Pencil
Description
A pencil is a writing or drawing device consisting of a slippery, thin stick of pigment (usually graphite, but can also be colored pigment or charcoal) and clay, usually encased in a thin wood cylinder, although plastic sheaths are also used. Many pencils across the world are graded on the European system using a continuum from "H" (for hardness) to "B" (for blackness), as well as "F" (for fine point). The standard writing pencil is graded HB.
