An example of a pencil is what a student uses for answering questions on a test. … Something shaped or used like a pencil, especially a narrow medicated or cosmetic stick.
What type of material is pencil?
Graphite
Graphite is used to make the writing cores of pencils. Wood (Softwood) Softwoods are coniferous trees, such as pines or spruces. Cedar wood is most commonly used in pencil production. The wood encases the graphite, making it easier for the writer to hold.
