I'm not sure I agree with the no pressure advice that's always given. If one was to truly use no pressure I don't see how the blade would move through the whiskers. It takes some amount of pressure to physically move the razor in a certain direction and overcome the resisitance of the whisker from being cut, and the friction between the razor and the skin.
I applied more pressure tonight than I thought was "safe". But not crazy pressure. Just barely pressure.
Still, I thought for sure I would have some screaming post-alum sting. Yet, I did not. Not at all.
