.... just stop it. Seeing that clip is like dropping the a-bomb for real. I saw that when it came out, and at that time I was a very bookish young boy. That totally, completely and entirely freaked me out. A few seconds of incredible imagery that speak volumes about what would probably happen. And a really good look at the fact that you will NEVER be prepared for a dramatic end.
It never ceases to amaze me how many times the "end of the world" and "you could only have one knife" and its hundreds of variants populate this forum. Endless variations on a them.
I always wonder as well how so many think that if there is an apocalyptic nuclear blast, an unexpected tidal wave, a chemical attack, etc., that they will be near their bug out bag. I have an acquaintance that has 3 of them; one for work, one for home, one for the truck. Since numbnuts told everyone what the contents were of his work BOB, they told him he had to leave it in his car and couldn't carry his BOB in the building. He was upset and I couldn't help but needle him. "What are you going to do if the blast turns your car over and you can't get to your BOB?" and "what is a tidal wave washes your car away" and what if infected people that you loaded your BOB to protect yourself from are wandering the parking lot?" and on and on.
Most people I know don't even know how to set up a camp, and have never done more than an overnight or two if they do. An edged tool is very important, but water/food/shelter are certainly more valuable. Just read some of the real survival stories; IF a knife is involved by someone that got lost on a trail, was left behind by the group, or just wandered off, they almost always credit a SAK or a multitool. Never, ever in my 65 years have I read anyone say that a heavy duty knife like I carry daily for work (like my Cold Steel SR!) saved them or helped them.
Since the question is about which steel, just get a knife that has steel you can easily sharpen in readily found gear. Back in the 60s - 80s, I camped/hiked/hunted all the time. I didn't know any better, so most of my knives were 1095 or one of its cousins, whichever steel CASE or Boker used. Someway, they worked fine. And since I was a free hand sharpener I touched up my knives in the field as needed (if needed!) with a piece of 600gr wet/dry sandpaper stolen from the job site. My knives were always plenty sharp for skinning, cutting, shelter building and other camp chores. Best of all, they were snap to sharpen.
