    • PROBLEM TO BE SOLVED: To simply form a flat lead without any trouble by shaving a pencil barrel while a lead is left unsharpened, then placing the unsharpened lead on a receiver provided against a molding tool and pressing the lead with a groove which fits the thickness of the flat lead and the molding tool with a blade part installed on both lateral edges. SOLUTION: When introducing a pencil main body into the supporting cylinder of a pencil sharpener to mold a lead, only a wooden barrel is shaved in a cylindrical form, while a lead is left unsharpened. On the tip side of clampers 8, a groove 6a which fits the thickness of a flat lead to be molded is formed lengthwise, and a molding tool 6 constituted of blades 6b, 6b mounted along both lateral edges of the groove 6a and a receiver 7 which receives the lead and is provided against the groove 6a, are also fitted, in a freely detachable manner, against the tip side of the clampers 8 by an appropriate means. The clampers 8 is of such a structure that a pair of handles are crossed and pivotally supported so that they are openable. After positioning the lead of the pencil main body on the receiver 7, the molding tool 6 is pressed with the groove 6a of the molding tool 6 and the blades 6b, 6b fitted against the former, so that the lead is sharpened into a flat lead.
