HB Graphite Grading Scale — Pencil Fight

Numerical Graphite Scale. The first graphite grading scale is a numeric scale. Using this scale, the hardness of the core is often marked on the pencil — look for a number (such as "2" "2-1/2" or "3"). The higher the number the harder the writing core and the lighter the mark left on the paper. As the pencil core becomes softer ...
