Is it against the law to own Katana swords surrounded by the UK?

I know it is illegal to sell or trade them, but what if you owned them beforehand the ban came into effect?
samuri and other curved blades over 50cm are prohibited, at hand are exceptions like genuine Japanese swords and other things. If you own a sword it is criminal to have it in a public place, so hold it at home and dont be a naughty boy, you will be fine. If you bought the sword before the restriction, then its exempt, it would only be banned if you took it too a public place.……
Most swords are illegal as they are classified as offensive missiles.
