Step-by-step guide

1. Select the correct side: If the sharpener has different-sized holes, choose the one that best fits your pencil's diameter.
2. Insert the pencil: Place the pencil into the hole of the sharpener.
3. Twist to sharpen: Turn the pencil clockwise to sharpen it, just like a regular pencil.
4. Check the point: Stop when the pencil reaches your desired sharpness. For soft pencils, be careful not to over-sharpen.
5. Clean as needed: If your sharpener has a collection tray, pull it out to empty the shavings. For better maintenance, clean the blades with isopropyl alcohol and a cotton swab to avoid rust.
6. Sharpen plastic pencils correctly: Plastic pencils can be sharpened using a good cosmetic sharpener, which will sharpen the tip to a precise point.
