° to 90°. Adjust the angle by manipulating the vertical rod and securing it with the appropriate knob.
2. For most kitchen knives, an angle between 15° and 20° per side is common. Refer to your knife manufacturer's recommendations if available.
3. Ensure the whetstone makes even contact with the blade's edge at your desired angle.

4. Sharpening the Blade

1. Apply a small amount of water to the whetstone (if it's a water stone) or use a honing oil (if recommended for your stone type).
2. Using light, consistent pressure, slide the whetstone along the blade's edge, moving from the heel to the tip. Maintain the set angle throughout the stroke.
3. Perform an equal number of strokes on both sides of the blade. The 360° rotation flip design allows you to easily flip the knife to sharpen the other side without removing it from the clamp.
4. Continue sharpening until a burr forms along the opposite edge of the blade.
5. Progress to finer grit stones, repeating the process with lighter pressure, until the desired sharpness is achieved.
6. After sharpening, carefully remove the knife and clean any residue.

Maintenance

• Cleaning: After each use, clean the sharpening frame and whetstones. Wipe the stainless steel frame with a damp cloth. Rinse whetstones under running water to remove metal particles. Allow all components to dry completely before storage.
• Storage: Store the sharpener and whetstones in a dry place to prevent rust and damage.
• Whetstone Care: Over time, whetstones may develop grooves or become uneven. Use a flattening stone (not included) to maintain a flat sharpening surface.

Troubleshooting

• Knife not getting sharp:
  • Ensure the correct sharpening angle is set for your knife.
  • Verify that you are using the appropriate grit sequence (coarse to fine).
  • Check if the whetstone is making full contact with the blade's edge.
  • Ensure sufficient pressure is applied, especially with coarser grits, but avoid excessive force.
• Knife slipping in clamp:
  • Tighten the butterfly screw firmly by hand.
  • Ensure the blade is clean and free of oil or grease before clamping.
• Uneven sharpening:
  • Ensure consistent pressure and an equal number of strokes on both sides of the blade.
  • Check if the whetstone surface is flat.
