Whether you're a home cook or a superstar chef, a good knife set is essential. Chances are you won't use every knife in your set every day, but it's nice to know the option is there.
You'll want a serrated knife for cutting bread, a paring knife for cutting and coring small fruits and vegetables, and a chef's knife for chopping and dicing.
Choose a quality set with handles that fit comfortably in your hand. Your knives will last a long time if you wash them in warm, soapy water and dry them thoroughly before storing them.
