As pencil is slippery in touch and the graphite is also slippery in touch. Also pencil is black in color as graphite is. People believe that mankind in stone age used a graphite stone to write on mud so scientist even tried to do same so pencils were created.

Graphite is very soft to easy sharp and very easy write on paper and its smoothly removable. Graphite is a non metal.
