Japanese swords have long been a symbol of samurai. They are also used in iaido martial arts, whose aim is perfect artistry and spiritual discipline. At every iaido competition, people with exceptional skills can demonstrate the forms of iaido and show their skills. Real swords are used and you can fell tension and focus during performance.

From ancient times, swords were considered sacred objects imbued with spiritual power. The Japanese sword has over 1500 years of history and it is more than just a great weapon. For about 1000 years, aristocrats used swords in Shinto ceremonies and rituals. Ceremonial swords were beautifully decorated and they were used as a show of power and wealth. Even in times of war, swords never became a weapon chosen on the battlefield. Spears and pistols were considered more effective weapons and katana were reduced to an auxiliary role. Instead, they were the most important element of the Samurai costume and the well-made sword was very expensive. Japanese katana are nowadays associated with samurai but there was a time when everyone could have a sword. In the 16th century, Toyotomi Hideyoshi, a Japanese military and political leader, issued an order to confiscate swords. He would not allow anyone outside the samurai class to have katana. This created a clear difference in status between samurai and ordinary people and gave birth to the concept of the sword as the mark of the samurai. When peace spread throughout Japan in the 17th century, samurai remained the only class of people allowed to wear a sword. As it become less common for a sword to be drawn the act of doing so acquired greater significance. Eventually not drawing a sword came to be considered a virtue. In this way, the katana steadily gained a deeper respect as a symbolic object. This state of affairs was broken in the nineteenth century, when the government dissolved the class of warriors and forbade the possession of swords. The era of the sword as a status mark has come to an end. But they still live in martial art and as works of art. Even today, they are adored by many Japanese.

The metal for the Japanese sword is made by using a traditional method called tatara. The iron is heated for three days and three nights, while adjusting the temperature. The product of this heating is called tamahagane. It is thrown into the fire and heated to around 1500 degrees Celsius. Then tamahagane is hammered to modify its shape and thickness. When it is broken up to a thickness of 5 mm, it is placed in water to cool it down. Then it is broken into smaller blocks. Parts that break easily are hard and used on surfaces where sharpness is required. The difficult to break parts are more resistant and used in the core of the sword to provide it with flexibility. Small tamahagane blocks are arranged in an even pile so that heat can penetrate in the same way through each element. Then the metal is covered with ash and topped with water. It cuts off the access of air and allows the heat to penetrate slowly inside. The steel melts and then is hammered again, which strengthens it and improves its quality.

After about 15 cycles of folding, heating and forming the blade, it has a thickness of 15,000 layers. This is what gives the strength and reliability of Japanese swords. Then the steel is extended with a small hammer. This determines the shape and is the process in which the skill of the craftsman is crucial. After forming the shape, a mixture of clay, charcoal and other materials is spread over the blade. The thickness of this layer is increased in some places. The mixture and its thickening influence the heat transfer in the final thermal treatment and determine the characteristic pattern on the blade. The sword is heated to 800 degrees and then submerged in water for cooling. This is the most intense moment for the creator of the sword. A sudden change in temperature naturally underlines the beautiful curvature of the katana. In this short moment the soul enters into blade. Then it is passed to craftsmen who polish the surface in order to finish the creation of the sword. Based on technique, instinct and years of experience, masters in this art still produce the highest quality blades.One of them is Yoshiaki Sugita who constantly invents unique methods to create blades of unusual originality. He is one of the most valued swordsman in Japan. One day he received iron in a very valuable form – these were nails made over 200 years ago. These nails were collected during the repair of the famous temple from over 1200 years – Suo Kokubunji. It is believed that when it comes to materials for sword, the older the metal, the better. Ancient nails were melted to make the raw material. Iron from 200 years ago was something that Sugita had never used before. He could not use the rules of making swords he knew. He had to rely mainly on his instinct. He wanted to recreate Juka-choji – a pattern on the edge of a knife from the Kamakura period, which represents the overlapping petals. However, the method of creating this pattern is shrouded in mystery. Sugita tried to recreate it for almost 30 years. Without success. However, old temple nails could give him a chance to get a petal pattern. It took him half a year and one failure to recreate a blade with Juka-choji pattern. During the offering ceremony, Sugita offered sword to the temple.
