Panasonic - Vertical Electric Pencil Sharpener
This is the only auto pencil sharpener I trust for sharpening my Ticonderogas. The vertical design makes sharpening easier and has Auto-Stop so it never over-sharpens your pencils! Don't waste your $$ on cheap imitations (Like XACTO sharpeners) that always break. Trust me, your students will love you for it.
