A graphite pencil is a type of writing and drawing tool that uses a core made of graphite, a soft, shiny black material, encased in wood or a similar material. The graphite core leaves a mark on paper when pressure is applied, and the darkness of the mark depends on the softness or hardness of the graphite. Graphite pencils come in a range of grades, from hard (H) to soft (B), with harder pencils producing lighter marks and softer pencils creating darker, richer marks. These pencils are commonly used for writing, sketching, and shading in art and technical drawing.
