A unitary supporting member (integrally molded of urethane) is carried by a vise bar and is lodged between the vise bar and a wooden workpiece, thereby protecting the workpiece from being marred or scratched. The member is substantially homogeneous, is substantially devoid of internal reinforcements, and has a central recess having a plan outline corresponding substantially to a cross-section of the vise bar.
