Might seem like a silly question...but having watched barbers they seem to move the blade really fast sometimes compared to me. I can move it quick on the cheeks but thats it. Slow and steady with a little pressure seems to work best for the rest of the face. So, I'm wondering should I be going for slow and steady with some pressure or fast and light or slow and light for that matter...I've also read I should be moving the blade as far as possible...short strokes or as far as possible? What do you guys think?
