Japanese natural whetstones are the final destination for those seeking the best result of sharpening. At Kaz’s knife and Kitchenware, we have a variety of natural stones, most of which are Kyoto’s Shohonyama Awasedo, known as the highest-grade finishing stones. Many of the sites for natural whetstones have been closed, so natural whetstones available in today’s market are limited in number, and the prices are expected to rise due to its scarcity value.
The natural whetstones suited for finishing purposes are mainly siliceous slate and siliceous shale. These are further narrowed down to the ones that meet several requirements such as hardness, evenness of abrasive and absorption of water. Geographically, it is proven that Kyoto and its surrounding have the ideal stratum for natural whetstones, where layers of clay and radiolarian have slowly accumulated on the ocean floor in the equatorial regions at a rate of 1mm per a thousand years since the ancient Permian period (about 250 million years ago). Then, it traveled to the current location in Japan through crustal movement on the ocean plates.
Popularity of Jnat has grown because of the beautiful finishing results on the blade surface. It creates the distinct contrast between the edge line and cladding steel as well as natural luster that evenly appears throughout. Exceptional sharpness is also the point why users prefer Jnat. Furthermore, its delicate abrasive performance prevents excessive grinding on the steel, which often leads to rust developed on scratches. Overall, Jnat enables more precise and even-toned sharpening.
