From Classroom Friendly Office Supplies. This is my new favorite sharpener. Auto feed, auto stop, and easy to clean and service. Removing pencil tips that my kids snap off inside is simple and unfussy. The feed mechanism clamps to the pencil and leaves some small tooth marks. If you demand a pristine, unmarred pencil, be warned.
