Pencil Drawing

According to their manufacture
• Mechanical pencils
There are also pencils which use mechanical methods to push lead through a hole at the end and are either propelling or clutch type. The erasers (sometimes replaced by a sharpener in larger lead sizes) are also removable (and thus replaceable), and usually cover a place to store replacement leads. Mechanical pencils are popular for their longevity and the fact that they may never need sharpening. Lead types are based on grade and size; with standard sizes being 2.00 mm, 1.40 mm, 1.00 mm, 0.70 mm, 0.50 mm, 0.35 mm, 0.25 mm, 0.18 mm, and 0.13 mm (ISO 9175-1)—the 0.9 mm size is available, but is not considered a standard ISO size.
