In traditional Sheffield parlance, a penknife has a hinge at both ends and includes a small spear point blade intended for sharpening quill pens. Any friction folding knife that doesn't conform to both of those requirements is a pocket knife.
In the UK you can carry a sub 3" blade, non-locking, folding knife in your pocket without needing a specific reason for having it. These are often referred to as 'legal carry knives' although you can still legally carry a larger or fixed blade knife as long as you have a valid reason for doing so on that specific journey, like a chef going to work for example.
