A vice has a pair of parallel, work-piece clamping jaw-members, which jaw-members are spaced laterally apart. The first jaw-member is a semi-rigid one, while the second jaw-member is completely slidable as an integral unit, and also allows for the two jaw-elements thereof of which it is comprised to be movable toward and away from each, whereby the second jaw-member may be used separately to hold a workpiece, and may be used in conjunction with the first jaw-member for assisting the first jaw-member in firmly and safely clamping a workpiece in order to provide a more stable holding of the workpiece during the working thereof. The second, floating jaw-member may be adjusted for holding the smaller-diameter portion of a long workpiece, while the fixed jaw-member holds and clamps the larger diameter portion of the same workpiece. The second workpiece may be used alone for holding and clamping workpieces that are more difficult to grip, or the like, and also may be used for holding a tool, or similar article, while the first, semi-rigid jaw-member clamps a workpiece associated with the tool being clamped by the floating jaw-member.
