What does sharpener mean?
A sharpener is a tool that restores a pointed or cutting edge to an object. Its most familiar form is the small device used to sharpen pencils, commonly found in schools, offices, and homes. Sharpener can also refer to specialized equipment for knives, scissors, chisels, and other edged tools, including manual and electric models. The word is straightforward and usually neutral in tone, though "brain sharpener" and similar playful expressions use it metaphorically for an activity that improves mental alertness. In general use, the specific compound often identifies the intended object: a pencil sharpener, knife sharpener, or even a diamond sharpener for certain tools.
