It typically consists of two jaws, one fixed and one movable, which can be adjusted using a screw mechanism. Bench vises are commonly found in workshops and garages, making them essential tools for tasks like woodworking, metalworking, and repairs. These vises come in various sizes and designs, catering to different needs and materials. Some may have additional features, such as swivel bases or built-in anvil surfaces, enhancing their versatility. A well-maintained bench vise can significantly improve efficiency and safety during various projects.
