A multi-jaw vise structure comprising both fixed and movable jaws that are adapted to clamp a workpiece and a portion to be severed therefrom in such a manner that excessive tool wear and uneven cut surfaces resulting from vibration and/or the break-away of the severed portion are substantially eliminated. One of the jaws of the vise includes a movable bearing face which is biased by a compression spring into contact with the workpiece to cause at least some of the workpiece to remain clamped within the vise when the vise is partially opened while permitting the cut off portion to be freely removed.
