I think the very fact that we are on this forum, or that this forum even exists, shows that for US, the one knife for life thing can never happen.
Forum = discussion site.
Topic = knives.
We talk about knives, share pictures of our knives, post pictures of knives we want, talk about what our forefathers carried, used, what they accomplished with them, etc. We make up stories about knives (Jackknife) and are totally and completely smitten with knives.
OF COURSE we can't keep it to just one knife after all that!! Haha.
To those that see it as a tool, no other knife is needed, nor is there a need to discuss them. It's like me and a wrench. I don't care if it's made in China, Russia, Australia, Mars, Jupiter, the Crab Nebula, etc. If the wrench works, let me use it to turn this darn bolt!! Haha. Now there MIGHT be a forum out there devoted totally to the mighty wrench. For me, this forum would be a waste of time because I could care less about wrench makers, origins, different models, etc. It is just a tool I won't ever even look at until I need it. Some people view knives that same way. It's just a tool. Where is it made? Who cares, as long as the edge is sharp.... and even THAT doesn't always matter.
However, like I said, to those of us that reside within the pages of this forum, there is NO WAY ON HELL we are ever going to carry just one knife.
Oh, we try. Many have, and many more will, but there is too much temptation within these posts for that.
Friggin evil forum!!
LOL.
