Vise grips are a type of locking pliers used to hold objects firmly in place. They feature adjustable jaws that can grip various sizes of materials, making them versatile for different tasks. The locking mechanism allows users to secure the grip without continuous pressure, freeing up their hands for other work. These tools are commonly used in mechanical and construction settings, as well as for home repairs. Vise grips can be particularly useful for tasks like loosening rusted bolts or holding pieces together while welding. Their design and functionality make them a staple in many toolboxes.
