It really depends on how much you cook, or what level of cooking ability you are at. I, for example, am an amateur chef trying to explore the world of cooking but am in no means a professional. This is why I prefer knives that are just the right sharpness. If you are a professional, I’m sure I don’t even have to say that sharp knives are needed for your more precise cutting. However, sharp knives are important for any cooking ability level out there, as dull knives tend to be more dangerous than sharp ones.
