Question: what is the difference in drawing pencils?
Answer: Grades of drawing pencils are organized in a scale based on softness or hardness. An "HB" pencil is found directly in the center of the scale. "H" pencils feature harder graphite. ... Therefore, a "4H" pencil will produce lighter marks than an "2H" pencil while a "4B" pencil will make darker marks than a "2B" pencil.
