Definitions

  • the embodiment of the blade edge according to FIG. 4 does not contain any straight regions as in previous embodiments, but it is an arc-shaped curve which is asymmetrical in that the left part 8 has a different radius of curvature than the right part 9.
  • the arc-shaped curve can also be symmetrical, the radius of curvature is the same everywhere.
