use a dremel with a diamond blade, a wet tile saw, rotozip with diamond blade, or at least somehting that is SUPER SHARP adn can make a clean cut without cracking or chipping the skeleton (usually a power saw of some kind with a SUPER SHARP BLADE, brand new blade too). Cut at least an inch, preferably more, below where there is any flesh, good luck, and post pics. before and afters are great to have for yourself if noone else.
