70 x 125 x 35 mm 647g Soft Contains a new mineral discovered in the 80's. Please inquire for details when you own it. Hardness drops significantly due to moisture content. Quite close to Toyama. Trachy-modified andesite from Tobe-cho, Iyo-gun, Ehime Prefecture #800~4,000 grade The harder it is, the higher the chance of fineness. The blacker the stone, the harder and finer the stone tends to be. If it is hard, it will lose its self-sharpening ability, so depending on your purpose and level of skill, you should continue sharpening while performing Kyonagakake each time.
Natural whetstones from Iyo Province are said to have already been distributed in the Setouchi Inland Sea during the Kofun period, and are famous as masters of the whetstone industry in one of the oldest and largest igneous rock systems in the world, said to be over 1,500 years old. Our country's precious mineral resources were such that they could completely change the nation and the nation. The unique iron sand metallurgy, which developed due to the lack of iron ore and had a much lower yield, and the fact that it was the last to start because it was located on a remote island in the Far East, were fatal conditions that would have been as bad as losing a limb to create an iron civilization. there were. Looking at our history and tradition, we can confirm that consumables that allow us to process harder and more tenacious iron products as we wish are our country's most famous abrasive resource. Until the 19th century, the performance of natural whetstones dominated the development of ironware. Despite its poor location, it is home to one of the world's oldest and largest wooden buildings. Japanese swords are the result of extraordinary skill in ironware. The world of samurai, who risked their lives on a single swing, lasted for 700 years. Despite being a latecomer to the country, it had already invented the world's best iron products in the Middle Ages, and today it is known as a manufacturing nation. The Iron Age lasted from prehistoric times until the middle of the Heisei era. In other words, the power to draw out iron was itself a working medium that weaved the maturation of not only manufacturing, but also culture and the nation. The precious stone resource, which is irreplaceable and precious, and full of uniqueness and truth, has pushed back against the many layers of adversity that have faced iron. If we estimate Japan's various resources based on the values of the modern era, when oil and nuclear power were of no value, we would say that Japan is a resource-rich nation. The strength gained only through the process of pushing back against lack and inconvenience adds depth to history and tradition, and lights up the soul. Caution
