You do not need the whole range of graphite pencils, from 9H to 9B! When I work with graphite, I usually have an HB, 2B, and a 4B. On the occasion that my drawing requires a very dark value, I may also use a 6B. If you are just beginning drawing, you may want to add a 2H for the lightest values in your drawing.
