Electric pencil sharpener features patented, X-ACTO fly-away cutter system that stops sharpening when pencil is sharp. Multiple-size pencil selector offers positions for standard, beginner and triangular pencils. Shavings fall into a large transparent receptacle (535 cc) so you don't have to empty as often. SafeStart receptacle interlock switch shuts off the motor when receptacle cover is removed for your safety. SharpX Performance Electric Pencil Sharpener is also equipped with a shavings-full LED indicator, hardened-steel helical cutter and noise-isolating, suction cup feet.
