<p>Disclosed is a blade for a cross-cutting saw that includes a plurality of alternately splayed cutting teeth wherein a certain number of said cutting teeth disposed at various points along the length of the blade are splayed with an angle less than that of the main cutting teeth, such that the less splayed intermediate cutting teeth cut away the ridge that is formed laterally between the main cutting teeth, to cut a kerf with a substantially flat bottom that does not unduly resist the action of the saw. Also disclosed is a method of manufacturing the blade of the present invention by splaying alternately all the teeth by a substantially uniform angle to the central plane of the blade, machining the edges of the teeth to provide a suitable cutting edge, and then pushing back the teeth designated as intermediate auxiliary cutting teeth so that they are splayed by a smaller angle than the remaining main cutting teeth.</p> |
