a. Manual Sharpener

Manual sharpener is one of the most common types of sharpeners. It's easy to use - simply insert the pencil into the opening of the sharpener and rotate it to sharpen the pencil. The advantage of manual sharpeners is that they are cheap and easy to carry, and they are very friendly for beginners. However, it should be noted that the sharpening effect of a manual sharpener may not be as good as an electric one.

b. Electric Sharpener Electric sharpener is a type of sharpener that has become increasingly popular in recent years. It uses electricity to quickly and effectively sharpen pencils, with a better result than manual sharpeners. Electric sharpeners are very convenient to use, especially for students and workers who need to frequently sharpen pencils. However, it should be noted that electric sharpeners are relatively expensive and require regular replacement of blades or refills. c. Electric Smart Sharpener The electric smart sharpener is an upgraded version of the electric sharpener. It not only has the function of quickly sharpening pencils, but also has intelligent recognition and automatic shutdown functions. This type of sharpener can automatically adjust the degree of sharpening according to the material and hardness of the pencil, avoiding waste and damage to the pencil. Additionally, electric smart sharpeners have a anti-pinch design for safer use. However, due to its complex functions, it is relatively expensive.
