I have several knives that I used for various things however my main go to knifes are two Serrated knives, a cheep one I used for tomatoes and a good one that I use for bread. I also have two chef knifes, one for meat and the other for everything else. Meat requires a really sharp knife so the one I reserve for meat is to ensure it will always be sharp when I need it. This started back when my roommate was still alive and every time I needed to cut meat, the knife was dull. Rather than have an argument, we simply bought another knife.
