Re: Colored pencil sharpener...need updates!
Be sure to sharpen a graphite pencil every half hour or so. It also helps to clean the blades with an old toothbrush after about 3 days (72 hours) of use. Janie Gildow demonstrates this procedure in one of her YouTube videos. As you brush the blade and gears, do make sure the helix blade rotates by GENTLY pushing on the unit.
I have several Panasonics, both battery operated and electric types, and love the long, sharp points they give. They're well worth the effort to keep colored pencil core shavings cleaned out of the blades and gear mechanisms.
Comments and critiques are welcomed.
