摘要
Two surfaces forming a cutting edge and a ridge of a cutting edge existing along the boundary between the two surfaces intersecting with each other are irradiated with a gas cluster ion beam at the same time, the maximum height of the profile of the two surfaces being equal to or smaller than 1 μm. A facet is newly formed on the ridge of the cutting edge by performing the irradiation with the gas cluster ion beam in such a manner that the two surfaces are not perpendicularly but obliquely irradiated with the gas cluster ion beam, and at least a part of the ridge of the cutting edge is perpendicularly irradiated with the gas cluster ion beam.
