To effectively sharpen your knives, the stone must be completely flat and straight. Regular use of the flattening stone will keep your stone in good condition and ready for proper sharpening.

Usage Instructions:

• Soak both the flattening stone and the sharpening stone in water for about 10 to 20 minutes before use.
• Move the ridged side of the flattening stone back and forth over the surface of the sharpening stone until its surface is completely flat.
• Move the ridged side of the flattening stone over the four edges of the sharpening stone to round off the corners to prevent chipping or injury.
• After use, wash both stones with water, wipe them, and dry them thoroughly before storing them.
