Scissors are hand-operated cutting instruments made of regular steel, stainless steel, or more exotic materials in which a handle is fitted to its metal blades. Homes usually keep at least a pair of scissors for household use. Doctors use scissors to cut gauzes. Children use scissors with dull blades to cut papers. Dressmakers use sharper scissors to cut fabric. There are also times that the user got blisters on thumbs and fingers after doing an arts and craft project. Even though scissors have different users, they possess common parts that enable them to function properly.
The most important part of a pair of scissors is the two blades that usually measure less than 6 in (15 cm) long.
Bigger scissors have longer blades use to cut metal sheets for example. It is the cutting part of the scissors. Blades are sharp just like a knife. The two blades are asymmetric because they are made to overlap each other. These blades are attach to a handle.
Handle is the second part of a pair of scissors. It is made of plastic or steel. Generally, it has two oval holes of the same size. Some have one small handle with a hole that fits the thumb and one large handle with a hole that will fit two or more fingers.
The shape of the handle has to follow the shape of the hand and must be able to smoothly transfer the strength of the hand to the cutting edge. The third and smallest part of scissors that looks like a spiral staircase is the fulcrum in a form of screw or pin.
It is made of stainless steel, magnetic or nonmagnetic. It appears shiny. It holds the blades together allowing them to rotate. In conclusion, these parts form together one common object which simplifies household chores, surgery, embroidery, and etcetera.
