There are two main categories of vise ("vice" in UK English sp.) : vises on the end of the bench and vises on the front of the bench. End vises (also called 'tail vises') are usually mounted on the right side of the bench for right-handed workers. They can typically hold work in two ways: between the jaws and along the top of the bench using moveable 'dogs' in place of jaws. Not all benches have tail vises. A front vise (also called 'face vise' or 'shoulder vise') is typically mounted on the left front side of the bench. They may be used for holding a board to be edge jointed, or sometimes for sawing out dovetails and the like.
