In Cliff's original post, this was a survival situation. Whether it be plane wreck, day hike gone bad, or whatever.
The point of these discussions is that something has taken a drastic turn for the worst, and we may not have all the material and gear with us, that we would like.
Day hikers wouldn't be carrying a sleeping bag, and even [gasp] when your plane went down you didn't have your paracord with you.
I srtuggle sometimes, and keep reminding myself not to become too reliant on one single peice of gear, or make the assumption I will always have all of my kit. I allow myself to assume i will at least have a pocketknife as I carry it 99% of the time. If I have my car keys, then I have a small multi-tool too.
In Cliff's case, without him getting very detailed I imagined a light plane having to ditch in the wilderness, someone with extremely bad sight and/or darkness, limited gear, and having to build a shelter.
Blindness, wow, lets hope that none of us have to "go there".
Nightfall, cloudy night, tough to see. Easily believable.
Assume a decent knife and a bic lighter, or a magnesium and flint.
Assume there had been a recent rainfall, so dry kindling has to be foraged, not just there for the picking. No flashlight.
What do you do?
I am thinking that I am gonig to do my best to get my natural nightvision working, then carefully check my surroundings. First a 10 foot perimeter, then a little more. get hold of a good length stick, to act as a walking stick and poker. use it as a probe in the dark to make sure you don't walk off of KevinTheGrey's cliff edge. If you or your pilot have the Bic lighter, you have some good fortune, because they make nice little intermittant flashlites.
Carefully shave some bark for tinder. Get a fire going.
Now you have some light in your area. Is there more wood close-by?
Is it a good area to make camp? Yes and yes.
Gather enough wood to secure the fire as stable, if wood is wet, stack it near the fire so you always have some drying. Use plane fuel to dry wood an make a nice toasty bright fire.
Proceed to shelter build. No paracord. No tarp material. Fair assumption.
Find a sapling, other materials for the debris shelter.
And so on.
Again, I try my best to handycap my thought-up situation, as Cliff did, in order to account for dealing with the lack of material you may otherwise have for a planned outing.
If any of us were day hiking, We'd have our kit, blades, firestarting material, paracord, and hopefully our health. Getting stuck or lost while on a day hike would be one of the easier scenarios, as when we hike, we typically have a good deal of our "wilderness" kit with us.
It's those unforeseen events, Car goes off road, down into ravine late at night. Small plane ditches. Small boat loses motor function, drifts for hours and finally runs aground in unfamliar area....those types of things are the more challenging scenarios.
Cliff, thanks for the example. The saw tool makes less noise, and is safer and easier to deal with in low light, as well as for "novice" use.
Cold, wet, tired and stranded + night time + hacking and slashing with a Big Blade can = severed artery, or massive fleshwound. Not a good way to start your survival ordeal.
Chalk one up for saws.
