The most important ingredient in a pencil is the graphite.
The wood used to manufacture pencils must be able to withstand repeated sharpening and cut easily without splintering. Most pencils are made from cedar (specifically, California cedar).
Most pencil cores are made of graphite .
The most common type of pencil casing is of thin wood, usually hexagonal in section but sometimes cylindrical, permanently bonded to the core. Similar permanent casings may be constructed of other materials such as plastic or paper. To use the pencil, the casing must be carved or peeled off to expose the working end of the core as a sharp point. Mechanical pencils have more elaborate casings which support mobile pieces of pigment core that can be extended or retracted through the casing tip as needed.
