Vise-Grips are a type of locking pliers that can grip and hold objects securely. They feature an adjustable screw mechanism that allows users to set the jaw width, making them versatile for various tasks. The design includes a lever that locks the jaws in place, providing a strong grip without requiring continuous pressure from the user. These tools are commonly used in mechanical and construction work, as well as for home repairs. Vise-Grips come in different sizes and styles, including curved jaw and needle-nose variations, catering to specific needs and applications.
