There is a small bend in the handle for tightening the swivel base. Jaws have been worn mostly flat and may need to be re-cut or replaced depending on your needs, but they do close tightly and relatively evenly.
The central four inches of the jaws close flush, leaving less than a millimeter gap for about half an inch on either side. Comes with period-matching hard-rubber inserts that mount with magnets. Vise is heavy for its size, weighing 40.5 pounds on my scale.
Closed, it measures 14 inches long and 8 1/2 inches high.
