Hertfordshire Constabulary will hold a month-long amnesty throughout July, encouraging residents to surrender certain types of "ninja swords" ahead of new national legislation banning their ownership.

The initiative runs from Tuesday, 1 July to Wednesday, 31 July, as part of a government-backed scheme designed to remove potentially dangerous weapons from homes before the law changes on 1 August 2025.

The incoming legislation will make it illegal to own swords that meet specific design features. According to the government's criteria, banned items include straight-bladed swords measuring between 14 and 24 inches, featuring a primary and secondary straight cutting edge with a blunt spine.

In preparation for the ban, the government has launched a surrender and compensation scheme, allowing current owners to hand in qualifying weapons safely and legally. Eligible individuals will receive financial compensation in return.

Swords can be surrendered at Hatfield, Stevenage, and Watford police stations throughout the amnesty period. Full station addresses and opening times are available at www.herts.police.uk/stations.

Chief Superintendent Nev Hanks, who is leading the local campaign, urged residents to take advantage of the amnesty.

"The amnesty is a chance for anyone in possession of this type of weapon to surrender it legally and safely," he said. "Once the new legislation comes into force, police will be able to seize any such weapons they find and prosecute the owner. Possession of banned weapons—even if just in a drawer at home—can mean a prison sentence of more than four years."

He added: "The criteria set out in the new law is quite specific. If you think a sword you own might be affected, please visit Gov.uk for full details."
