Pencil sharpener: History, Manual & Specialized

A pencil sharpener (or pencil pointer, or in Ireland parer or topper) is a tool for sharpening a wood-cased pencil's writing point by shaving away its worn surface. Pencil sharpeners may be operated manually or by an electric motor. Many sharpeners have a casing around them to contain the pencil shavings produced during use.
