A manual pencil sharpener is a small, hand-operated tool used to sharpen pencils by rotating the pencil against a blade. The user inserts the pencil into the sharpener and turns it, causing the blade to shave off the wood and expose the pencil lead. Manual sharpeners are simple, portable, and do not require electricity, making them ideal for use in schools, offices, or at home. They come in various designs, including compact handheld versions and larger, more sturdy models with a collection container for pencil shavings. Manual pencil sharpeners are widely used due to their reliability and ease of use.
