Fly fishing is a very flexible and free fishing method. It uses false bait to imitate winged insects such as mosquitoes, dragonflies and flies to attract the attention of fish, so that they can attack the false bait actively and take the bait. The fly fishing method has high requirements for the control ability of fishermen, because the false bait used for fishing is very light and the weight is equivalent to zero, so the throwing should be controlled according to the shape and specific weight of the line.

Fly fishing is a popular stream fishing method in Europe and America, mainly for catching fierce predatory fish. With the progress of society and the improvement of people’s living standards, some people have begun to set foot in fly fishing. Fly fishing is a fishing method often used by senior fishermen. The most attractive thing about fly fishing is the action of the fishing line flying in the air when throwing, as if you can catch fish without thinking.

Chain mail is a kind of metal armor used in ancient wars. In the 5th century B.C. or earlier, it was probably the skites in the north of the Black Sea who first invented chain mail. The early chain mail was inferior to later generations in both material and performance.

The manufacturing method of chain mail is that the iron ring is “linked together”, and its protection ability is related to “the strength of the ring (the strength of the ring itself and the seal)”, “the size of the ring” and “the density of the ring preparation”. The denser the preparation, the better the protection ability. It can prevent cutting and stab, but it is very heavy, requires a lot of materials and takes a very long preparation time; The sparse preparation is not so heavy. It can prevent cutting, but the anti stab effect is poor.

Generally speaking, the bottom of chain mail needs to wear lining Jacket and leather armor. Therefore, it still has a certain protective effect on 1-2cm puncture damage. However, for slender high piercing weapons, the protection ability of chain mail is still poor. After the slender blade passes through the lock ring, it will stab into the body.
