I know it seems off topic, but I carry a leatherman on my belt and a Pocket Screwdriver in my breast pocket along with a CS Black Rhino. FTR I happen to be a mechanic, and while it may not seem applicable, I find myself doing the same things in the woods as I do in the shop. (Former Infantryman). I use the Pocket screwdriver for poking/prying before I pull out my knife or Leatherman. First, its A LOT cheaper than either of the two knives, I expect it to take damage based off of the task its performing. Its as small as a pen, so I don't worry about weight in comparison to the other two beasts I am carrying. The Leatherman is the next go to for poking/prying/sawing. It has all the appropriate tools in a very compact package (the tools contained within are also individually replaceable). IF I had to cut down a larger tree and was not carrying a large saw blade, then I would baton the tree with my CSBR.
As a mechanic, I have to reiterate, there is a tool for every job, but there is no single tool that can do every job. Some are good for multiple jobs like a Multi-tool, but thats where it ends.
I would say as earlier pointed out, for heavy duty camping take a Saw Blade/Axe or even a Military E-tool shovel with serrated edge. That way you don't kill your most important tool (your knife).
