I use the blade with a razor and mill Jaguar Shavette. In mill Shave keep the blades at least. 8-10 shaves at medium beard. In Shavette I use it 4-5 times, however, there is only half a blade in use.
For cutting capacity I can say. The careful preparation and accurate shaving everything away in first gear.
To get baby soft skin I go twice on the face. In the first shave Pass, with the bottom line to all of the hair to remove coarse. In the 2nd run perpendicular to the line to be more thorough.
I can only recommend the blades.
