Calmac .. I always wear mine and have never had a problem. In fact, the time before last when we went to London to meet Hamish I was speaking to 2 Transport police at the station as they commented on my Cilt and they could clearly see I had my sgian dubh in my sock and they made no mention about it at all. I'm not saying its legal to wear it, I don't know, but as I say I have never had a problem and will continue to wear it.
