Vintage Arnart Imports Carving Set

This was a wedding gift for my parents, so it is dated pre-May of 1965. The set consists of two knives, with one having a slot to pick up a slice of whatever you are carving, and a two-pronged serving fork. It comes in the original wooden box, which has a sticker marked "Lifetime Guarantee", "Stainless Steel", "High Polished", "Hallow Ground" (referring to the handles), and "Arnart Imports, Fifth Ave.". I don't recall my mother ever using them; they were always kept in the box at the back of the highest shelf of the kitchen of the homes we lived in. Feel free to ask any questions; I will do my best to answer them satisfactorily. Thank you for looking!
