The fastest electric pencil sharpener from X-ACTO, the Mighty Pro sharpens woodcase pencils to a precise tip in no time. Break-resistant sharpening action ensures frustration-free operation. SmartStop prevents over-sharpening by automatically shutting off the motor when the pencil reaches ideal sharpness; and just to make sure, a bold LED lets you know when your pencil is ready to write. An auto-adjust dial seamlessly accommodates nearly any pencil size, while a slip-resistant bottom keeps the sharpener steady. SafeStart electric motor locks the blades in place when the extra-large, easy-to-empty shavings bin is removed. Compatible with colored pencils. Stay sharp with X-ACTO!
