Gigant dude...
Welcome to BF and the wonderful world of sharp things. You're English is fine. I have a couple of questions. First, "survival"means different things to different people. From the rest of your post, I'm guessing that you're looking for an all-around camp and woods knife. Something that can cut / shave / whittle wood; that can be used for food prep; that can be used for rougher tasks like light prying or batoning wood, or any reasonable "emergency" situation.
Ease of maintenance should be high on your list of priorities at this point. The Cold Steel combination shown above is very good. Essee knives are also very good and easy to maintain. I prefer a two-knife combination when I'm out in the woods for any length of time. I carry a folder and a fixed blade. This combination has worked well for me for years. The fixed blade has about a 3" blade. I haven't found a need for a larger FB even though I have one or two. The folder I carry in the woods will usually have a 3.5" to 4" blade and a secure lock.
Steels like AUS-8, 1095, 154CM, or A2 are going to be easy to sharpen and relatively tough. That's another high priority for an outdoors knife. 1095 and A2 are not stainless so they'll need extra care to prevent corrosion. Many maker like to coat these steels. I prefer them uncoated but I know how to care for them.
I may be off base with my second question. I'm just trying to get a sense of what you know from your OP. If you're an experienced hiker / camper, ignore the rest of my post. My second question is a little more personal. Do you know what you're doing in the woods with a knife? I ask because you said in your OP that this would be your first knife. You're making the right choice to go into the woods prepared with the right kit, but having the gear is only part of being prepared. You've got to know what your kit will and won't do, and how to make it do what you need in the woods. An outdoor trip can sometimes go from "fun" to "fatal" in a hurry.
If you're not experienced in the woods, I'd suggest going with some experienced campers the first few times, or take a wilderness survival course (they can be a lot of fun themselves with the right instructor) before setting off on your own.
Have fun searching for the right gear and hope you enjoy using it out in nature. Be safe.
