I know that, but you can use graphite to create graphene quite easily. Graphene was manufactured initially by a process as simple as using graphite for rubbings and pulling off thin 1-5 atomic layer thick sheets with scotch tape. No loving joke, I actually tried some rough testing of the process when I read about it because other methods of making graphene have been high in cost while producing arguably worse samples due to impurities etc.
