Here are his tips on knife safety:

• If you are confronted with a knife or somebody approaches you and you think there's a chance they could be carrying a knife, walk away
• DON'T think that you can talk to them and persuade them not to use it
• DON'T think that you can reason or negotiate with them, just walk away and tell an adult
• If you suspect that anyone you know is carrying a knife then it is important to tell a trusted adult, whether it be the police, a parent or a teacher
• It's illegal for anyone under 16 to carry a knife, so DON'T be tempted to carry one even if you think you need it to protect yourself
• If you're being bullied or are feeling threatened by people who you think may be carrying knives, DON'T be tempted to carry one yourself, just tell an adult your concerns about these people
• Most children who carry knives do it because they are scared. This is NOT a good option. If there are any people and places that scare you, it is best to avoid them completely
