Abstract: A saw blade having a blade body, a plurality of cutting teeth defining a cutting edge along an edge of the blade body, each tooth along the cutting edge defining a cutting tip. At least one tooth tip along the cutting edge includes a different material, such as, for example, high speed steel, carbide, diamond, and/or a tip coating, than at least one other tooth tip along the cutting edge. The plurality of teeth may be arranged in a repeating pattern or in no pattern along the cutting edge. A method of manufacturing the saw blade includes forming a cutting edge along an axial edge of a blade body, defined by a plurality of cutting teeth having respective tooth cutting tips, wherein at least one tooth tip along the cutting edge includes a different material than at least one other tooth tip along the cutting edge.
