A pocketknife is a foldable knife with one or more blades that fit inside the handle that can still fit in a pocket. It is also known as a jackknife or jack-knife. A typical blade length is 5 to 15 centimetres (2 to 6 in).
A lock knife is not a folding pocket knife and therefore it is illegal to carry around such a knife regardless of the length of the blade. A lock knife means a knife which is similar to a folding knife, in that there is a spring holding the blade closed.
