The blade manufacturing method 50 includes a pressing step 51 for engraving a fold line 61 on one surface of a plate material 60, a heat treatment step 52 for heat treating the plate material 60 from the pressing step 51, and a blade attachment to the plate material 60 from the heat treatment step 52. Step 53 with blade for making 62
And a dividing step 54 for separating the plate material 60 from the blade attaching step 53 at a folding line 61 to obtain a blade body 70, and an outer shape finishing step 5 for grinding a corresponding portion of the folding line 61 of the blade body 70 from the dividing step 54.
It consists of 5, and so on. However, since the folding line 61 is stamped on one side of the plate material 60 in the pressing process 51 in such a pressing process, it cannot be accurately folded at the folding line 61 in the dividing process 54.
A sharp concave-convex portion 73 is often formed on the upper and lower sides 71 and 72 of the blade body 70 adjacent to each other with this as a boundary.
As it is, it does not look good, and it is dangerous to cut a finger, and the accuracy of the external dimensions is difficult to obtain.
Therefore, it is necessary to remove these concave and convex portions 73, and there is a problem that it takes time and labor to manufacture.

FIG. 3 is a plan view showing a plate material that has undergone a pressing process. Figure 4
4-4 sectional drawing of FIG. FIG. 5 is a plan view showing the plate material that has undergone the blade attaching process. 6 is a sectional view taken along line 6-6 of FIG. FIG. 7 is a plan view showing the blade body that has undergone the dividing step. 8 is a sectional view taken along line 8-8 of FIG. The blade body manufacturing method 1 includes a press step 2, a heat treatment step 3, a blade attaching step 4, and a dividing step 5,
The plate material 10 is used as a starting material. As shown in FIG. 2, the plate member 10 is provided with left and right sides 11, 12 and has a thickness of 1.5 mm and a width of 3 mm.
It is made of a 7.5 mm strip-shaped stainless steel plate and wound into a coil. In the pressing step 2, the fold line 13 is stamped on both sides of the plate material 10. In this example, the rolled plate material 10 is rewound and supplied to the press machine 30. As shown in FIGS. 13 and notch 14 and through hole 15
And are formed at the same time. The fold line 13 has an obliquely long outer shape fold line 16 between the left and right sides 11 and 12 of the plate material 10, and a short outer shape fold line 17 that reaches the left side 11 at a right angle from the middle thereof. The notch 14 is located at the intersection of the long outline fold line 16 and the right side 12. The through hole 15 is located near the short outer shape folding line 17 in a portion surrounded by two adjacent long outer shape folding lines 16, a short outer shape folding line 17 and the right side 12. Long outline fold line 1
6 is symmetrical to approximately V on both sides of the plate member 10 by a pair of chisel 33, 34 provided on the upper and lower dies 31, 32 of the press 30.
It is stamped on the mold. The short outline fold line 17 is stamped into a substantially V shape on one surface of the plate member 10 by the chisel 33 provided on the upper die 31. The angle, depth, etc. of the V-shape of the long contour line 16 and the short contour line 17 are appropriately selected. The notch 14 and the through hole 15 are punched by a pair of punches 35 and dies 36 provided on the upper and lower dies 31 and 32, respectively. The heat treatment step 3 is the pressing step 2
The plate material 10 is heat-treated. In this example, the plate material 10 that has undergone the pressing process 2 is supplied to the heat treatment furnace, and the entire plate material is continuously quenched. The plate material 10 that has undergone the heat treatment step 3 is once wound depending on the difference in working speed from the next step. The blade attaching step 4 attaches a blade to the plate material 10 from the heat treatment step 3, and in this example, the once rolled plate material 10 is rewound and supplied to a coil polishing machine or the like. As shown in FIG. 6, the right side 12 of the plate material 10 is continuously ground into a substantially V shape from both sides to form a blade (double-edged blade) 18. In the dividing step 5, the plate material 10 from the blade attaching step 4 is separated along the fold line 13 to obtain the blade body 40. In this example, after being divided at the long outer shape fold line 16, the short outer shape fold line 1 is formed.
It is divided at 7. Since the long fold line 16 is stamped on both sides of the plate material 10 in the pressing step 2, it is accurately separated from the location. Although the short outline fold line 17 is stamped on only one side of the plate material 10 in the pressing step 2, since it is short in the length to be cut, it is relatively accurately cut from the location. Further, since the short outline fold line 17 is a place where the blade body 40 is not required to have much accuracy, there is no problem. The blade 40 thus obtained is used for a cutting knife,
As shown in FIG. 7 and FIG. 8, the upper side 41 and the lower side 42 obtained by the long outline folding line 16, the front upper oblique side 43 and the concave arc side 44 obtained by the cutout 14, and the front lower oblique side obtained by the right side 11 45
And a rear side 46 obtained by the short outline fold line 17, a blade (double-edged blade) 18 is formed on the lower front hypotenuse 45, and a circular through hole 15 is formed in the middle of the rear side. In particular, since the upper side 41 and the lower side 42 do not have the uneven portions as in the conventional case, they can be used as they are without any external finishing step.
