n ancient Rome, scribes wrote on papyrus (an early form of paper) with a thin metal rod called a stylus, which left a light but readable mark. Other early styluses were made of lead. Today we still call the core of a pencil the "lead" even though it is made from nontoxic graphite.

The earliest graphite pencils had no outer surround of wood, the were just graphite rods, and were used even when I was a boy in school, we had slates that we wrote on, then prior to timber they were wrapped in paper so well you would have thought it was wood.
