Many large knives will have iron rings on the back of the knife, but not all of them have them, and often the heavier the large knife, the greater the number of iron rings. Therefore, the number of iron rings can basically represent the weight of the large knife, and if you see nine iron rings on the opponent's large knife, you are basically ready to escape.
Some relevant scholars have found that only some masters of the sword can use the large knife with nine rings, and ordinary people cannot use it at all. And these iron rings are actually not without effect, its most important role is that if the large knife is cut in trees and other places can not be pulled out, you can use something to wrap the iron ring to pull out the large knife, which is much more effective than directly drawing the handle.
The knife method of the big knife is generally a big chop, not particularly dexterous, a little attention will be cut into other things can not be pulled out, so the invention of the iron ring. Another function of the iron ring is to increase the power of the large knife, because the iron ring is active, when swinging out, the iron ring will move to produce inertia, so that the large knife swing more smoothly, the greater the force, so the more rings, the greater the power.
Throughout the ages, the types of large knives have also evolved, with a wide variety of types, including long-handled knives and short-handled knives, long-handled knives are generally used when riding horses, and infantry battles are more short-handled knives. According to the characteristics of different large knives, the ancients created many knife methods, many of which have been handed down to the present day and have become excellent cultural heritage.
