I hear you guys but for mebeing people friendly is one of the positive attributes a traditional has over a modern folder.
I can understand what You mean!
If You choose the proper tool for the job, I doubt You will get any comments or looks.
A traditional knife, fixed and/or folder is what I use in my work.
Sometimes I will need a bigger knife than a 3,5" pocketknife, sometimes I don't.
I adjust my choices for the day, to my needed work.
As I'm a carpenter, working with installing new kitchens in peoples homes, I'm supposed to have many tools.
The knives are just tools among other tools of the trade.
It's only Your own judgement, that can tell You what is the proper tool for Your kind of work, as there obviously aren't any general rules around to guide You.
Common sense is often the best way to follow.
If You like that #54 in Stag, get it!
If it's too big for Your needs, get a smaller version and use the #54 when camping or so.
For me those #42's aren't too big, but I can just as well take the smaller Northwoods Indian River Jack.
Why?
Well, one of my toolboxes has at least 5 Mora's to choose from.
