An improved vise of the type comprising an elongated base defined by opposed, spaced-apart end edges and spaced-apart side edges, including a planar upper surface, and adapted to be mounted on the work surface of a machine that performs machining operations; an elongated first jaw fixedly mounted at one end of the base and having a jaw portion extending a short distance above the upper surface thereof; an elongated second jaw moveably mounted on the planar upper surface of the base, spaced-apart from the fixed jaw and parallel thereto, having a jaw portion extending a likewise short distance above the plane; opening/closing means passing underneath the planar upper surface and received in the second jaws in captive movement with the first jaw for drawing the jaws together and forcing them apart, and including a handle for turning the shaft means with respect to the jaws; the improvement comprising a plurality of elongated, floating jaw members, each member defined by a smooth base for sliding movement over the planar upper surface and a pair of parallel jaw side surfaces, held in spaced-apart arrangement by a top jaw surface, the jaw side surfaces arranged orthogonal to the planar upper surface, the members capable of clamping at least one part between and partially above the jaw surfaces of two, adjacent jaw members so that a plurality of similar parts for machining can be held in rigid, clamped arrangement between and partially above a plurality of the elongated jaw members and between the first and the second jaw members on the base for permitting accurate machining of all the parts in one machine operation.
