If you need a knife and fork while traveling, this tourists' set is a solution.
It consists of a knife and a dinner fork, which are held together during transport by sliding them together, connecting them with a clasp or by putting them in a pouch. In some cases there is also the option to store a tablespoon (1).
See also the camping knife and pocket knife. [MOT]
