Flattening Stone - Pink

This Japanese Flattening Stone is useful to flatten your sharpening stones. When sharpening knives with a Japanese sharpening stone, it happens that the latter one gets uneven (more used in its center). This phenomenon is sometimes not even seen to the naked eye. The Flattening Stone allows to flatten the surface of you sharpening stones by simply rubbing the two stones against each other (after humidifying them).
