Depends on where I'm going and what I'm doing.
Backpacking fast and light?
-Bahco Saw
-Medium Sized Fixed Blade (7" blade or thereabouts)
Extended backpacking / camping?
-19" Gransfors Axe
-Bahco Saw
-Small Light Duty Knife (Mora #1, usually)
These tools are mainly for fire making, but occasionally I catch Trout, Grouse, or Rabbit that will need to be cleaned.
It's very wet where I live, and in order to have fires during rain / snow storms I need to access the inside of wood. The Bahco Saw is the most useful item I've found for this, so it's always with me, even on day hikes. A medium fixed blade is used to baton wood if my axe is not available. If my axe is available, I switch over to a smaller, more agile knife for carving and cleaning.
In addition to these, I always have my EDC folder on me, but that's just a force of habit from carrying it every day in the city. I rarely use my folder in the woods. Mainly to cut cordage, or gut the occasional trout.
