Natural sharpening stones
Natural sharpening stones, known as JNATs or Tennen Toishi, are quarried from mountains across Japan. These stones are a product of Japan’s unique sedimentary and geological history, which makes them rich in silica and aluminum oxide—key elements that enable effective sharpening of steel. Japan is one of the few places in the world where such a diverse range of these stones can be found.
The availability of these natural stones has played a crucial role in Japan’s history of swordmaking and the production of high-quality tools. Beyond their practical uses, they also hold significant historical and cultural value. The world of natural sharpening stones is as complex as it is fascinating.
Advantages of Tennen Toishi
Tennen Toishi stones offer performance that’s unmatched by most man-made sharpening stones. They are known for their longevity, superior edge quality, and the ability to produce exceptional polishes. These stones typically provide better cutting performance and long lasting edges.
