The distance (B) to the contact starting point (A), which is the intersection of the contact portions (14a) and (24a) along the inner edge of, is shorter,
At this time, since the distance from the pivot shaft (3) to the cutting point (C), which is the intersection of the blades (12) and (22), is short, the sliding contact surfaces (13) of the two blades (1) and (2) are small. ) There is almost no effect on sharpness using the warpage and twist of (23). Moreover, as the cutting progresses, the distance from the pivot shaft (3) to the cutting point (C) increases, but the pivot shaft (3) is accordingly increased.
Since the distance (B) from the contact point (A) to the contact starting point (A) gradually increases, the sharpness is also maintained well.
