Imho if you are planning to leave the provincial park campsite you need an axe and are fool not to have one. A diamond coated file should be attached to the sheath as well.
Why? I guess I'm a fool. On a backpacking trip every ounce counts. Kindling can be gathered from twigs off deadfalls, moss or if necessary sticks can be feathered with a light knife. Enough branches, bark etc. can be gathered for fuel or building a shelter but for that matter I'd rather take a light tent or fly.
The largest of game can be boned out with just a sharp knife. I was given one of those Gerber pack saws but I have yet needed to use it.
