Powerful, battery-powered pencil sharpener offers a space-saving design and is ready wherever you are. Cutter life is four times longer than standard cutters with HHC technology. The powerful motor operates stall-free under normal use. Tip Saver Technology extends pencil life by preventing oversharpening. Safety switch prevents operation when the easy-to-clean, translucent shavings tray is removed. Sharpener runs on four AA batteries (sold separately) for wireless operation or convenient portability.
