The fine cold weapon among Japanese swords-Tachi
Tachi, a scimitar with a large curvature, with a blade length of more than 3 feet (1m) and less than 5 feet (about 1.5m). Among them, those below 3 feet are called Kodachi, and those above 5 feet are called Odachi (or Nodachi). It is equivalent to the unit of length in Japan, and one foot is about 29 centimeters, which is similar to that of the Northern and Southern Dynasties in China.
Tachi is slightly different from the swords of the same category. One of the differences lies in the scabbard. There are two metal rings on the Tachi scabbard (called "pure gold objects": one near the mouth of the sheath is called "one foot", the other is called "Two feet") woven with ribbons interspersed with each other to make it easy to carry. A small piece of metal (known as the "leather gold object") is connected between the ribbon and the pure gold object. The head of the scabbard is wrapped in metal (called "stone studs"). When drawing the sword, the metal strip (called "mouth gold") at the mouth of the scabbard must be pressed down.
The late Heian period in Japan is called the Tachi era, especially during the "first nine-year battle" and the "second three-year battle" where the samurai power was the most active. For example, Hoki and Bizen countries that produce high-quality iron ore, as well as Yamashiro and Yamato, which are the political and cultural centers, have different styles of swordsmanship. At this time, Japanese swords are mainly used for immediate decisive battles. For the sword.
At the end of the Kamakura period, the two Yuan army invasions and the collapse of the original political system brought great social unrest, which made the knife industry flourish. The Japanese sword of this period is more bold than the mid-Kamakura style. Inherited and carried forward the characteristics of wide sword width and small changes in sword body width, and the cutting is longer. Short swords, swords, and Tachi all have the same characteristics that appear longer than other periods.
During the Northern and Southern Dynasties, a large number of large swords called Odachi and Nodachi appeared differently from the past.
In Japanese swordsmanship, when holding Tachi, there should be no gaps in the palm. The ring finger and little finger grip the hilt tightly, the thumb and index finger lightly pinch, while the middle finger rests on the handle smoothly. Once the sword is out, the only idea is how to knock down the enemy. When a sword is slashed at the opponent, the grip of the sword should be kept unchanged, the hand should not be shaken, and there should be no hesitation. When you attack, block or lower the opponent's sword, you should only slightly change the grip of your thumb and index finger; however, no matter what the situation, the purpose of holding the sword is to knock down the opponent, which cannot be changed.
The way of holding a sword should be the same when trying to hold a sword or in a real fight. At any time, you should hold the sword with the mentality of preparing to knock down your opponent. Generally, the movement of the sword and the way of holding the knife should not be fixed. Fixation means a dead end, and flexibility is the living hand. This point needs to be understood.
Knowing the way of Tachi means that you can control the sword in your hand as you like. In this way, even if you hold Tachi lightly with two fingers, you can swing it easily and flexibly. Swiping Tachi quickly with the Japanese sword technique will inevitably cause difficulty in swinging the sword. It is not the correct human sword technique. If you want to control the sword in your hand flexibly, you must swipe it calmly and gently. When you use the sword to cut down, you should lift it up by the most convenient method, first move it to the side, and then take it back. The correct way to use a human sword is to stretch the elbow as much as possible when swinging, and then make a strong blow.
