I hate lugging around a toolbox into the backcountry. For most jobs, you just don't need a 15- to 20-pound chest of wrenches and ratchets and hammers and more for the woodsy fixes you need to get yourself back to civilization when things hit the fan. You do it, just because you'd rather be safe than sorry, but for the most part, it sucks.
For me, who likes to pack light, I want something that'll save me weight. Whether that's weight on my back when I'm out riding snowmobiles or dirt bikes, or saving weight when I'm driving an ATV or side-by-side, as I need that space for other gear like camping equipment or my hunting stuff. Tools, no matter how light your setup, tend to take up a bunch of space.
And for me, I want something like a multi-tool that is a jack-of-all-trades. It might be a master of none, but like the full saying goes, it's still better than a master of one. And very much still better than a master of one that weighs an additional 30 pounds.
