Q337: Is it illegal to carry a knife around in my pocket?
It is an offence to carry any sharp or bladed instrument in a public place, with the exception of a folding pocket knife, which has a blade that is 7.62 cm (3 inches) or less.
A lock knife is not a folding pocket knife and therefore it is an offence to carry around such a knife regardless of the length of the blade. A lock knife means a knife which is similar to a folding knife, in that there is a spring holding the blade closed. However, a lock knife has a mechanism which locks the blade in position when fully extended; the blade cannot be closed without that mechanism being released. A lock knife is not an offensive weapon per se (because these knives were made with a specific purpose in mind and not as a weapon). However, possession of a lock knife in a public place without good reason is an offence.
Possession of a multi-tool incorporating a prohibited blade/pointed article is capable of being an offence under this section even if there are other tools on the instrument which may be of use to a person in a public place (screwdriver, can opener). It is for the person to prove on the balance of probabilities that he/she had good reason for possession.
The penalty for committing this offence is a minimum prison sentence of six months, maximum four years and/or a fine.
Be aware that some bladed articles may be deemed to be offensive weapons, for example, flick knives, daggers and butterfly knives. There is also an offence of carrying an offensive weapon in public without lawful authority or reasonable excuse.Please see Q338 for further information.
