Water stones are popular for their fast cutting action. But they need more maintenance than other types of sharpening stones.

  1. Soaking the stone:
    • Soak new stones for 24-48 hours before first use.
    • For regular use, soak for 10-15 minutes before sharpening.
    • Some stones (e.g., Shapton Glass) are splash-and-go and don’t need soaking.
  2. Cleaning after use:
    • Rinse the stone under running water to remove metal particles and slurry.
    • Use a nagura stone or stone fixer to clean the surface if necessary.
    • For stubborn residue, use a mild detergent and soft brush.
  3. Flattening the stone:
    • Use a dedicated flattening plate or diamond stone.
    • Work in a figure-eight pattern to ensure even wear.
    • Flatten after every 3-5 uses or when you notice unevenness.
  4. Drying and storage:
    • Allow the stone to air dry completely before storage.
    • Store in a well-ventilated area to prevent mold growth.
    • Consider using a stone holder for protection and easier handling.

Effective Maintenance Methods for Oil Stones
