Before use, soak both flattening stone and whetstone in water for about 10 to 20 minutes.
Move the ridged side of the flattening stone backwards and forwards over the surface of the whetstone until the flat surface is restored.
Next move the ridged side of the flattening stone over the four edges of the whetstone to round off the corners to prevent cracks or injury.
After use, wash both the flattening stone and whetstone in water, wipe the moisture off and dry thoroughly before storing.
