Naniwa Flattening Stone for Whetstones (large) - #220
Whetstones are worn unequally (depending on their use) and in time they become more and more hollow. Despite a good grinding technique, a hollow stone is an inefficient tool, and in extreme cases can cause some damage to the blade of the knife. Flattening stone for whetstones does its job very well. After having it soaked in water we rub the whetstone against the flattening stone with circular movements until it becomes flat again. The granulation of #220 is suitable for #1000 to #12000 grit whetstones.
