Folding knives are versatile cutting tools that feature a blade that folds into the handle for safe storage and portability. They come in various sizes and designs, making them suitable for everyday carry, outdoor activities, and various tasks. The folding mechanism allows for easy opening and closing, often with a thumb stud or a liner lock for secure use. These knives are commonly made from stainless steel or carbon steel, providing durability and resistance to corrosion. Many folding knives also include additional features, such as pocket clips for easy attachment to clothing or gear, enhancing their practicality for users in different situations.
