      The laws about knives and weapons

      Lesson details

      Learning outcome

      I can explain the law on knives and weapons.

      Key learning points

      1. It is illegal to carry a knife or offensive weapon without a reasonable excuse, even if you don’t intend to use it.
      2. The law covers a wide range of weapons, not just knives (for example, items that are disguised as everyday objects).
      3. Online sales of knives and weapons are regulated, but attempting to buy or sell illegally is also a crime.
      4. Weapon-related crime and possession carries serious consequences.

      Keywords

      • Offence - a breach of a law or rule; an illegal act

      • Possession - having something that belongs to you or is under your control, such as keeping an item, weapon or other object with you or in your care

      Common misconception

      If I carry a knife or weapon but don’t use it, I won’t get in trouble.

      Carrying a knife or weapon in public without lawful reason is a crime regardless of intent. Police can and do take action even if the knife or weapon isn’t used.

      Teacher tip

      Emphasise that laws are there to keep everyone safe. Be prepared to signpost pupils to support if they express concerns about their own safety or that of others.
