I will be standing in for my brother to give my niece away at her wedding in a few months time. I live in Canada and she is in UK. I have been asked to dress with formality and with all the regalia. That would include a dirk and sgian dubh. I understand that there are restrictions in UK about the ownership and carrying of knives. I would like to bring mine and take them back with me out of the country. Before contacting the British authorities I was wondering if anyone else has experience doing this, or being banned from doing this. I will wade my way through the bureaucracy depending on the experiences of others.
