You can get a handmade knife for under $100. With the prices on many manufactured items currently, at least in the US, handmade knives are pretty competitive.
Someone else mentioned it and maybe some more later as I stoppes reading on page one, but I would start with a few knives and get experience before putting all my money into on "THE knife."
I also do design work and there are some things where you can't substitute experience. I find knives and knife design to be one of them, especially if you look at some of the production knives out there that look cool but aren't ideal for use. However, an ugly functional knife isn't always great either.
CPK makes some of the better functional knives, but there are aspects of them that don't suit my tastes. Great knives, my favorite was the Kephart but I made a deal with a good friend since it was the only way he was ever going to get one. I'll get another eventually. I think the DEK is probably the one I should try as well, their field knife is thicker than I want. But, it is an "everything" knife and in that regard, really well done.
It may have been recommended by now but the jaakaarri puukko (probably spelled that wrong) from Varusteleka is a really solid knife for not a ton of money and there are a few sizes to pick from. If I were starting out my collection of usee knives, that would be really high on my list. I have the fortune of having my own stuff for what I think a knife should be for a given task, along with having cycles thru and tried hundreds of knives so some of the "blah" looking knives stick around as long. Not because they aren't but because they aren't great.
Another that falls into this is the Kabar Mark I. I wouldn't baton the daylights out of it but if you're sensible about what you're splitting and what you're hitting the knife with, you'll be fine. Knives hold uo to batonning pretty well if you're not really careless about it. More, lighter power hits still get the job done. And, if you're using something like a twig stove, you don't need nearly the amount of fuel as in an open fire pit.
I usually carry a camp knife (5"-6" blade) and a folder (cold steel golden eye lately) for most of my trips. Sometimes a SAK or other small multitool as they help with field repair, but it all depends on what I have and what may need repaired enough to get the rest of the way.
You mentioned lionsteel, I really like their fit and finish in a production knife. Their bushcraft series knife is very good. It's beefier than it would look in pictures and their sleipner steel is going to hold up well to beating.
I know there's plenty of people here that have already commented and there's many knowleadgable people here, so this may be a useless offer. But, if you want to chat with me about knives, feel free to message me at
