Trolling? What a ludicrous statement to make and insulting to the OP. I don't see why people were wearing knives in public, if camping they could have put them in the day sack they had? I'd not worry about it if I'd been there but would have thought why the flip do these folk need to carry knives, it just seems pointless. Just my opinion and I'm certainly not trolling, just expressing my view as did the OP.
Agree. And cbr6fs' post also summed it up pretty well. Perhaps everyone needs to look at the cartoon above again. There's a lot of group 'individual' ideas being expressed.
I've said it before and I'll say it again, as long as what you are doing is legal, then go ahead; HOWEVER, we do not live in a vacuum and you may also wish to think about how our/my hobby is perceived by the general public. I would rather bushcraft be seen as a more holistic subject, involving shelters, food, craft, clothing, cooking, etc, many of which require a knife or axe. Sadly, the focus seems to be on the sharps rather than much else - look at the numbers of posts specifically on edged tools compared to other areas.
I think that is perhaps the point being made by the OP - that anyone wandering into the Bushcraft Show who didn't know much about the subject might be surprised - and perhaps put off - by the sight of a lot of people wandering around (unnecessarily, I would argue) with knives, regardless of their intent. You may feel it's 'their loss', I feel it's 'our loss' as a Community. Because, regardless of whether I agree or disagree with others on this forum and on the ground, we are still a community, aren't we?
If you genuinely believe you need to have it with you or worry about leaving it in your tent/shelter, you could always put it in your day sack (as suggested above) or wear it round your neck and under your jacket/shirt. No-one is less of a man (or a woman) for this.
And, as for 'trolling'? I don't think so...
