I know exactly how you feel. I can stand the hollows of my neck. You cant see them very well, and if you make the attempt to shave the angles blind, it seems you always need the friendly styptic to laugh at you by cauterizing on the spot and burning the whole time.
Ironically, I've never cut my neck, sure a little nick, but never a cut. I have sliced my cheek pretty good when I get in a hurry. Lesson, don't straight shave when you're in a hurry and hungover.
