Precisely. Survival is very a very subjective subject. Earlier responses of containers, using your brain, and others are great! Yet you responded with the word "real", a lot, almost writing them off. If Ontario made a canteen, would that make it more survival-esque? Those are very real things, and just as everyone's different, so is their emergency preparedness strategies. To be fair, this is in general discussion, so I generally consider many of these fantasy posts to be just that, they're fun. When you're asking real people about real choices, hear them out, there's some very experienced and knowledgeable people here who have a strong willingness to share information. The biggest mistake you can make in survival, is being closed minded.
back to the knives, the ontario you speak of is probably pretty solid, but there might be some better options, depending on what climate you're in, geolocation, and what your skill set is. Fantasy or not, I'd be careful in giving advice to do something stupid, like go into the wilderness with one tool. That puts search and rescue peoples lives on the line unfairly.
