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 (jack-knife) or a penknife, though a penknife may also be a specific kind of pocketknife.[1][2] A typical blade length is 5 to 15 centimeters (2 to 6 in).[3] Pocketknives are versatile tools and may be used for anything from opening an envelope, to cutting twine, slicing a piece of fruit, or even as a means of self-defense.[4] They are often used as everyday carry (EDC) knives.
