A method of manufacturing a tungsten carbide tipped circular saw blade (S) by: supplying a stainless sheet steel strip or blank to a laser cutting machine; laser cutting an arbour (11) and the periphery profile of the blade (S) according to a predetermined computer controlled pattern; brazing the tungsten carbide saw tips to their respective locations on the periphery of the blade (S); electro polishing the blade (S) to remove brazing residues and heat discolouration from the surfaces; and grinding the final cutting profile to each of the tungsten carbide tips.
