text: where did the #2 pencil come from?  where's #1 and #3?   there's a #1 and a #3, but #2, as the compromise candidate, is by far the most common.  #1 pencils have a harder lead, meaning a lighter color and finer line. also, they don't wear down as quickly. on the other hand #3 have a softer lead, giving a thicker, darker line and quick wear that requires frequent sharpening. there are even some numbers beyond that but you are only likely to find them in specialty stores, such as art supply.
