In the long history of stationery, pencil sharpeners have played an important role. Traditional pencil sharpeners, usually made of metal or plastic, are designed with a simple and clear function - to sharpen pencils. These traditional sharpeners usually have a rotating blade and a clip to hold the pencil. Users insert the pencil into the clip and rotate the blade to sharpen the pencil. However, these traditional sharpeners have certain limitations in convenience and efficiency. With the development of technology and people's increasing demand for stationery convenience and comfort, modern pencil sharpeners have undergone significant innovation and improvement. Firstly, automation design: modern pencil sharpeners mostly adopt automatic pencil sharpening design driven by electric power, which reduces manual operation steps and greatly improves the efficiency of pencil sharpening. This automatic design is more easily accepted by the public, especially in the children's stationery market. Secondly, comfort: modern pencil sharpeners focus on user experience and adopt more comfortable materials and designs. For example, some pencil sharpeners adopt anti-slip handle design, so that children will not feel tired or uncomfortable when sharpening pencils. Thirdly, safety features: in order to avoid children from getting injured during use, modern pencil sharpeners are usually designed with safety switches and protective devices. When not in use, they can be turned off to ensure the safety of children. Fourthly, durability and versatility: modern pencil sharpeners are made of more durable materials, and many of them have more functions, such as pencil storage slots and erasers. From the traditional to the modern evolution of pencil sharpeners is a perfect combination of technology and humanization. Although the traditional ones are functionally simple, their existence laid the foundation for subsequent evolution. Modern pencil sharpeners integrate convenience, comfort, and safety into product design. From manual-operated simple tools to electric-driven automated equipment, this process fully reflects the power of technology and people's pursuit of a higher quality of life. Overall, with the progress of technology and changes in people's needs, the evolution and progress of pencil sharpeners, as a stationery tool, have been significant. From simple, rough traditional products to automated and humanized
