Product Details

A whetstone is considered by many chefs to be the best way to sharpen knives. A Japanese ceramic-bonded stone removes the least amount of metal from a knife and will not easily wear out. However, over time, as you use a whetstone, it is normal for uneven, concave areas to develop. This Kai Seki Magoroku Levelling Stone will restore the surface of the whetstone so it is perfectly flat and good as new.

After soaking both the whetstone and the levelling stone, you move the ridged side of the flattening stone backwards and forwards over the surface of the whetstone until the flat surface is restored. The grooves in levelling stone help collect the material removed from the whetstone as you work. Once completely flat, pass the levelling stone over the four edges of the whetstone, creating a bevelled edge to prevent cracks or injury.
