A pencil sharpener is a tool used to sharpen the writing point of a pencil. It typically consists of a rotating blade that shaves away the wood and graphite, creating a fine point for writing or drawing. Pencil sharpeners come in various types, including manual and electric versions, and can be found in homes, schools, and offices. Manual pencil sharpeners are often small and portable, while electric sharpeners are larger and can sharpen multiple pencils quickly. Some sharpeners also have features like a built-in container for shavings. Both types are essential for maintaining the functionality of pencils, which are commonly used for writing and art.
