A police force has stopped publishing images of knives seized in amnesties to avoid upsetting the public.
Photos of dozens of weapons laid out on tables by police are a common sight after successful knife amnesties.
But Thames Valley Police said it had stopped doing it because of the impact "knife imagery can have on those who see it".
The force is currently taking part in Operation Sceptre, a national campaign to reduce knife crime.
Its knife amnesty, which lasts until Sunday, involves members of the public anonymously dropping off weapons in special bins at 16 police stations across the region.
The force said it had made the decision to "stop publicising images of seized knives to help reduce the fear of knives and knife carrying in our local communities".
It came to the decision as a result of discussions held by the National Police Chiefs' Council and other forces.
A spokesperson added: "Although no formal guidance has been put in place, the force has decided that it will not publicise images of knives that have been seized throughout this week of action."
It has released a video on social media promoting Operation Sceptre, which depicts youths fighting but no knives.
Diana Fawcett, chief executive at independent charity Victim Support, welcomed Thames Valley's decision.
She said: "From our work supporting victims, witnesses and those bereaved by knife crime we know that one of their main fears around the trial is being faced with images of the weapon.
"Therefore being subjected to these images through the press and social media has the potential to re-traumatise victims and we support this decision not to publicise them."
