No doubt, You get a much closer shave with a Straight Razor. Yes, It takes some getting used to, and practice, and a bit more prep, but the end result is so worth it.
Not only angle and bad prep contribute to irritation, but sometimes the honing method.
Your edge can actually be too keen. Me, for instance. If I use .25 diamond paste, it irritates the hell out of my face. I have to admit, Shaving has become a high point in my day for me. I look forward to it.....
