--- How to Use a Pencil Sharpener: Bring New Life to Your Pencils Preparation: Firstly, you need a pencil sharpener. There are many types of pencil sharpeners, both manual and electric ones. Regardless of the type, their basic structures are similar, with parts that fix and reduce the pencil. Make sure your pencil sharpener is clean and in good working order. Procedure: 1. Adjust the pencil: Insert the pencil into the entrance of the pencil sharpener, ensuring that the wooden part of the pencil is completely within the cutting range of the sharpener. 2. Start the pencil sharpener: For a manual pencil sharpener, you need to hold the handle and rotate it; for an electric pencil sharpener, simply press the switch or button to activate it. 3. Cut the pencil: Allow the pencil to rotate or move within the sharpener, cutting off the unwanted parts. Be careful not to cut too much, as this may shorten the pencil to a point where it is unusable. 4. Stop and remove the pencil: When the pencil has been cut to the desired length, stop rotating or moving the pencil and gently remove it from the sharpener. Safety Tips: 1. Keep your hands dry and clean while using the pencil sharpener to prevent slipping or accidental injury. 2. Do not place other items near the pencil sharpener to prevent scattered wood chips from causing contamination. 3. Clean the pencil sharpener after use to keep it tidy and in good working order. 4. If you are using an electric pencil sharpener, replace the batteries when they are low on power. Conclusion: By following these steps, you have learned how to use a pencil sharpener to bring new life to your pencils. This is a simple but useful skill that you can apply in your daily studies and work. Remembering to keep tools clean and used correctly can not only improve work efficiency but also extend the lifespan of tools.
