Brows get cut and separated by the hair cutter. Ears, the wife plucks for me. I think the cure for baldness is hidden in my earwax, lol.
I let a girl friend do that just one time. Ouch. She seemed to enjoy it but she was a bit of a sadist. I keep a single blade Bic cart in my medicine cabinet that works well. If I could figure out why the top of my head hair is migrating to eyebrows, ears, nostrils, shoulders... fortunes could be made.
