Choose the Right Pencil Sharpener Firstly, you need to choose a pencil sharpener that is suitable for your pencils. Different pencil sharpeners have different sizes and functions, so you need to select the right one based on your needs. At the same time, pay attention to the quality and brand of the pencil sharpener to ensure its service life and sharpening performance. 2. Correctly Place Your Pencils

When using a pencil sharpener, it is necessary to place your pencils correctly. Generally, you need to insert the pencil into the clamping groove or guide rail of the sharpener and ensure that it is parallel to the guide rail. This can ensure that the pencil does not deviate from the direction or break during sharpening.

3. Control the Number of Sharpening Times and Force When using a pencil sharpener to sharpen your pencils, you need to control the number of sharpening times and force. If you sharpen too short or too fast, it may cause the pencil to break easily; if you sharpen too slowly or too little, it may affect the writing effect. Therefore, you need to adjust the number of sharpening times and force appropriately based on the material and thickness of the pencil. 4. Keep Your Pencil Sharpener Clean After each use of the pencil sharpener, remember to clean it. Residual pencil shavings may affect its performance in the next use. You can use a small brush or blowing to clean the residuals inside the pencil sharpener. At the same time, be sure to regularly clean the shell and clamping grooves of the pencil sharpener.
