I. Diversity of Pencil Sharpeners 1. Manual Pencil Sharpener The manual pencil sharpener is the most common type. Its design is simple and easy to operate, just rotate the blade to easily sharpen a pencil. The advantage of a manual pencil sharpener lies in its portability, which can be used anytime and anywhere, whether in school, office, or home. 2. Electric Pencil Sharpener With the development of technology, electric pencil sharpeners have gradually entered our lives. Compared to manual pencil sharpeners, electric ones are more effortless and can sharpen a pencil faster. Additionally, some high-end electric pencil sharpeners have functions like automatic shutdown and safety protection. 3.

These types of pencil sharpeners not only facilitate the writing process but also improve learning efficiency. II. Usage Skills of Pencil Sharpeners 1. Correct Use of Blades When using a pencil sharpener, ensure that the blade is sharp. A dull blade not only breaks the pencil but may also cause harm to the user. Therefore, it is essential to regularly check and replace the blade. 2. Keep Pencils Dry When sharpening pencils, keep them dry. Wet pencils can rust the blade, affecting its service life. In addition, the shavings produced may be prone to breaking. 3. Safety Precautions When using electric pencil sharpeners, be mindful of safety. Avoid using them when the power cord is damaged or the machine is malfunctioning. Also, do not let children operate electric pencil sharpeners alone to prevent accidents.
