I'm visiting Scotland in September and was wondering the do's and don'ts of sgian dubh wearing. I'd like to respect tradition and wear one, but not sure of the legality of carrying a blade in the UK.

I have a decent, if a little dressy one, and a dreadful "safety" model that came with a package years ago. A sgian brew seems like a good alternative, but haven't got one of those. Definitely know to pack anything pointy in checked luggage.

Advice?
