How to Talk to Your Child About Knife Crime: A Parent's Practical Conversation Guide
Nearly 48,000 knife offences were recorded in 2023/24. Talking to your child about the reality of knife crime — without scaremongering — is one of the most protective things a parent can do. Here is how.
Why this conversation matters
Young people aged 10–24 account for approximately 43% of all knife crime victims in England and Wales (ONS, 2024).[1] A trusted adult who can talk openly about risk is one of the strongest protective factors known to reduce youth violence involvement.
Why Parents Avoid the Conversation — And Why That's Risky
Many parents avoid talking to their children about knife crime for understandable reasons: they don't want to frighten them, they assume their child isn't at risk, or they don't know how to start. But silence carries its own risks. Young people who have not had honest, age-appropriate conversations about knife crime with a trusted adult are more likely to carry a knife themselves — often because they believe everyone else does and they need protection.[2]
Research from the Violence Reduction Unit (VRU) London confirms that young people who feel able to talk openly with parents about violence and danger are significantly less likely to become involved in knife crime, either as victims or perpetrators.
Age-by-Age Conversation Guide
Ages 8–11 (Primary)
Focus on safety rules rather than violence. Discuss why knives are dangerous tools, not toys. Establish the rule: "If you ever find a knife — don't touch it, move away, tell a trusted adult." Talk about peer pressure in age-appropriate terms: "If someone ever tries to make you do something that feels wrong, you can always say no and come to me."
Ages 11–14 (Early Secondary)
This is the highest-risk age for recruitment into carrying behaviour. Be direct but calm: "I know knife crime is something a lot of young people face. I want to talk about it with you — not to scare you, but so you know I'm here." Ask open questions: "Do any of your friends ever talk about knives?" Discuss the legal consequences (possession of a blade in public carries up to 4 years in prison) and the reality that carrying a knife increases — not reduces — the risk of being stabbed.
Ages 14–18 (Older Secondary)
Treat them as near-adults. Acknowledge the reality of the world they are navigating: "I know some areas feel unsafe, and I understand why some young people think carrying something makes them safer. I want you to understand why that logic actually makes things more dangerous." Discuss exit strategies for peer pressure, the specific legal risks (including losing the right to certain careers with a conviction), and agree a safety plan: a code word they can use in a text to you if they feel unsafe and need collecting without explanation.
What to Say If Your Child Tells You Something Serious
If your child discloses that they have seen a knife, know someone who carries one, or has been pressured to carry one themselves:
- Stay calm. Your reaction in this moment determines whether they keep talking. Thank them for telling you.
- Do not panic or immediately threaten punishment. This will shut the conversation down.
- Listen fully before responding. Ask open questions: "Can you tell me more about what happened?"
- Agree what happens next together where possible — this preserves trust.
- Contact the school's DSL (Designated Safeguarding Lead) — they are trained to handle this confidentially and without escalating unnecessarily.
- If there is an immediate threat to life — call 999.
The Law: What Your Child Needs to Know
Many young people genuinely do not know the legal consequences of knife possession. Make sure your child understands:
- It is illegal to carry a knife in public without a valid reason — even a penknife with a blade over 3 inches
- The maximum penalty for possessing a bladed article in public is 4 years in prison and/or an unlimited fine
- If convicted, this can affect university applications, employment (including in the NHS, teaching, and law), and the right to travel to countries like the USA
- "I carry it for protection" is not a legal defence
