There are many different types of zesters on the market, but professional chefs typically use a Y-shaped zester. This type of zester is designed to easily remove the outermost layer of skin from fruits and vegetables, without taking any of the inner flesh with it. Y-shaped zesters usually have two or three different sized grating surfaces, which allows them to be used on a variety of different foods. They also tend to have sharp blades that make quick work of zesting. If you're looking for a quality zester to use at home, we recommend the Oxo Good Grips Y-Peeler. This peeler has a comfortable non-slip grip and includes a built-in potato eye remover. It's also dishwasher safe for easy cleanup.
