The blade material 17 is fixed to the base material 16 by bolts 19, and when the blade edge of the blade material 17 is damaged, it can be dealt with by changing its direction. Therefore, the blade material 17 can be thickened to be bolted. Although it is suitable, in reality, as shown in FIG. 8, in most cases, a crack 24 is generated from the damaged portion of the cutting edge toward the bolt hole 18, and even if the orientation of the cutting material 17 is changed. However, it is difficult to reuse because a gap or rattling easily occurs between the blade material 17 and the base material 16. Also, when the blade material 17 falls off, the base material 16
Also, since the base material 16 is damaged and deforms, the base material 16 has to be replaced. Further, even if the blade material 17 is normal, the base material 16 may be deformed. It becomes stable and difficult to reuse, and since the blade material 17 is thicker, the distance from the bolt insertion hole 21 of the base material 16 to the front end surface of the base material 16 becomes shorter, and the strength of the base material 16 increases. There was also a problem.

で、母材の強度が向上して変形防止に有利となる。Even if the cutting edge of the blade material is damaged by an impact, since the blade material has no bolt holes and is joined to the base material, even if a crack occurs, it can be minimized. It is possible to prevent self-destruction without the blade material falling off from the base material. Further, since the thickness of the blade material is thin, the length between the tip surface of the base material and the bolt insertion hole can be increased, so that the strength of the base material is improved, which is advantageous for preventing deformation.
