The manufacturing process of the pencil seems simple, but it is actually quite complex. A pencil is mainly composed of a lead and a wooden shaft. The lead's production process involves the processing of wood and the addition of ink. Firstly, selected wood needs to be cut, dried, and polished, and then filled with ink mixture. The wooden shaft also needs to be carefully processed through selection, cutting, and sanding before being combined with the lead to form a complete pencil. III. Multi-functional Uses The uses of the pencil go far beyond writing and drawing. It can also be used for measuring and marking items or even as a drawing tool for engineering drawing and architectural design. Due to its structural characteristics, people can also shave the lead into different thicknesses and shapes to meet different needs. Furthermore, the pencil can also be used for simple physics experiments such as static electricity experiments. IV. Environmental Protection and Sustainability The manufacturing materials of the pencil are mostly wood, which gives it an advantage in environmental protection and sustainability. Compared to many other learning tools, the manufacturing process of the pencil is relatively simple and does not generate a large amount of waste. Additionally, as the pencil is reusable, when its lifespan ends, we can also recycle it to reduce environmental pollution. V. Psychological Effects Apart from
