I've wondered if there is a certain technique required for this. I have 2 straights that if I just try to push the hair down on the blade it won't cut. However if, once I feel the hair catch, I pull the blade up and on a slight angle the hair pops right off. So I'm curious if there is more technique required than just pulling a hair down on a blade or if there is some kind of quirk to it? Is the idea that no matter what you do, the hair should pop right off regardless. Or is there a certain technique that is required when doing it?
