I see that most folk commonly start their shave with an adjustable set higher and adjust down on subsequent pass(s).Recently I saw it recommended that the opposite be done. Can anybody weigh in on this?
Do whatever works for you. In brief, there is NO correct way to use an adjustable - just what works for you. That, to me, is the beauty of the adjustable razor: you can be as flexible as you want.
I start a new blade at a low setting and when the blade mellows I turn my Slim up one setting at the time. In this way I can enjoy the closeness when the blade dulls!
I used to start low and go up. Recently I have been doing N-S (technically the easiest pass for me as far as angle and control) at 3 on the Futur or Progress, then dialing down to 1 for the XTG and ATG passes. Blade buffing is easier on a low setting.
