Query: Panasonic KP4A-Bk Kp-4a battery pencil sharpener, black.

This Panasonic battery pencil sharpener is by far one of the most useful and well operating sharpener I have ever used. It sharpens pencils in a fashion as to make the tip of the pencil as sharp as one needs. The pencil sharpener its self is a fine working battery operated pencil sharpener. I highly recommend the Panasonic KP4A-BK Kp-4a battery pencil sharpener for those looking for a good quality sharpener. Thanks!
