It is important to note that this is a toe in a vise so the jaws will not naturally close flush. Not big, that's a feature. Pros: Portable, educational enough for medium-duty jobs. So if you have a workbench with plywood and a 2x4, it won't work without modification. If you have a 4" vise but sometimes need a 6" vise, this is perfect. Or if you need a vise out of the field, this is a good buy.
