Having a good knife set is important whether you're a home cook or a superstar chef. 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 small fruits and coring veggies, and a chef's knife which will most likely get the most use.
Choose a quality set with handles that fit comfortably in your hand. Hand wash them in warm soapy water, dry, store, and your knives will last you a very long time.
