The blacker the stone, the harder and finer the stone tends to be.

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 faced by 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.
