As for splitting the pelvis a large knife works wonders. There's a knack to it and it's hard to explain, but you actually go just to one side of the center of the main bone and kind of between the "joints" along it's length, jab hard and twist hard. It'll open right up. But you have to hit that sweet spot.
A Kabar type knife is called for, not your normal Buck 110 folder.
