Title:
FLAT-BLADE CUTTING BLADE
Document Type and Number:
WIPO Patent Application WO/2020/130092
Kind Code:
A1
Abstract:
In the present invention, the external shape of a first blade section includes: first inclined surfaces that are linearly inclined with respect to the center line such that the blade becomes thinner in the direction away from a base in the extending direction (Z direction); and a pointed end serving as a blade edge. In a vertical cross-section, the external shape of a second blade section includes second inclined surfaces that are linearly inclined with respect to the center line at a more gentle angle than the first inclined surfaces and that join the first inclined surfaces. In the vertical cross-section, the external shape of a third blade section includes concave curved surfaces that are curved in a concave shape toward the center line and that join the second inclined surfaces. In the extending direction (Z direction), the length L2 of the second blade section is less than the length L1 of the first blade section and is from 20 μm to 120 μm.
