A portable apparatus for determining an edge profile of a metallic workpiece, such as a steel slab. An end portion of a tracking rod engages with an edge surface of the workpiece, and is translated along a vertical cross section of the edge surface. Variations of the surface of the edge of the workpiece causes deflection of the tracking rod. A pen mounted to the tracking rod is positioned proximate to a chart recorder thereby allowing the deflection of the tracking rod to be recorded as the tracking rod is translated, to thereby record the edge profile of the workpiece.
