Tools Youll Need

  • Ruby oil stone (3000 grit for polishing)
  •  Clean cloth or paper towels
  • Water (optional, depending on stone type)
  •  A stable work surface

Step-by-Step Guide

1. Prepare the Stone 
Lubricate the stone Apply a few drops of honing oil or mineral oil to the surface of the ruby stone. This reduces friction, prevents metal particles from clogging the stone, and extends its lifespan.  
2. Set the Sharpening Angle
Determine the blade angle: Most knives have a bevel angle between 15°–25°. Maintain this angle consistently throughout the process. Use an angle guide if needed.  
Secure the knife: Hold the knife firmly with one hand, placing the blade edge against the stone at the correct angle.

3. Grind the Edge  
- If your knife has nicks or a dull edge, start with a lower grit (e.g., 800–1000) to reshape the bevel.  
-Push the blade forward: Using moderate pressure, slide the blade across the stone in a sweeping motion, moving from the heel to the tip. Repeat 5–10 times per side.

4. Polish the Edge 
Switch to a higher grit ruby stone for polishing.  
Reduce pressure: Use light, even strokes to refine the edge. Focus on removing scratches from the coarse grit stage.  
Alternate sides: Polish each side of the blade equally to maintain symmetry.

5. Check Progress
Visual inspection: Look for a uniform, shiny edge under bright light.  
Test sharpness: Carefully slice through paper or a tomato to assess the edge’s smoothness. Repeat polishing if needed.

6. Clean the Stone and Knife
 Wipe the stone with a cloth to remove metal residue and old oil. Store it in a dry place.  
Clean the knife blade with soapy water, dry thoroughly, and apply a light coat of oil to prevent rust.

Tips for Success
Consistency is key: Maintain the same angle and stroke pattern for even results.  
Don’t rush: Polishing requires patience—avoid pressing too hard, as this can overheat the edge.  
- Maintain the stone: Regularly clean and oil your ruby stone to prevent glazing.

By following these steps, you’ll achieve a razor-sharp, polished edge that enhances cutting performance and preserves your knife’s quality. Happy sharpening! If you need the ruby sharpening stone ,please click here.
