The body of a sharpener is typically made from plastic, wood or metal.
Plastic
The plastic used for the body of sharpeners is acrylonitrile butadiene styrene (or ABS for short). It is commonly used in many manufacturing processes because it is lightweight, tough and impact resistant. Children’s building blocks are commonly made from ABS.
Blade
The blade of a pencil sharpener is usually made of stainless steel.
Stainless steel
Stainless steel is an alloy of steel and chromium. This composition makes it resistant to rust, stain and corrosion.
