General information on Faber-Castell erasers and correct use
History of the eraser
When erasing large areas of graphite, particularly with writing or stroke areas running over several lines, the eraser can often start to 'smudge'. This is because the user tries to erase too quickly and the parts of the eraser have to absorb too much graphite. The eraser can only carry out its task if the movements create a balanced ratio between graphite-free areas and areas containing graphite. The eraser can not become "overloaded"! Erasing parallel to the stroke: Area becomes dirty, erasing is slowed down unnecessarily! Erasing at an angle to the stroke: Erasing the area bit by bit clears the area quickly and effectively!
