Whenever I decide to go for some pressure, I always do the same, regardless I'm in the bevel setting stage or finishing. I don't really discern between different levels of pressure. Instead I just try to make sure the finger applies the pressure and not the wrist. A while back, I have measured that pressure: I place the Coticule and the razor on a kitchen scale, zeroed it, so I would only measure the weight I was applying myself. It was in between 250 and 330 grams.
In general I finish without any significant pressure. Doing Unicot, never use pressure after the tape is on. Doing Dilucot, pressure may help to pick up the edge, when it stopped following during the dilution stage. Going back to very thin slurry (sometimes only 1 or 2 rubs with the slurry stone) probably has the same effect.
To sum up, I think I use 4 levels of pressure:
1. pressured halfstrokes (250-330g)
2. normal halfstrokes (just a finger resting on the blade)
3. X-strokes (no finger on the blade, allowing the weight of the razors to do the work)
4. swift, "breezing" X-strokes (only used for the taped stages of Unicot, for finishing and to finalize touch-ups.
Kind regards,
Bart.
