Ian, unless you want to carry one of the new kids vicrtorinox knives, with a blunt tip, and not much of an edge, or better yet one of the victorinox plastic swiss army knives, they are going to find something wrong with most everything you can think of. They may even find something wrong with those too!
Now, you could try an ag russell pen knife, or a victorinox cadet, those are pretty unobtrusive.
Unfortunately some people can be real "hypochondriacs". I know many people like this over the years, from living in different places. The south is much more forgiving, than people in the north. Most ural areas, no matter where they are, like my grandfathers old Illinois farm in the 70's, places like that, knives are tools. People think no differently than that. Just like kids back then (70's) could take their rifles to school during deer season, leave them in the lockers, go to deer camp after school was over.
We carried our pocket knives to school, wherever we went. I was given my first knife at the age of four. No thought was ever given to fear. People tend to watch too many movies these days, and do not live in reality much. They seem to breed fear in the newspapers, internet, etc.
There's allot of factors out there that play into this.
I imagine a buck 110, or 112, will still upset some people.
If I were you, I would not worry about pleasing others, just use good wisdom when you carry different knives in different places. And remember, there are those that will find something wrong with anything. Just use good judgement. And enjoy your knives!
I grew up in a differen time, and it is past. We all have to adjust somewhat, but it doesnt mean we have to give up what we enjoy.
try the ag russeell pen knife, or victorinox cadet. if that offends people? There's not much you can do at that point!
