Possessing a ninja sword is to be banned in the UK and carry a penalty of up to six months in jail, the British government said on Thursday, in a bid to curb what it has called a "national" knife crime "crisis".
The Home Office said most ninja swords had a blade of between 14 and 24 inches (36 and 61 centimetres), with one straight cutting edge and a tanto style -- or sharply-angled -- tip.
From August 1, anyone caught in possession of a ninja sword in private could face six months in prison. That is set to rise to two years under forthcoming legislation.
There is already a penalty of up to four years in prison for carrying any weapon in public.
The ninja sword ban is the final part of the so-called Ronan's law, a raft of anti-knife crime measures introduced in parliament last month as part of the government's crime and policing bill.
The measures include making retailers report bulk or suspicious sales to police and a rise in jail terms to two years for selling weapons to children.
