Goodness! After five pages, I hope we've found the answer. Since I got some time to kill, I'll add my .02 cents. If I could choose only one, it would be a multi-tool of a favorite flavor. If I could do two, it's the multi-tool and a Mora 510. I greatly appreciate the skilled survivalist and bush crafter who can build a primitive society in a few short weeks with just a Mora and a hatchet, knows all the best recipes for beetles, grubs, and homemade insect repellent, knows all the best bush shelters, and edible or medicinal plants. Over the years however, I have developed an even more profound appreciation for the bush pilots and boat operators who can fix a fuel line, loose wire connection, unplug an impeller, etc. and have us back at the cabin in time to crank up the oil heat, put a steak on the grill, and crawl into a soft bed with my latest hardcore adventure novel.
I've been weathered in a few times, and honestly every single blade I've had on me did just fine. I can recall one night we went places we shouldn't have on our snow machines. (That's Alaskan for "Snow mobile") We got stuck in a mountain blizzard and the only knife I had was a SAK Adventurer. I was able to cut boughs to keep us off the snow, build a barely functional wind break, and cut kindling for a small fire. I would have loved to have had a saw, axe, set of pruning shears, etc. but...the SAK did get me by....barely. I'm pretty sure if it had been more than a night I would have found and exceeded the limitations of that poor thing. We huddled in, ate some extra food I'd packed, and started the ten mile walk home thru calf high snow. With impeccable timing, he troopers finally got a bird in the sky when we were about 1/4 mile from the road.
Of course, it's often really hard for us to relate to one another's perspectives. Somewhere out there, someone is not quite grasping mountain blizzards, just as I struggle to grasp a flash flood in the deserts or survival in the Everglades. I guess that's yet another factor that keeps it all interesting?
