As has been said many times before, there are dozens of manufactures, and thousands of styles for a reason, might as well find the one that works for you. my needs and seeming contradictory restrictions are going to be very different from anyone elses. I typically work with kids, often pre and teen boys. So big knives are out. They are just not worth the trouble, and some of the places I work don't want us to carry fixed blades. But they are also fully relying on me to get them through whatever might happen, and part of that means I can't have a tool that needs too much thought, or has a fiddle factor. So the knife that right now has fallen right in that gap is the vic rucksack. the blade is big enough to do nearly anything. The saw works very well, and I can get the tuna or beans open for lunch. Not much better that that. In truth, I would probably prefer the liner-lock version (so either the trecker or forester) but the reality is that it gets the job done. And I really wish I had my griptillian, but import restrictions and all that just make it easier to carry the Vic. Teachers don't freak out about it, and even the most nervous of kids know somehow that swiss army knives fix things. I don't know how, but they just do.
I've tried carrying a combo, including a BK13, which is a great little knife, but its going to stay on fishing box duty, and an izula, but the reality is that the izula, as great as it is, is too close in size to the ESEE-3, and that gives you a full handle. its really a better backup to a multi with a small blade than the 111mm vic. And who knows, maybe the ESEE-3 will get stashed in the pack again.
Knife I need will always be less than the knife I want. But if I was the kind of guy who was happy to do all my camping with whatever I got at the big box store, and wondered why it was so hard to cut things, I wouldn't be here, talking to you.
