Some people prefer to do things by hand. Most manual pencil sharpeners work by turning a crank, which rotates blades around inserted pencil heads. Manual pencil sharpeners come with various mounting options, allowing permanent installation or temporary installation on a desk top or other smooth surface.
Choose a handheld pencil sharpener for individual use and utilize a selector dial to work with many different types of pencils, including thicker children's pencils. When cleanliness is a concern, make sure pencil sharpeners have built-in antimicrobial protection to thwart germs and bacteria.
