5. Price: Consider your budget and compare the prices of different brands and models of pencil sharpeners. Remember that although a higher-priced product may have better quality and functions, it may not be suitable for everyone. II. Using a Multi-Function Pencil Sharpener 1. Safe Use: When using a multi-function pencil sharpener, follow the manufacturer's guidelines and safety tips. Be sure not to let children touch or use it without adult supervision. 2. Preparing the Pencil: Insert the pencil that needs to be sharpened into the appropriate position of the sharpener. Ensure that the pencil is inserted correctly to avoid damaging the sharpener or causing injury. 3. Adjusting the Thickness: If the sharpener has a function to adjust the thickness of the pencil tip, you can adjust it according to your needs. Generally, a thicker pencil tip is suitable for drawing or writing, while a thinner pencil tip is suitable for fine work. 4. Start Sharpening: Press the switch or button of the sharpener (if any) and start rotating the pencil. Be careful not to apply too much force to avoid damaging the pencil or sharpener. 5. Cleaning and Maintenance: After using the multi-function pencil sharpener, clean the internal pencil shavings and residues promptly. Regularly maintain the sharpener to extend its service life.
