Knife crime ruins lives and devastates communities, yet it can be prevented. It is important for parents, guardians, and those who work with young people to understand the facts about knife crime, the law surrounding it, and strategies for addressing this issue.

This resource aims to provide an overview of this topic and support young people in making safer choices.

What the law says

The law is clear:

  • It is illegal to carry an offensive weapon like a knife in a public place without a “good reason”, even if you don’t intend to use it.
  • The maximum penalty for carrying a knife illegally is either four years in prison, an unlimited fine, or both.
  • A good reason for carrying a knife can include if it is a trade tool, for religious reasons, or a pen knife less than three inches long.
  • However, possessing a legal knife becomes illegal if it is used to cause injury or harm.
  • Police can stop and search anyone they believe is carrying a weapon.

You don’t have to just stab someone to have broken the law. Under ‘Joint Enterprise’ you could end up in prison for assisting or encouraging someone to commit a knife crime.

Facts about young people and knife crime

  • Although knife crime receives a lot of media coverage, only 1-in-1000 young people in Devon & Cornwall carry a knife (Devon & Cornwall Police data 2024)
  • There is no “safe” place to stab someone.
  • Many young people carry knives for self-defence or due to safety concerns.
  • Some young people carry knives because they’ve been pressured to do so, to gain credibility among peers, or to intimidate others.
  • By carrying a knife, you are more likely to get injured or stabbed yourself.
  • In some parts of the UK, you are statistically more likely to get stabbed by your own knife than someone else’s.
  • Many instances of knife crime are related to criminal activity like the drug trade. Criminal gangs may even exploit a young person to get involved in their activities, like so-called ‘County Lines’.
  • If you have a criminal record, you may not be able to visit other countries, like the United States.
  • BBC report: Knife crime has risen by 9% across the UK. Why are more youths carrying Knives

Signs a young person may be carrying a knife

Recognising signs that a young person may be carrying a knife is essential for early intervention. Some common signs include:

  • Changes in behaviour: Sudden or significant changes in behaviour, such as becoming withdrawn, aggressive, or secretive.
  • Changes in friendships and associations: If a young person starts associating with new friends and groups you haven’t heard of or met before.
  • Academic performance: A sudden drop in academic performance or engagement in school can also be an indicator.

However, it’s important not to jump to any conclusions even if you spot these signs. This pack includes a guide to speaking to a young person about knife crime that can help you broach the subject if you’re concerned.

The power of conversation

Relationships are critical in a young person’s decision to carry a knife. Talking with young people, especially those you care about, can make a big difference. Open and honest communication can:

  • Build trust: It helps build trust between you and a young person, making them more likely to confide in you.
  • Provide guidance: Conversations allow you to provide guidance, share information, and help a young person make informed choices.
  • Offer support: You can offer emotional support and reassurance that you’re there for them, even when they make mistakes.
  • Provide alternatives: Rather than scaring a young person about the dangers of knives, you are in an excellent position to suggest positive options and raise their self-esteem.

Remember that these conversations should be non-judgmental and focused on understanding the young person’s perspectives and concerns. Later in this resource, there is a more detailed guide to having conversations with young people about carrying a knife.
