4. Operating Instructions: Sharpening Process

The coarse grit of this stone is primarily for establishing a new edge, repairing damaged edges, or quickly removing material. It will leave a relatively rough edge that requires further refinement with finer stones.

General Sharpening Steps:

1. Determine Angle: Identify the existing bevel angle of your blade or tool. Consistency in maintaining this angle is crucial for effective sharpening.
2. Larapkeun Minyak: Ensure the stone surface is adequately lubricated with sharpening oil.
3. Sharpening Stroke:
   • Place the blade flat on the stone at the desired sharpening angle.
   • Using moderate pressure, push the blade across the stone, leading with the edge, or pull it across, trailing with the edge. Maintain a consistent angle throughout the stroke.
   • Perform strokes on one side of the blade until a burr (a slight wire edge) forms along the entire length of the opposite side. You can detect this burr by gently feeling the edge with your fingertip (exercise caution).

5. Remove Burr: To remove the burr, alternate a few light strokes on each side of the blade, reducing pressure with each pass. You can also use a stropping motion.
6. Sabeulah bersih: Wipe the blade clean to remove any metal particles and oil.
7. Léngkah salajengna: For a finer, sharper edge, proceed to a medium or fine grit sharpening stone (not included) after using this coarse stone.

Specific Tool Considerations:

• péso: Maintain a consistent angle, typically between 15-20 degrees per side for kitchen knives, or 20-25 degrees for outdoor/utility knives.
• Plane Blades & Chisels: These tools often require a very precise, flat bevel. Use a honing guide if necessary to maintain accuracy. Sharpen the bevel side until a burr forms, then lightly flatten the back of the tool on the stone to remove the burr.
• Pangikis: Sharpening scrapers involves creating a burr that is then turned into a hook with a burnisher. The coarse stone can be used to flatten the edges before burnishing.

5. Pangropéa

• Ngabersihkeun Batu: After each use, wipe down the stone with a clean cloth to remove excess oil and metal particles. For deeper cleaning, you can scrub the stone with a stiff brush and sharpening oil or mineral spirits.
• Preventing Glazing: Regular use with oil helps prevent the stone from glazing (a smooth, non-abrasive surface forming due to embedded metal particles). If glazing occurs, clean the stone thoroughly.
• Flattening the Stone: Over time, sharpening stones can develop hollows or become uneven, especially with concentrated use in certain areas. To maintain optimal performance, periodically flatten your stone using a coarser abrasive (e.g., silicon carbide grit on a flat surface like glass) or a dedicated flattening stone.
• Panyimpenan: Store the sharpening stone in its protective case in a dry environment to prevent damage and contamination.

6. Cara ngungkulan

• Blade Not Getting Sharp:
  • Sudut Salah: Ensure you are consistently holding the blade at the correct sharpening angle.
  • Tekanan anu teu cekap: Apply moderate, consistent pressure during the sharpening strokes.
  • Stone Glazed/Clogged: Clean the stone thoroughly and reapply oil.
  • Burr Not Formed: Continue sharpening on one side until a burr is clearly felt along the entire edge.
• Stone Glazing Quickly:
  • Minyakna teu cekap: Ensure you are using enough sharpening oil to float away metal particles.
  • Ngabersihan anu teu leres: Clean the stone regularly after use.
• Uneven Edge:
  • Inconsistent Angle: Practice maintaining a steady angle throughout the sharpening process. Consider using a sharpening guide.
  • Uneven Stone Surface: Flatten the stone if it has developed hollows or an uneven surface.
