2. Hold it steadily: When sharpening a pencil, make sure your grip is stable. Excessive shaking may result in unevenly cut pencils. 3. Apply appropriate force: When sharpening, don't apply too much force. Excessive force may cause damage to the blade or break the pencil. Apply an appropriate amount of force so that the blade can easily cut off the outer skin of the pencil. II. Maintenance and Cleaning 1. Regular cleaning: Regular cleaning of the pencil sharpener can keep it in good working condition and extend its service life. After each use, use paper towels or a cloth to wipe the inside and outside of the sharpener to remove pencil shavings and other debris. 2. Blade maintenance: The blade is a critical part of the pencil sharpener, so special attention should be paid to its maintenance. When the blade becomes dull or damaged, it should be replaced with a new one promptly. At the same time, ensure that the new blade is suitable for your pencil sharpener. 3. Avoid damp environments: The pencil sharpener should be stored in a dry environment to avoid dampness. A damp environment may cause rust on the pencil sharpener and affect its service life. 4. Safe storage: When storing the pencil sharpener, ensure it is placed in a safe place to avoid children's access. At the same time, avoid placing the pencil sharpener in direct sunlight or high-temperature places to prevent damage.
