A petty (utility) knife probably gets used most often after your all-purpose knives. It can be used to cut small fruits, vegetables, and even some smaller cuts of meats (any many many more things, like cutting through plastic wrapping from a grocery trip!) If you have one, for a quick meal for two, you may just get it done without a chef's knife.
