What is a folding knife?

A pocketknife is a foldable knife with one or more blades that fold into the handle. It is also known as a jackknife (jack-knife) or a penknife, though a penknife may also be a specific kind of pocketknife. A typical blade length is 5 to 15 centimetres (2 to 6 in). Pocketknives are versatile tools, and may be used for anything from opening an envelope, to cutting twine, slicing a piece of fruit to a means of self-defence.
