When we think of a pencil, we usually imagine a long, slender, wooden stick with a graphite core. However, there is one more vital component in a pencil that is often overlooked - the metal part.
What is the Metal Part of a Pencil?
The metal part of a pencil, also known as a ferrule, is a small metal band that holds the eraser in place. It is usually made of aluminum, brass, or nickel-plated brass. The ferrule is crimped onto the end of the pencil, securing the eraser and preventing it from falling off.
History of the Ferrule
The ferrule was not always a part of the pencil. In fact, the first pencils did not have erasers or ferrules. Instead, they were wrapped in string or leather to prevent the graphite from breaking or rubbing off. It was not until the mid-19th century that the ferrule was introduced to hold the eraser in place.
The first ferrules were made of brass and had a flat top. However, this design had a flaw - the eraser would often slide out of the ferrule. To solve this problem, a new design was introduced in the early 20th century. This design had a tapered shape, which held the eraser more securely in place.
How is the Ferrule Made?
The ferrule is made using a process called crimping. First, a thin strip of metal is cut and shaped into a circular band. The eraser is then inserted into the ferrule, and the ferrule is placed onto the end of the pencil. Finally, the ferrule is crimped onto the pencil using a special tool that presses the metal band tightly around the pencil.
The Importance of the Ferrule
Although the ferrule may seem like a small and insignificant part of the pencil, it plays a crucial role in making the pencil functional. Without the ferrule, the eraser would fall off, and the pencil would be rendered useless. Moreover, the ferrule adds a touch of elegance and sophistication to the pencil.
Conclusion
The metal part of a pencil, or the ferrule, is a small but essential component that holds the eraser in place. It has a rich history and has undergone several design changes over the years. The ferrule is made using a process called crimping, and it plays a vital role in making the pencil functional. So, the next time you use a pencil, take a moment to appreciate the small but significant role played by the metal part.
