Hope giving advice on your BOB isn't considered rude with out you asking but I can see ways to greatly improve it just on the wood processing side and weight.
Points I see as problem.
1.Knife for chopping and hatchet are both rather heavy and do the same job in the same way.
2.Chopping makes noise that on still days/nights with high condensation in the air can carry miles.
3.Chopping is a very high energy expenditure, highest calorie burn you can do under most circumstances.
4.If you are hurt such as a cracked rib chopping could become near impossible, and trying to chop with just one hand/offhand is dangerous, reduced accuracy for most people using off hand.
5.Chopping when you are tired/exhausted/rushed is likely to result in an accident.
6.Its unlikely a knife big enough for chopping can fit into the axe head to batton and break apart a broken handle thats stuck for whatever reason(swollen from moisture or colder then when the head was attached so its shrunk on tight)
Personally I would drop the heavy knife, go one not over 6 ounces(yes you can get a knife that light or lighter that is tough and trustworthy)... and if really worried about wood processing carry a folding saw. IF very cold climate I would carry a saw blade and make a bow or buck saw if I need to do alot of wood. To carry saw blades use a piece of electrical conduit heated and flatten it as a sheath, or you can make into a circle to fit the larger saws as a sheath so it fits on the back of your pack as a circle, just cut out one side and you slide the blade in teeth first so the flat side is facing out and wrap some ties/wire/string around it to keep the blades coming out.
You can then take an extra metal container with the saved weight and likely still come out ahead and still have the same redundancy as you wanted with the ability to boil water in another container.
Just my thinking on what I would do and why.
Feel free to completely ignore it... most people do
I have a metal container for boiling water. I just like the idea of redundancy in my gear. Hence having both a tomahawk and a heavy knife that can work as a chopper or a slicer.
