A pocket knife is a small, versatile tool that fits easily in your pocket. It typically features a folding blade, which makes it safe to carry around. Pocket knives can be used for various tasks, such as cutting rope, opening packages, or even preparing food. Many people find them handy for outdoor activities like camping or hiking. In addition to the main blade, some pocket knives come with extra tools, like screwdrivers or bottle openers, making them even more useful. Whether you're a hiker, a craftsman, or just someone who likes to be prepared, a pocket knife can be a valuable companion.
