A mechanical pencil or clutch pencil is a pencil with a replaceable and mechanically extendable solid pigment core called a "lead" / ˈlɛd /. The lead, often made of graphite, is not bonded to the outer casing, and the user can mechanically extend it as its point is worn away from use. The vast majority of mechanical pencils have erasers.
