I think a lot of the draw to ferro rods is because they're also more waterproof than the other options.Bic lighter... OK you don't have that for some reason, waterproof matches... OK you don't have that for some reason... why are you making this so hard on yourself? :-) A ferro rod... though why you would have that and not a bic or matches is beyond me.
Also make sure you have the biggest knife you can find. It needs a 15" long blade made of unobtanium and weight at least 5lbs. Anything else will get you killed!
Sorry for being a bit cheeky, but I feel like people way overthink "survival" stuff. Having worked S.A.R. in the Pacific Northwest, staying warm and dry is usually all you really need to worry about. Next is hydration. Don' trouble yourself with food. You will either be rescued or die from something else before you starve to death... unless you deliberately get lost in Alaska... again, why are you making this so hard on yourself?
