A plow blade edge system includes a plurality of wear bars mounted to a rear side of a plow blade section body. A first channel extends below each of the wear bars and is partially defined by the plow blade section body. Each where bar includes a weldment of carbide matrix along a bottom edge of the wear bar forming a first wear surface. The weldment of carbide matrix is retained in the first channel. The plow blade section body further includes a second channel formed in and extending along a bottom edge of the plow blade section body. The second channel is operative to receive at least one carbide insert and forms a second wear surface. A total surface area of the first wear surface exposed to the road surface is greater than a total surface area of the second wear surface exposed to the road.
