It's one of those things that seems - to me, at least - like a lot of pain and expense for very little gain. I have a squareish jaw, but even square or prominent jaws aren't unusual for females. It's not as if many people look at someone and say, "Ugh, look at that girl's jaw. I bet she used to be a guy."
There are some tell-tale male facial features, but I've never really though of the jaw as being one of them. Chin, sure; few girls have a superhero chin, but the jaw itself, I'm not convinced that it's money well spent considering everything else we could legitimately spend money on, such as nose, forehead, eyes, hairline, etc. I also have a strange worry that reshaping the jaw would weaken it, and I imagine it cracking really easily. Unfounded?
