Knife Law Advice

We would like to try to clear a few things up about knife law in the UK as there still seems to be a lot of confusion out there. We are not professing to be any form of experts on the subject but we hope the information given on this page will help act as a useful guide.

Please note that this information is supplied for your information only and in all cases it is up to you to make up your own mind. You need to also take into account the changing face of Devolution in Britain and the laws may change depending on where you are in the UK. 

We are NOT Solicitors or Law Makers, so please follow the links at the bottom for more official information, or speak to a solicitor for legal advice. This information should not be relied upon in a court of law and you should always consult a Solicitor on legal matters, they are the experts in the Law and will be able to give you the best all round advice. Remember even if you believe yourself to be completely innocent of any crime you should, in all cases, consult a Solicitor.

We have some pretty sensible knife laws in the UK that allow you to use a knife for it’s intended purpose – REMEMBER it is a tool for doing a job and it has, and always will be an offense to use it as a weapon.
The law is quite clear but can be a little vague in places, whether this is intentional I am unsure but it is likely that it is to allow a sensible Policeman to use his discretion as there are no “Black and White” cases when it comes to the law.

The Criminal Justice Act (1988) says that you may carry a knife with a blade length of 3.0" or less so long as it is capable of folding and does not lock -  so no fixed blade knives as an EDC. This is for your “Every Day Carry” (commonly referred to as an EDC) or Pocket/Pen knife.
Remember, be sensible - There are exceptions to the EDC laws and you should fully research what they are but a knife has no place at a football match, in a pub, nightclub or school. This is not an exhaustive list and there are other areas of our lives that you shouldn't carry.

If you wish or need to carry a larger knife then you really need to have “Reasonable Cause”. That means that you must be able to prove that you had a genuine reason for carrying the knife. A “Reasonable Cause” can constitute a whole host of scenarios such as: These should all constitute a “Reasonable Cause” and you should not have any issues or dilemmas with the law - BUT don't forget it is there! If you stop off anywhere on your way home take the knife off of your belt and put it in the boot of your car. If on foot, be sensible, take it off your belt and put it at the bottom of your rucksack. These actions will demonstrate that you have made the tool as inaccessible as possible and not available in “The Heat of the Moment”. Ignorance is not a defence in law and you cannot simply say "I forgot".
REMEMBER – Do not give the Police a hard time, just follow instructions and if you feel you are correct in your actions seek advice from a Solicitor after the fact to argue your case. DO NOT stand there and argue with the Police as you will not win or convince them they are wrong.
