Introduction

Scissors are tools made out of various materials that are created to slice through paper, and occasionally other objects. Scissors blades can take on various shapes to transfer curves and zigzags to paper, but they are typically straight to ensure a smooth cut. Scissors can be various sizes as well, but most are between 15 and 20 centimeters. Furthermore, most scissors weigh a few ounces, but this depends on their size; larger scissors will weigh more (Answers). Scissors are made up of a base that is meant to be gripped by the user and a metal or plastic blade that can be used to slice paper.

Scissor Base

 The scissor base is designed to be held. It is often made of plastic or rubber so that it is comfortable to the user. However, it could also be made of metal, like the rest of the scissor. The base is connected to the blade, and the user can open and close the scissor by moving the two circles of the base outwards and inwards, respectively.

Blade

The blade is what physically cuts the paper or object that will be sliced. The blade is manipulated by the scissor base and is very sharp. Depending on the scissor, the blades can either be very sharp or very dull. This depends on the material use and the angle of the interior part of the blade. The tip of the blade is often very sharp and can be used to poke holes in paper or other objects as a secondary function. In some cases, blades are stored in a scissor holder for safety purposes, to prevent them from separating when the scissor based is moved. This prevents injury.
