A folding knife, often referred to as a pocket knife, is a versatile tool designed for convenience and portability. Its hallmark feature is a blade that folds into the handle, making it compact and easy to carry in a pocket or bag. Folding knives come in various styles, including traditional slip-joint knives, which rely on tension to keep the blade open, and more modern designs featuring locking mechanisms for added safety during use. These knives are popular for everyday carry due to their practicality, offering a reliable cutting tool for tasks ranging from opening packages to outdoor activities like camping and hiking. With a wide range of designs, materials, and price points available, folding knives cater to diverse needs and preferences, making them a staple in many people's daily lives.
