First thing, congradulations for having the necessary focus to get out (though I would have to insert the obligatory "you should have told someone comment" even though I have been guilty of not doing it more than once).
Second, it is situations like these which come to mind whenever I see the carrot cutter crowd push the latest puukko as a survival knife. Yes the edge on the Camp Trap got slightly damaged by all the hacking and prying, consider how one of the ultra-light tomato slicers would have done in comparison.
This of course isn't an attack on such knives, I have many of them and they are great at what they are designed to do, performance in extreme survival/emergency situations isn't of course one of them. Greg Davenport is one of the few survival guys who makes a distinction between method of outdoor camping/living vs outdoor survival.
In a survial situation your main goal is to get out, when camping or living it is to create an adventure, a way of life or just to have fun. These enviroments are in no way similar. I can go to a junkyard and take pretty much any knife and carefully cut a hole in the roof, trunk or body of a car. If I take my time, use a decent baton and take care with hit placement the knife should come out ok, even with cheap knives, I have done it.
However if you are in a car, upside down, you may or may not be bleeding, the temperature is dropping, it is raining/snowing, your buddy may be worse still, there may be large predatory animals around attracted by all the blood and/or sounds of distress. All of these will greatly add to the stress and tension you are under, these tend to have more than slight effects on the ability to perform delicate tasks and a lot of caveman smash tends to happen.
There are times when you want a delicate slicer, and there are times when you want a solid blade. The worst that can happen if you need a delicate slicer and you have a solid blade is that your sandwitch is a little less than perfect, if you are hungry then you will not care, if you are not hungry then its not much of an emergency/survial situation - you just walk up out of you basement and presto you have "survived". If you need a solid blade and you have a delicate slicer, the worst than can happen is that you become someone else's sandwitch.
Hit that edge with a belt for a minute, I would not even bother to remove all the chips, just hone until the majority of the edge is sharp and she will be good to go. In time the edge damage will be removed with repeated honing. There are lots more truck removals left in that blade, of course you hope that she is never called on to have to do it, but you know that the ability is there if you need it.
