You definitely do not need a $250 "camp knife" to start a fire. And I say this as a person who owns multiple $250++ camp knives. I own well made (but expensive" large knives because I like them and I want to.
There's a big difference between our modern, weekend camping and say a 1700's fur trapper who lived either alone or with a few comrades deep in the wilderness for months on end.
A hatchet is absolutely a much better tool for processing wood than a knife. It's better at chopping and it's better at splitting. I think the current craze in "bushcrafting" is to baton logs all the time. I view batoning wood as an emergency process, for when you need to get a fire started right now and there is no viable dry kindling. If I needed to split large pieces of wood to secure dry kindling and I had a hatchet, I'd use a hatchet. A knife is my tool of last resort in this situation. With a good, sharp hatchet you can split wood, make kindling and shave down feather sticks.
IME, the camp knife is the jack of all trades and master of none. You can clean game with it, but it may be awkward. You can chop vegetables and perform other meal prep, but it's not going to be as efficient as a dedicated chef's knife. You can break down wood for a fire, but it's not as efficient at this task as a hatchet.
A camp knife can be a fine choice for occasional weekend camping, since it does most tasks pretty well. Although a hatchet also can act as a hammer, and a knife not so well.
Far be it for me to discourage a man from buying a new knife I'd suggest taking a look at Bark River knives on DLT Trading or KnivesShipFree. I have several of their knives and they are excellent blades. Look for something in 3V for a very tough blade, with excellent edge holding characteristics and fairly stain resistant.
