Early erasers were mainly made of rubber, which was widely used in writing tools due to its elasticity and easy-to-wipe characteristics. Early erasers were simple cylindrical or block-shaped, often handmade, with a rough surface and difficult to use.
Development of Modern Erasers: With the progress of technology and people's pursuit of quality of life, erasers have gradually developed from simple tools to high-tech products. Nowadays, erasers have made great improvements in materials, shapes, and functions. In terms of materials, modern erasers are mostly made of synthetic rubber or advanced plastic materials, which not only have excellent wiping performance but also have good durability and environmental protection. In terms of shape, modern erasers have more diverse shapes and designs, such as comfortable grip designs, flexible soft erasers, etc. These designs make the eraser more comfortable and convenient to use. In terms of function, modern erasers not only have basic wiping functions but also have some additional functions, such as combined erasers with cleaners or pencil sharpeners. These functions not only meet basic needs but also provide more convenience. Changes in Technology to Erasers: The development of technology has a far-reaching impact on erasers. By integrating advanced manufacturing technology and environmental protection concepts, modern erasers not only improve their performance and comfort but also greatly improve their environmental performance. In addition, the research and application of smart erasers is a typical case of technology changing erasers. These smart erasers not only have basic wiping functions but also have functions such as wireless transmission and automatic error recognition, bringing great convenience to our study and work. Conclusion: From the early simple form to modern high-tech erasers, the evolution of erasers witnesses the pursuit of technological progress and the continuous improvement of quality of life by human beings. With the continuous development of technology, we have reason to believe that future erasers will be more intelligent, environmentally friendly, and multifunctional. Whether in materials, shapes, or functions, they will bring more convenience and fun to our lives.
