Introduction of ancient Japanese weapons

There were five kinds of weapons in ancient Japan: knives, guns, razors, bows and arrows, and iron cannons. The most commonly used weapon is a knife, which represents the spirit of a samurai and is also a symbol of his status. Usually he wears two knives, a long knife, a short rib gap, and a racket knife with a length between the two and a shape closer to the knife. The blade of Taidao is long and narrow, and the blade is curved, generally above 1 10cm, which is mostly used for immediate use. The length of the knife is about 100cm, and the blade is straight, so it can be used in combat. A short knife with a rib difference of less than 60 cm, used for indoor fighting. The sword is about 30 cm, without a shovel, for women's self-defense. Both the sword and intercostal space are used for abdominal incision.
