People get down right culty and creepy about their knife brands of choice, particularly when they feel that old time religious righteousness in their bones. People who champion one of the high priced, semi-custom, "god brands", I would invite you to tell me how, under real world conditions rather than contrived testing, these wonder blades are better than say, a $50 dollar Ka-Bar manufactured MkII Utility Knife. Let's use that as our baseline. Don't tell me "better" or "more" or "best", that is puffery- give me a scientific analysis that doesn't involve stabbing rocks or gutting a Caddy or anything along those lines. Does a $300 knife actually perform 600% better than a good $50? 100% better? 50% better? 10%?
I'm not saying that to fight with anyone, feel free to carry what you wish. If I could afford it, I might buy a Busse or SwampRat, they have impressed me (unlike some of the other culty brands). But if it offends you to hear someone disagree with your choice, and it sounds like a lot of you are offended, then you are taking a hunk of sharpened metal way to personally. Odds are, you won't have a choice what you have with you when TSHTF, becuase by definition that is a surprise. If you saw it coming, you'd have prepared, which means that you'd have more than one knife on you as stipulated by what I think are the rather unrealistic guidelines of this theoretical thread. So you'll use what you have, even if you don't like it.
I'd also point out that people who get too focused on their gear, who must have this or must have that, aren't focusing on surviving. Yes, you should have a knife, a good one, just like you should have a way of starting fire. But people who have the best, greatest, highest speed, lowest drag stuff can turn into yet another body drag, just like Magnussen pointed out. And not just a noobs with more money than brains, but experinced and skilled people. And if you can't survive with out your blade of choice, maybe it is turning into a fetish. Which is not a healthy place to be when the only way you can get your survival mojo up is with the aid of your XYZ Supercutzu. So what is this bickering accomplishing, other than turning into "my dog is better than your dog"?
Or put another way... *takes a stick, marking a line in the sand* Gentlemen! Everyone line up, toes on the line, pointing that direction. *gestures with my stick* You may pee when ready. The one who went the furthest gets bragging rights.
