The arrow (the head of the bow and arrow) is a complete set of details.

An arrow is the head of a bow and arrow. Also known as samarium. Arrow has a long history. Humans have used them for at least tens of thousands of years. In ancient times, people made arrows from animal bones and stones. Later, people invented smelting technology, that is, using bronze to make arrows. Then the iron appeared, and the iron sword head and steel arrow appeared. The arrows in modern competitive archery are all target arrows, generally made of relatively soft alloy, which has poor penetration, so it is relatively safe.

Later, in the long history of human war, all kinds of arrows emerged one after another, such as armor-piercing arrows, loud arrows that can transmit information and so on. The target arrows used in modern archery are generally large obtuse arrows or parabolic arrows. This kind of arrow has small air resistance, but poor penetration, thus ensuring the stability and safety of the arrow flight path during archery.
