Machete and zombie-style knife owners are being urged to surrender their weapons ahead of a government ban on owning them next month.
A nationwide scheme will be run at police stations across England and Wales for four weeks from August 26 to September 23.
People who hand over the potentially dangerous knives before it becomes illegal to own them on September 24 will not face repercussions.
After then, the weapons will be added to the list of dangerous prohibited items already banned – including butterfly knives, Samurai swords and push daggers.
Anyone caught with a zombie-style knife or a machete after this time faces time behind bars.
People can also dispose of the weapons using surrender bins by contacting their local police, council or an anti-knife crime charity.
Individuals are being encouraged to contact their designated police station first to get advice on how to package up any weapons and bring them into the station.
Policing Minister Dame Diana Johnson urged the public to ‘do the right thing’ to make streets safer.
