A mechanical pencil or clutch pencil is a pencil with a replaceable and mechanically extendable solid pigment core called a "lead" / ˈ l ɛ d /. 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 pencil lead draws the circle on a particular paper or material. Alternatively, an ink nib or attachment with a technical pen may be used. The better quality compass, made of metal, has its piece of pencil lead specially sharpened to a "chisel edge" shape, rather than to a point.
Sandwich-paper-like, thin translucent sheet of paper. Manufactured in different strengths, the surface may be slightly polished. This paper also wrinkles upon wetting. Suitable for pencil and felt tipped pens, and with limitations for technical pens. An eraser can be used for pencil lines. Ink is difficult to erase without damage.
Mechanical pencils use mechanical methods to push lead through a hole at the end. These can be divided into two groups: with propelling pencils an internal mechanism is employed to push the lead out from an internal compartment, while clutch pencils merely hold the lead in place (the lead is extended by releasing it and allowing some external ...
Pencils are commonly used at polling stations instead of pens. This is because ink might run on to different sections of the ballot and obscure the voter’s choice. The Facts
The graphite in mechanical pencils is typically much narrower than in wooden pencils, frequently in sub-millimeter diameters. This makes them particularly useful for fine diagrams or small handwriting, although different sizes of refill leads cannot be interchanged in the same pencil unless it has been specially designed for that purpose.
Leonardo da Vinci's Vitruvian Man (c. 1485) Accademia, Venice. Drawing is a visual art that uses an instrument to mark paper or another two-dimensional surface. The instruments used to make a drawing are pencils, crayons, pens with inks, brushes with paints, or combinations of these, and in more modern times, computer styluses with graphics tablets or gamepads in VR drawing software.
