(1) Slingshot was popular in 1970s and 1980s. Slingshot is a cold weapon or a game tool. Slingshot is generally composed of bow frame, rubber band and leather bag. It is usually a "ya" shape made of branches. Rubber bands are tied at both ends of the rubber band, and a piece of skin wrapped in a projectile is tied in the middle of the rubber band.

(2) The strength of the slingshot depends on the tension of the rubber band and the rebound speed of the rubber band. The greater the tension of the rubber band, the heavier the projectile that can be matched, and the faster the rebound speed of the rubber band, which can provide a larger initial velocity for the projectile. The heavier the projectile, the higher the muzzle velocity and the greater the power. According to the launching mechanism, slingshots can be divided into bow slingshots and elastic slingshots. Bow slingshot has the most primitive bow slingshot and crossbow.

(3) Rubber-band slingshots can be divided into traditional slingshots and modern slingshots, and their division principles should be based entirely on the presence or absence of sight and wrist rest labor-saving devices. For example, wooden slingshots and steel wire slingshots without sight belong to traditional slingshots, and the so-called "traditional bow" with sight formed by cutting or casting metal wire should be strictly classified into the category of modern bows.

(4) Because in the whole world, before the development of horizontal grip aiming in China, there was no one or a product to promote the principle of horizontal grip aiming. The earliest horizontal aiming was Wind of the King (and of course the earlier XGD mode), which pioneered the application and promotion of horizontal aiming in slingshot products and was the veritable originator of horizontal aiming slingshot.
