I haven't found a need to split a pelvis in the field in years on deer or elk. I do carry a folding saw that uses recip saw blades. It's more for survival than anything, in case I need some firewood to save my tail. I'm certainly not going to pack around a hatchet while chasing elk. My pack's too heavy as it is.

This is Milwaukee's folding saw. There are other good ones, too. I carry a spare 9" wood blade.
