People in Devon and Cornwall are being urged to hand over illegal or unwanted knives in a weapons amnesty being held by police.
Police hope the amnesty will cut the number of knives in circulation
It is part of a Home Office initiative to highlight dangers of having knives.
Secure bins are being set up at police stations where people can leave knives without fear of prosecution.
The force said although there were no significant knife crime issues in the region, the amnesty would allow people to dispose of unwanted weapons.
Officers believe this will reduce the number of illegal knives in circulation.
Police said people carrying knives might find the weapons turned against them during confrontations.
The amnesty is running until the end of June.
People taking knives to police stations should wrap them securely, using tape and cardboard before disposing of them.
Similar amnesties are being held by neighbouring Avon & Somerset and Dorset police.
