A high wear-resistant grader blade which combines two high wear-resistant elements in the lower end of the blade. First, high wear-resistant particles are embedded into the front leading edge of the blade. More particularly, the leading edge of the blade is heated to pool molten metal. Tungsten carbide particles are then added to the pooled molten metal so as to blend with the molten metal. Upon cooling, the tungsten carbide particles mixed with the melted grader blade metal, will penetrate into the surface of the grader blade and will form a protrusion outward from the surface of the grader blade. Thus, the leading edge of the grader blade will be formed of a mixture of tungsten carbide and the grader blade material. Second, a groove is milled down the center of the grader blade and high wear-resistant inserts laid end-to-end are brazed into the groove.
