The word graphite is from the Greek language which translates as 'to write'. So the most common uses of graphite is in making the lead in pencils. "Lead" pencil cores are made of a mixture of clay and graphite, which is in an amorphous form. Loosely cleaved graphite flakes mark the paper, and the clay acts as a binding material.
The graphite is exfoliated by mechanical, chemical or electrochemical methods to produce graphene flakes (Kauling et al. 2018).
