I think if I we're going to carry an axe as an emergency item. I would probably pick a felling axe, in addition to a hatchet.We were recently in the wilderness on a dirt road, and got stuck by a tree across the road. Fortunately guy in front had a chainsaw and just enough gas to cut it in two places. I’m not sure an axe would have efficiently gotten through the tree, at least not quickly. It was maybe 12” diameter. Would have taken forever. I can’t see always bringing a chainsaw, but some sort of saw I think would be as/more useful.
