My wife and I always hike together, and we share equipment. I carry the food and the tent, she carries the "kitchen" (stove and dishes) and the FAK.

We've got a gear list on our website, if it would help you. I agree that we would only take an ax if one of us were planning to murder the other one. So far, I haven't carried one....
