The time required to achieve optimal sharpness with the Samura 240/800 combination whetstone depends on the condition of the knife, but with regular use, it usually takes between 10 and 20 minutes. The 240-grit section is for the initial rough sharpening of dull blades, while the 800-grit section provides the finer, working edge.
Tips for beginners: - Soak the stone in water for about 5 to 15 minutes before use, until no more air bubbles rise to the surface.
- Maintain a constant sharpening angle of approximately 15 degrees; a coin placed between the spine of the blade and the stone can be used as a guide.
- Guide the blade across the stone with light, even pressure, ensuring the surface remains moist to create a slurry that promotes sharpening.
- Use a non-slip mat for maximum stability and safety during the sharpening process.
