Cole vices are not for blacksmith work. I have several and use then all the time. They are for gripping, not hammering. Take a look at the jaws, if they have replaceable jaws, they are not for blacksmith work. Blacksmith vices were designed with solid jaws and not replaceable. Which means not usually damaged by beating on them with a hammer. True blacksmith vices were designed with that in mind. Bear in mind that any vice can be damaged by hammering on it. Especially if you do not lock the vice and beat on it while it is open. This is a good way to damage the gripping edge. You don't have to ask me how I know, I think my dad's boot print is still in my butt for doing just that.
