I had my five inch serrated utility knife (AKA tomato slicer) since my parents gave us a Henkel set back in the 1970s, and was really sad when I took it to a meeting to slice a cake I was sharing and lost it. It is, as others have said, the most useful knife in the set. I was thrilled to be able to find the same knife that matched my old set perfectly! These really are great knives.
