Introduction Learning tools have always been important for us to acquire knowledge, learn, and grow since the dawn of human civilization. From the earliest scratching tools to modern electronic devices, the evolution of learning tools has witnessed the progress of human civilization. This article will focus on the evolution of learning tools from pencils to erasers, and how they have influenced our learning and lifestyles. II. The Origin and Evolution of Pencils Pencils are one of the oldest and widely used writing tools. Their origin can be traced back to ancient scratching tools. Early pencils were made of wood and graphite, with simple processing and grinding, gradually developing into the pencils we are familiar with today. With the development of technology, the materials and manufacturing processes of pencils have been continuously improved, such as the addition of various pigments, lubricants, etc. to improve writing performance. III. The Invention and Popularization of Erasers Compared to pencils, the invention of erasers is relatively late. However, its impact on modern learning and office environments is huge. Early erasers were mainly made of rubber, used to erase the traces of pencil writing. With the development of technology, the materials and shapes of erasers have been continuously improved, such as the addition of plastic, metal, and other materials to improve durability and practicality. Nowadays, erasers have become essential learning and office supplies for students and office workers.
