Kasumi Combination Ceramic Whetstone 440/1000 Grit

Before use, soak the whetstone in water for 10 to 15 minutes or until air bubbles cease, indicating the stone is fully saturated. This prevents excessive wear on the stone and helps with smooth sharpening.

• Use the 440-grit side to reshape and restore dull or damaged edges. Hold the knife at a consistent angle (typically 15° to 20°) and gently slide the blade across the stone, maintaining light pressure. Repeat several times on both sides of the blade.
• After reshaping, turn the stone over to the 1000-grit side to refine and hone the edge.
• Continue sharpening with a similar technique to further smooth and polish the blade edge for a sharp, functional result.
• After use, wipe the blade with a clean cloth to remove any debris or water.
