Bunting — hands split or together?

Looking for general feedback here, and perhaps to get some good dialog going on a cold day in Chicago. In another post I mentioned a debate going on regarding teaching player to bunt with their hands together and up the bat, or the hands separated with one at the knob and the other up the bat.

Which do you teach? And why? I’ve seen both used in fastpitch games, and each side has it supporters. Just curious as to what other people think.
