Yeah, they are awful! Fortunately, my girlfriend (a woman with obviously impeccable taste, in all areas :-) can't stand them either.
I just always imagine an irate woman letting fly on her boyfriend/husband/obnoxious-would be-suitor/assailant with one of those things - especially the ones with actual metal tips - and ripping a guy's spleen wide open! Not that I have the slightest idea where the spleen is actually located, or what on earth it does.
It's under the left side of your diaphram and here's some good info on what your spleen is for.
Essentially that would be a nasty thing for a gal to do and would leave you open to blood infections long-term.
