exposure at A. The blade-bar gap is the distance from A to B.
It is interesting because no matter what the setting from 1 (extremely mild) to 9 (pretty damned aggressive), the blade exposure is always positive. (For those who haven't read most of my articles, a positive blade exposure means that the blade edge is above the shave plane, which is formed by the top cap and safety bar.) At a setting of one, the positive blade exposure is small -- as is the blade-bar span. The the opposite extreme, the positive blade exposure is greater, and the blade-bar span is much greater as well.
On its max-aggressive setting, the blade exposure is more positive
and the blade-bar span is much greater. Handle with care!
As I've come to understand this razor, I now use it at settings of 1 or 2. This allows me to take advantage of the more aggressive aspect of its milder settings, which is the slightly positive blade exposure, which helps to get a close shave with little risk -- as long as I maintain very light pressure of razor against face.
The aggressiveness of the positive blade exposure at these mild settings is mitigated by the small blade-bar span.
The result is that I can get a low-risk shave, but one that is reasonably close without doing too many extra razor strokes. I got a very nice shave this morning with the Slim and a SuperMax Titanium blade.
