VisesA vise is a mechanical device that is used to hold an object firmly in place while it is being worked on. It consists of two jaws, one of which is fixed and the other of which is movable, and a screw mechanism that is used to open and close the jaws. Vises are commonly used in metalworking, woodworking, and other crafts, as well as in laboratories and other settings where it is important to hold an object securely and accurately. Vises are available in a range of sizes and styles, and can be mounted to a workbench or other surface, or used as a handheld tool. Some examples of different types of vises include bench vises, machinist's vises, and pipe vises.
