This style of folding eating set dates back to the mid-19th century, but remained popular for campers and outdoorsmen even into today. The handle slides apart and separates, allowing the user two different utensils. The fork and spoon are on opposite ends of one handle and the knife is on the other. These are made of regular carbon steel, not stainless, so over time, the steel will darken from use. Be sure to dry them immediately after washing and do not put them in a dishwasher.
