Which tool is designed to remove the outer skin of fruits and vegetables?

The tool that is specifically designed to remove the outer skin of fruits and vegetables is the peeler. A peeler typically features a sharp, thin blade that easily glides along the surface of produce, efficiently removing just the outer layer without taking away too much of the fruit or vegetable underneath. This is particularly useful for items like potatoes, carrots, and apples, where the skin can be tough and may not be desirable to eat.

A grater is used for shredding or grating foods like cheese or vegetables; it doesn't have the design or purpose for peeling. A turner, often referred to as a spatula, is meant for flipping or lifting food rather than peeling it. Lastly, a bread knife is specifically designed for slicing bread and has serrated edges that are not suited for peeling. Therefore, the peeler is the appropriate tool for this task.
