Boy have we all got the hump today, must be the weather lol!
Seriously, I believe it should be personal choice about an EDC, if you feel the need go ahead. When I went for my Scout training (first three, you Scouters will know what that means) I was asked if I carried a folding knife and firesteel, it was a curiosity question, not part of the rules and regs, by the way. I said "no" and waffled a bit about knife law. My Training Advisor produced his from a pocket and asked me if mine would be any use at home if I needed them when I was out and about. I've carried a small SAK regularly since then, but I also carry my warrant card. I don't carry it into town and certainly not in the pub. It's just about using a bit of common sense really. Most Police officers are, in my experience, also endowed with common sense, and even if they were unsure of the law would probably only ask for the knife to check things out.
I also would like to disagree with an earlier post that suggesting one might find a reason to use a knife should one carry one (apologies I can't remember the exact wording), I feel that implies the argument that a knife may become misused as a weapon rather than what it is - a tool (apologies again if that posting did not mean that implication).
