, and additionally a super abrasive such as silicone carbide and alumina and also a mixture of at least two of the aforementioned materials. Furthermore, the shank is commonly formed of a metallic material such as stainless steel and carbon steel.
As a method of bonding the abrasive or grinding stone portion to a shank, a sintered-tip welding method (hereinafter, referred to as a “sintering method”) has been known. In this sintering method, a metallic bonding material and abrasives are generally mixed, press-formed and sintered to form a cutting tip, and then the sintered cutting tip is bonded to a shank through a silver brazing, a laser welding, or a resistance welding.
FIG. 1a is a partial front view of a conventional saw blade where a cutting tip formed by a sintering method is attached to a shank. FIG. 1b is a cross-section taken along line I—I of FIG. 1a. 
A typical saw blade has the shape of a circular plate, and a plurality of cutting tips are formed at regular intervals along the circumference thereof in such a manner that they protrude in a radial direction. FIGS. 1a and 1b show a part of the cutting tips. As previously described, in the sintering method, a metallic bonding material 120 and abrasives 130 are beforehand mixed, press-formed, and sintered. Thus, as shown in FIG. 1b, the cutting tip has such a structure that a plurality of abrasives 130 are non-uniformly dispersed in the metallic bonding material 120. This cutting tip is bonded to a shank 110 through a welded portion 115 formed through a laser welding, a silver brazing, or a resistance welding. Here, the cutting tip is provided with a blank 125 formed at the bonding area with the shank 110. The blank 125 has only a bonding material without the abrasives 130 so that a subsequent laser welding with the shank 110 can be easily performed.
As another method of manufacturing a saw blade, it has been known a method of simultaneously compacting and sintering together with a shank, which is different from the aforementioned method. In this simultaneous compacting and sintering method, a shank 110 is positioned at the center of a mold, and a powder mixture of metallic bonding material 120 and diamond particles 130 is filled in the mold. Then, the metallic bonding material 120 and the abrasives 130 are powder-compacted and
