A pocket knife is a small, folding knife designed to be carried in a pocket. It typically features one or more blades that fold into the handle, making it compact and portable. Pocket knives are commonly used for a variety of tasks such as cutting rope, opening packages, and performing small, everyday tasks.

Many pocket knives also include additional tools like screwdrivers, scissors, or bottle openers, making them versatile multi-tools.
