Abstract: A vise system including a plurality of jaws associated with a vise body. A first jaw is attached to a first shaft which are both slidable with respect to the vise body. A second jaw is attached to a second shaft which are both slidable with respect to the vise body independent of the first jaw and first shaft. A locking mechanism is associated with the first and second shafts for locking the first and second shafts, and first and second jaws, in place. The locking mechanism includes a first collet partially surrounding the first shaft, and an aligned second collet partially surrounding the second shaft. First and second stops are operatively connected to a handle so that as the handle is turned, the first and second stops engage the respective first and second collets to compress the collets over the shafts to immobilize them.
