Knife Crime: Things I Need to Know

Posted on:   Posted by:

Cardiff is usually a very safe city. However, it’s still important to raise awareness of knife crime for our own knowledge and safety.

Know the law around knife crime

It’s really important to know the law around knife crime – you may be breaking it without even realising it.

It’s illegal to:

  • Carry a knife in public without good reason, unless it has a folding blade with a cutting edge 3 inches long or less
  • Carry, buy or sell any type of banned knife
  • Use any knife in a threatening way (even a legal knife)

Any sharp instrument that is used in a threatening way (eg. a screwdriver) is also an offensive weapon.

Police officers have the right to stop and search any person or vehicle if they suspect an offence, including being in possession of an offensive weapon.

Most knives are banned and illegal to carry, however, some examples of good reasons to carry a knife in public can include:

  • Taking knives that you use at work to and from work
  • Taking knives to a gallery or museum to be exhibited
  • The knife is going to be used for theatre, film, television, historical re-enactment or religious purposes, eg. the kirpan some Sikhs carry

A court will decide if you’ve got a good reason to carry a knife if you’re charged with carrying it illegally. If you are unsure or worried about whether your knife is illegal, contact your local police to check.

Advice for students and young people

It is illegal to carry a knife even if it’s for your own protection. Police, teachers at school, and lecturers can search anyone suspected of carrying a knife.

By carrying a knife, you could get a criminal record or even a prison sentence. This will have an impact on future job prospects and whether you’re able to travel abroad to some countries.

Carrying a knife significantly increases the risk of you being injured. Your own knife can be used against you or someone may attack you in ‘self-defence’.

Using a knife, even in self-defence, can ruin your life and someone else’s. Even being there when someone else uses a knife can get you in trouble.

What should I do if I suspect someone of carrying a knife?

Keeping safe is the main priority. Immediately walk away if you are confronted with the threat of violence. Once in safety, tell somebody you trust – a parent, teacher, lecturer, friend or the police.

Remember to report anything you know about knife crime to the police on 101, or Crimestoppers anonymously at 0800 555111. You can also report anything to do with knife crime 100% anonymously via Fearless.

Knife Crime

What do I do if someone has been stabbed?

Although a stab wound usually causes a small opening in the skin, it may go very deep, causing serious damage to the body. You need to give first aid quickly if someone’s been stabbed as their lives could be at risk.

If you find yourself in a situation where someone has been stabbed you need to try and stay calm and follow these steps:

1. Call 999 for an ambulance.
2. Apply pressure directly over the wound to stem the bleeding (wear protective gloves if available)
3. If the knife (or any other object) is still in the wound, apply pressure on either side of the object. NEVER REMOVE IT FROM THE WOUND.
4. Help the casualty to lie down and elevate the bleeding area above the level of the heart to slow the bleeding.
5. Keep pressure on the wound until an ambulance arrives.
