Well, I still pick the Gerber 800 multi-tool instead of the Wave, but since they're both multi-tols, I'm not *really* cheating. But I prefer the Gerber over any of the other multi-tools out there, and a multi-tool is way more versatile than an SAK Rucksack.
For the actual knife, I'd choose my Glock M78 Field Knife. And since we have the option of a mini-kit, I'll go with the kit that I actually have attached to my Glock's sheath in a compass pouch. I've got your basic Altoids tin kit, plus a wire saw and piece of hacksaw blade, since the Glock is only a so-so choper. Give me a canteen and cup, and I'll be happy. And maybe a poncho and liner for that little bit of "luxury". :~}
