A utility knife is the third member of the kitchen knife trifecta. Between a chef's knife and a paring knife in size, it's perfect for all those in-between tasks. Any time a paring knife seems like too little and a chef's knife too much, reach for a utility knife. The Shun Dual Core Utility Knife offers a razor-sharp 6-in. edge that is also perfect for slicing meats, cheeses, tomatoes, and more, which is why this style of knife is sometimes also called a sandwich knife.
