To be perfectly honest, if I was only allowed to take the proper clothes for the season and one other object, that object would not be a knife. I'd rather have a compass
Ok I am using Elen's message to make one of my points. Nothing personal Elen as your post is one of the better ones .
Proper clothes for the season is sensible but seriously are the clothes going to be enough for survival overnight ? I wouldn't be traveling at night in the dark in unknown country. I would need two snowmobile suits for sleeping outside at -4C assuming I made a bed of dryish material.
In that area of Ontario at this time of year it often gets down to freezing at night. In fact I just checked the weather forecast in that area for the next three days. Tonight it is going down to -4C or 25F , tomorrow will be sunny then the next day has a good chance of showers.
In the boreal forest you don't need a knife to gather wood, YOU USE STANDING DEAD WOOD that you pick , break off and push over by hand an axe helps but the kidnappers took that away from you
The only thing the knife is for is making a fire by friction kit.
