On the theme of having a 15 year old thread, I think its interesting to look back at how I used to view the categories of knives over the past 15 years.
then: I didn't have a "camp" knife, just whatever knife I had with me, it meant a lot of time cleaning the knife to make sure that it stayed in my sheath, and didn't get misplaced. Now my "camp" knife is anything I can leave on the table preferably sheathed for safety, and does food prep pretty well. At the moment its a Mora2k, because the sheath is roomy enough to be cleaned, so the knife can go back in dirty, without to much worry. Another option would be a Vic paring knife with a clip-on edge guard.
Back then, a survival knife had to be big, beefy, preferably include a saw back, maybe a serrated section, be mean looking, and ultra everything. Camilus pilots knife to a SOG Seal Team elite (say that 10x fast) or SOG Pentagon elite2. But over time, other knifes started to make more sense, the value of other tools became clear, and now my "survival" If I could only have one knife is my Vic Rucksack. it just comes together for that tool. My view has also shifted well into the "Knife you have on you" camp. so that means finding knives I can carry, knives I can be familiar with, and then preforming the tasks I might need to do with that knife. Be it a Vic farmer, BR Mini-bushcrafter, mora 1, or RC-3. Each is a bit different, and will be useless to me if I don't focus on its strengths, and be mindful of its weaknesses.
Back when I was a kid there was one hunting knife and one only. A buck 119. all others were some sort of compromise, or gimmick. But I've come to realize that of all the things you can do with a knife, butchering is among the easier. Sure some designs make some parts easier than others, but if its getting meat off bones, or hide off the carcass, a sharp edge will do. Might not be pretty, but it will do. Making feather sticks with cold hands and a two pound blade that is half serrated, forcing you to use edge farther and farther from the fulcrum, well, that gets much more difficult, and could be far more dangerous than it needs to be.
So I guess over time the lines between have blurred far more, I used to think that a knife was designed for one purpose, now I realize that certain factors of a knife make it better or worse for certain things, but they are not hard and fast rules, and those compromises may not be as big a factor as I once thought. I've also realized that there is no magic in the design. Rather as the skill improves, the knife becomes less a factor in some ways, and yet the skills allow the knife to be more effective than it would be otherwise. I hope that makes sense.
