Safety is also an important factor to consider when selecting a pencil sharpener. Ensure that the blade part of the pencil sharpener has a protective cover to prevent accidental injuries. In addition, the handle design should be comfortable and non-slip, easy to hold. II. Usage of Pencil Sharpener 1. Place the Pencil Correctly When using a pencil sharpener, the pencil should be placed in the correct position. Generally speaking, the pencil should be placed in the center of the blade for a uniform tip. 2. Apply Moderate Force When sharpening a pencil, moderate force should be applied. Excessive force may result in a too-thin tip or damage to the pencil, while too little force may not produce an ideal tip. Therefore, mastering the right amount of force is the key to using a pencil sharpener. 3. Regular Cleaning and Maintenance To maintain the good performance and extend the service life of the pencil sharpener, regular cleaning and maintenance are necessary. During use, timely clean up the shavings to avoid blocking the blade. In addition, regularly checking whether the blade needs to be replaced or sharpened is also essential.
