Key Differences

A pocketknife is designed as a versatile tool, commonly used for a range of everyday tasks, from opening packages to cutting twine. In contrast, a penknife, while similar in size and portability, was historically tailored for the precise task of cutting and sharpening quill pens.
Modern pocketknives often feature multiple blades and additional tools like screwdrivers or can openers, enhancing their utility for various applications. On the other hand, penknives typically maintain a simpler design with one or two small blades, focusing on lightweight and basic functionality.
The term "pocketknife" is broadly used in the United States and implies utility and robustness, suitable for both urban and outdoor environments. Whereas the term "penknife" is more commonly used in the UK, evoking a sense of traditionalism and specific use.
Pocketknives are commonly associated with outdoor activities such as camping and fishing, where a sturdy, multi-functional tool is essential. Conversely, penknives are often seen as a gentleman's gadget, ideal for small, precise tasks like trimming paper or opening envelopes.
Due to their robust construction, pocketknives are typically built to withstand tougher tasks and often come with locking mechanisms for safety. Penknives, while also durable, prioritize compactness and ease of handling over heavy-duty use.
