ABSTRACT:
An automatic pencil with a lead-sharpening device, has a pencil lead of a diameter of 2 mm inserted into the pipe sleeve of the pencil case in which a lead-sharpening knife holder is attached. Whenever the lead becomes dull, the user presses and turns the cap on the top of the pencil and then sharpens the lead by the knife holder to make the lead ready for continued use, and the user can retract the lead back to the pencil case if the pencil is not used to prevent the lead from being broken or damaged.
