Scissors were invented by ancient Egyptians around 1500 BC. They were first found in the ruins of ancient Egyptians. These scissors were made of a metal. The modern cross-blade scissors were made by the ancient Romans in 100 AD. Invented, early scissors were used in the manufacture of hair and haircuts.

Scissors have become an indispensable tool for people's daily production and life. They use the principle of leverage, also known as the balance of leverage. In the middle of the knife and the knife, make a shaft eye, then install the spindle, and place the fulcrum between the knife and the knife. This is convenient and effortless to use.
The main component of the scissors is alloy steel. When used, the thumb controls the active blade and the ring finger controls the stationary blade. Scissors are also made up of these two parts. The object is cut by the intersection of two blades, opening and closing.
There are many types of scissors, which are divided into household scissors, flower and wood scissors, steel scissors, medical scissors, tailor scissors, nail scissors, standing scissors, and pen scissors. There are many types and sizes of household scissors, and vanadium is used in processing technology. Vanadium is an important alloying additive in the steel industry. Vanadium improves the strength, toughness, ductility and heat resistance of steel, eliminating the need to sharpen the scissors. There is also child safety for children. The angle of the cutting edge of the child's safety scissors is 60°-90°. It is characterized by a protective body connected to the shear body at the top of the two shear bodies and below the top of the protective body. The built-in tip. It is structurally guaranteed to have good shearing function, easy operation and durability. It is not easy to cut the finger and can not cause substantial damage to the eyes. It can relieve parents' concerns and enable children to get early paper-cut training and improve their intelligence. scissors.
In order to increase the sharpness of the scissors blade, carbon is added to the steel of the medium and high-grade scissors, so the scissors are prone to rust. If the scissors are not used for a long time, there may be rust spots, which may eventually lead to failure to open or close. There are also some oils and chemicals or sweat on the hands of people that can cause the scissors to rust. If the scissors are rusted, you can use aluminum foil, then rub the rusty scissors back and forth, the rust will disappear, and the blade will become sharp.
