Four Common Knives for Cold Weapons in China

China, a cold weapon, often uses four big knives. In order to cut something, it is also a blow. "Its weapons are famous for their boldness and ferocity, ranking first among the eighteen weapons.

The word "tangdao" is the general name of four knife systems in the Sui and Tang Dynasties in China, not a certain knife. It is not just this period of the Tang Dynasty. The appearance and manufacturing technology of tangdao have a great influence on swords in East Asia, especially in mountain cities.

For the army, tangdao's combat knives play the most important role in fighting. Their production technology is rigorous, and at the same time, they also take into account another purpose in fighting, that is, armor-piercing and durability. Armor-piercing requires hardness and narrow cutting edge, so durability requires toughness, so tangdao has adopted the most advanced steel-clad technology. It is made of stainless steel with wrought iron in the middle, and some cutting edges adopt local quenching technology, that is, the cutting edge is hard and can split armor, and the blade body is tough and durable. This is also the biggest difference from Japanese Dao.

Then a simple way to distinguish a straight knife like tangdao is: the angle of the tip is tangdao. A Japanese straight knife with a blood groove at the tip of a semicircle and a blade area of more than half to one third.

The waist knife of the ancients is the shame of Jingkang. More than 30 years later, in the first year of Dadao (A.D. 1 165), the military equipment supervisor of the Southern Song Dynasty began to make a new kind of knife weapon, which was named "Yanling Knife" because it looked like the feather of a wild goose.

By the end of the Yuan Dynasty, "waist knife" began to be the general name of all knives and weapons hung around the waist by hanging beams and ropes. In the hundreds of years after the establishment of the Ming Dynasty, it began to appear frequently in submissions and folk romance novels.

During the Jiajing period of the Ming Dynasty, civil strife occurred in Annan (now Vietnam). In the Ming Dynasty, Zhu Houzong sent Mao Bowen, the minister of the Ministry of War, down to Annan to quell the unrest. When Mao bowen went out to war, the Ming dynasty gave him a poem: "The general marched bravely in the south, his waist crossed the sword of autumn water, the wind blew mountains and rivers, and the lightning flashed high." There is a unicorn in the sky, so how can the ants in the cave escape? When we return safely, we will untie our robes with our husbands. "

Embroidered Spring Knife is a standard weapon worn by the Royal Guards. It is made of high-quality steel. The higher the position, the purer the embroidered spring knife material and the more casting processes. It is said that besides iron, other metals are doped, which makes the blade extremely sharp. Embroidered Spring Knife is longer than a single sword and slightly shorter than a common long sword. It is shaped like a razor with a thick back and a thin blade. However, the whole blade is curved and the handle is quite long, which can be used by both hands, which is not only beneficial to foot fighting, but also suitable for horse fighting. It is enough to cut off the whole horse's head with one knife.

Qi Jiguang, an anti-Japanese national hero in Ming Dynasty, combined Japanese Dao with China Long Dao (such as Yi Dao) and improved it into a more powerful Miao Dao. He also combined China's marksmanship, knife method with Japanese knife method, and created the method of heart-felt knife, which was used to fight the Japanese pirates in coastal areas, so it was also called "anti-Japanese knife method". It is called Miao Dao because its blade is slender and looks like a rice seedling, so it was named Miao Dao in the period.

Miao Dao is extremely lethal on the battlefield, far exceeding Japanese Dao. It is a great shock to China to kill the enemy, to raise the flag and to rely on the knife method. Charge is both a knife and a gun.

Miao Dao has always existed in China. The Han dynasty was a ring-headed straight knife. The Tang Dynasty was the broadsword and the Tang Yi Dao. In the Tang Dynasty, radian gradually appeared. This is already the shape of modern Miao Dao. There are several Tang broadswords copied from Japan or imported from China in the Masakura Museum in Japan, just like Miao Dao.

During the period, the martial artist was Chang 120~ 160 cm, and the long Dao shaped like a rice seedling was named Miao Dao, which was recognized. At the same time, a Miao Dao handed down by martial artists for hundreds of years combined with arm-tong stunts made two Miao Dao. Miao Dao once again flourished in Wulin, which attracted the attention of Japanese kendo. At this point, Japanese kendo invited China Miao Dao masters to fight many times, but Japanese kendo lost more and won less.
