Northern, another Canuk here although I admit that most of my time is an urban environment. I EDC regularly a SAK-OHT. When I'm playing in the snow, as a minimum I have the same SAK-OHT plus a fixed blade. Personally, I think you are wanting in the fire department, especially this time of year, with nothing but a pocket fixed blade.
Yes, you can process bigger wood with it, but not efficiently. If you had to bed down for the night in that fluffy stuff, that little fire in your OP won't cut it, nor will it last an hour without constant replenishing. Its great for making a cuppa, warming the hands but not a real way to process woods. Truly, my SAK-OHT while capable of processing wood faster is also insufficient to provide longer term fire/warmth. I think you really should consider a take-down buck saw as part of your combo or a 3/4 axe.
But hey, you did have 'For Real' in your title. If was 'for play', then a 3" pocket fixed blade is more than enough.
Though I personally feel that since a reasonable fire can be started this Also means I could get a large fire started for the sake of a overnighter you are right I do generally take an a e or hatchet with me. I agree completely. Although. Based on current inventory this would be the one knife for me that I own.
