Well I didn't visit any so I didn't see any sheep.
I know that handguns are practically impossible to legally get in the UK but how about swords? I do know swords played a big role in the history and traditions of the UK so I would hope they aren't too regulated.
Your question intrigued me so I decided to do some "research"
You know what is amazing.... simple webfu....now I understand I am an IT guy so I know a little more than the average bear when it comes to things computer...so using a little know search engine called Google and using obscure terms like "are swords legal in the uk" I discovered in seconds that in 2008 there was legislation concerning any bladded weapon over 50cm (1 feet and 7.68504 inches)
New UK Sword Legislation - FAQ
We've just had the General Election, the government is fixed for the next five years more or less, no one campaigned about blades ( or guns) it's a non issue here, the right people have their swords and weapons, the wrong people get arrested. Try to bring bladed weapons here and I bet you won't even get to leave your own country, the airlines won't take you for a start.
If I understand the law correctly, and I admit I may not, if you had a bladed weapons collection prior to the law going into effect, you could keep it. Is that correct?
But walking down the street wearing your prize 1803 English Infantry Officers sabre or going down to the pub to show your friends your Scottish Claymore Long Swords was right out.
