Ah, I see, I misunderstood your first post.
I think this is a very interesting in terms of what it means for martial artists. For example, plenty of Samurai swords are purchased at the martial arts expo 'Seni' (which, funnily enough, is in April), the event will be affected majorly.
Can you fiind the article?
Edit: no prob, I found it:
BBC NEWS | UK | Ban on imitation Samurai swords
It looks like the only way to aquire imitation swords will now only be through martial arts expo's like seni. Real samurai swords will still be allowed to be traded since they go for a vastly higher price than an imitation which you could pick up for £30. Martial arts clubs look to be unaffected:
"Ministers say they have recognised there is a special case for exemptions for genuine collectors of the original weapons and acknowledge there is a legitimate role for the blades in some forms of martial arts."
