How to Use
Before Use
- No soaking is needed, but soaking for 5-10 minutes would produce a better result if you prefer a softer, gentler surface.
- Splash water onto the surface before sharpening. If the stone feels dry, apply more water as needed.
After Use
- Do not keep soaking after use.
- Store in a dry, well-ventilated area to prevent cracking or warping.
Additional care
- Flatten the stone periodically using a lapping plate or stone fixer to maintain a level surface. Use light, even strokes to avoid unnecessary wear on the stone.
