語として中引は特性になる物があった。<Prior Art> As shown in FIG. 11, a conventional cutting tire tip]. 1 has various shapes such as rectangular, inverted trapezoidal, and grooved blade cross sections, but in all cases, the blade cross section wears into a semicircular shape during use.
The problem is that when the blade is swung from side to side, it does not grind straight.Also, when the blade reaches its final position, it forms a semicircular shape on the board as shown in Figure 12, and the material to be cut comes into contact with the board 5, making the board unusable. Therefore, as shown in Fig. 10, by changing the properties of the tip 13 to a three-layer structure (the middle part during metallurgy) and a soft layer, the contact surface of the cutting edge was changed to the shape shown in Fig. 8. As shown in Figure 1, there is a condition where the middle part wears out first, and the industry term for it is "chuibiki".
