3. Nastavení

1. Příprava: Ensure your workspace is stable and well-lit. Place the sharpening stone on a non-slip surface.
2. Mazání: This oil stone is designed to be used with sharpening oil. Apply a generous amount of Norton Abrasives Sharpening Stone Oil (or a suitable alternative) to the surface of the stone before sharpening. This prevents the stone from clogging with metal particles and ensures efficient cutting action.
3. Kontrola nástrojů: Before sharpening, inspect the tool or blade for any nicks, burrs, or significant damage. The coarse grit of this stone is suitable for addressing these issues.

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. Naneste olej: 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).
4. Opakujte na druhé straně: Flip the blade and repeat the process on the other side until a burr forms on the first side.
5. Odstranění otřepů: 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. Čistá čepel: Wipe the blade clean to remove any metal particles and oil.
7. Další kroky: For a finer, sharper edge, proceed to a medium or fine grit sharpening stone (not included) after using this coarse stone.

Specific Tool Considerations:

• nože: 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.
• Scrapers: 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. Údržba

• Čištění kamene: 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.
• Skladování: Store the sharpening stone in its protective case in a dry environment to prevent damage and contamination.

6. Řešení problémů

• Čepel se neostří:
  • Nesprávný úhel: Ensure you are consistently holding the blade at the correct sharpening angle.
  • Nedostatečný tlak: 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:
  • Insufficient Oil: Ensure you are using enough sharpening oil to float away metal particles.
  • Nesprávné čištění: Clean the stone regularly after use.
• Nerovný okraj:
  • 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.
