South Yorkshire Police have launched a knife surrender scheme in a 'zero tolerance' approach to the weapons on Sheffield's streets.
Under the scheme, anyone will be able to anonymously hand in a knife or bladed weapon between today and 11.59pm on Monday, July 31.
They will be exempt from prosecution over possessing the weapon, but police have said the knives will be forensically examined, which could lead to prosecutions if its proved they have been used for criminal activity.
Detective Superintendent Una Jennings, the force lead for armed criminality, said: “The aim of this campaign is to raise awareness of the grave and serious consequences that carrying a knife can have, whether it’s carried for ‘protection’ or ‘status’, the fact remains you have a lethal and dangerous weapon in your possession."
There are four locations where knives can be surrendered: Snig Hill in Sheffield, College Road in Doncaster, Churchfield in Barnsley and Main Street in Rotherham.
There will also be a knife bin on the police engagement bus today on Ellesmore Road, Burngreave, today between 3pm and 9pm.
“I would also urge anyone who may be in possession of knives or bladed weapons, such as daggers, swords, axes, that may have been passed down as family heirlooms and are no longer wanted, to please also make use of the surrender and hand them in," Det Supt Jennings said.
"To prevent them from falling into the wrong hands and being used in criminality.”
Police say the scheme is just one part of the campaign to put a stop to knife crime across the city.
Young men between 18 and 29 are the most likely to carry a weapon.
"A large proportion of the crime in South Yorkshire can be summed up in two words: Men fighting," Det Supt Jennings said.
"We want to demonstrate and offer assurance to the public that we do not and will not tolerate knife crime," Det Supt Jennings said.
"I hope this campaign, and wide range of activities and operations that will continue throughout the summer, highlights our commitment to tackle criminality and keep our county safe.”
A similar scheme took place last July, with 160 weapons handed in.
"Everything from kitchen knives to meat cleavers and a samurai sword," Det Supt Jennings said.
