Chinese knife owners no longer anonymous

In a move aimed at reducing violence in the lead up to the coming world Olympics, China has decreed that citizens must register their identities when buying potentially dangerous knives. Probably a good idea, a simple scuffle can quickly escalate into a very bloody affair with the help of a knife. Not that only "dangerous" knives can cause serious injuries. Sadly, US citizens can only dream of this kind of law, as even firearms regulations in the states are lax. link
