We're not allowed to talk about that
Seriously though, I don't think comparing us to any other country has any merit at all; we are our history, we make legal decisions based on that.
That's fair enough, but gathering information on what works for a human population regardless of geographical location is still useful even if it doesn't work.
Ultimately our discussion here will not change a thing, Higher powers have decided this is the way and we have to deal with it as you we all well know. Unfortunately we live in a time where its considered too dangerous to be allowed to carry a "fixed bushcraft style" blade in public or certainly in the middle of a town. 300 years ago you'd probably be called mad for not carrying.
To answer the original question, I think it would be a good idea if we are talking about carrying and using illegal knives in public places. Whats important is the location the knives are intended being used in (which would need a lot of thrashing out) and for what purpose and being able to justify that purpose.
How that gets sorted out I haven't the faintest idea, but I reckon the Moral compass of the majority of members here would make it perfectly safe to have a sharp object in their possession and actually share the respect that should be given to and educate anyone interested.
However I wouldn't wear a knife on a belt sheath if i could avoid it. Society does actually make me feel ashamed to carry an illegal knife and that fact I have a mental illness make its a hundred times worse dreading anyone seeing me with one.
