Product information
On the southern Japanese main island of Kyushu, there are still two mining areas for natural sharpening stones. One is located near the volcano Unzen-dake in Nagasaki Prefecture. The other area – not far from it, only separated by the Hayasakiseto Strait – is located on the island of Shimoshima near the city of Amakusa in Kumamoto Prefecture. These sharpening stones are each named after their origin.
These natural sharpening stones cannot be precisely defined by their grain, so we provide a range that should only be understood as an approximation. All stones are neatly cut into rectangles. The depicted stone may vary in color and structure from the delivered stone, depending on which layer it comes from.
Overall, these stones are affordable and therefore a good entry into sharpening with natural stones. These stones are also relatively tolerant regarding the type of steel – both carbon steel and stainless steel blades can be sharpened. The stones on this page all have a medium grain. For honing, a stone with a grain size of 3000 or higher should follow.
Edge or corner breakages in the range of several mm are normal for these natural stones and should be tolerated; the suitability for sharpening is not impaired. The color designation „white” or „red” is traditionally grown and is actually a trade name and therefore only partially related to the actual color.
Texture and color vary greatly in some cases (see second image).
