Knife Crime Defence
What is Knife Crime Defence?
Knife crime offences include carrying a bladed article or offensive weapon in a public place, threatening with a blade, and using a knife in the commission of another offence. They range from summary matters to serious Crown Court indictments, and custody is more common than people expect.
Custody is a realistic outcome for knife offences, particularly for threatening or for a second possession charge. The defences — lawful excuse, good reason, no knowledge of possession — turn on the specific facts. Early instruction allows the evidence that supports them to be gathered before it is lost.
Custody risk
Defences turn on what was found, where, and why.
Lawful excuse and good reason must be argued with evidence.
How a knife crime case proceeds
Most knife allegations begin with a stop and search. What you tell the police about why you had the item, and where you had it, is recorded at interview and becomes central to the case.
Simple possession can be dealt with at the Magistrates’ Court, while threatening with a blade or using one in another offence is sent to the Crown Court. The courts take a firm line, and custody is a realistic outcome even for possession, more so for a second offence.
How the defence is built
The first question is often whether the stop and search was lawful. Where it was not, there may be grounds to challenge how the item came to be found at all.
If possession is admitted, the law allows for a good reason or lawful authority — a blade needed for work, for example, or as part of a religious observance. Carrying something for self-protection is not a good reason. Whether a recognised reason applies turns on the precise facts at the moment of the stop.

Common questions
- I had the knife for work — is that a defence?
- It can be. Needing a blade for work is a recognised good reason, but it has to fit the facts: what the item was, why you had it at that moment, and where you were stopped. The same does not apply to carrying something for protection.
- I did not know the knife was there — can I still be convicted?
- Knowledge matters. If you genuinely did not know the item was on you or in your vehicle, that goes to the heart of the case, though it has to be supported by the circumstances.
- Will I go to prison for carrying a knife?
- Custody is a real possibility. The courts treat knife possession as a deterrent matter, and a second possession offence in particular carries a minimum custodial sentence in most cases. The circumstances and mitigation still matter.
- I am under 18 — does it work differently?
- Yes. A young person’s case is heard in the Youth Court under its own procedure, with reporting restrictions and a parent or guardian involved, and the approach to sentence is different from the adult courts.
