Herts Police are taking part in a week of action to combat knife crime.
Operation Sceptre, a national knife crime initiative, runs from Monday, November 16 to Sunday, November 22.
The force aims to highlight the dangers of carrying knives and prevent knife crime.
Superintendent Chris Hay, the force’s strategic lead for knife crime, said: "Knife crime remains low in Hertfordshire, but we are determined to keep it that way.
"We regularly support Sceptre alongside policing partners across the country, as part of our continuing effort to drive knife crime down even further.
"Knife crime is a priority for us throughout the year, but Sceptre gives us an opportunity to intensify that activity.
"We will be speaking to young people in schools and colleges about the risks of carrying a knife, working with retailers and giving people the opportunity to safely surrender weapons they should not have.
"Alongside that prevention work, there will be a strong enforcement focus.
"Our officers will be carrying out targeted activity across the county, using intelligence to identify and disrupt those we believe are carrying knives or are involved in violence.
"Where people choose to carry weapons or commit offences, we will take action.
"Carrying a knife does not make you safer and can have devastating consequences.
"We want to prevent people picking up a knife in the first place, but we will also continue to target those who choose to carry one."
During the week, officers will carry out targeted enforcement and knife-detection operations, and visit retailers to prevent illegal knife sales to under-18s.
Police will also visit schools and use social media to reach young people.
People can surrender unwanted or illegal knives at police stations in Hatfield, Stevenage or Watford during the campaign.
Permanent knife surrender bins, part of the Knife Angel initiative, are also available across the county.
People can anonymously surrender items including banned zombie knives, machetes and ninja swords in the bins.
