Firm annotation
The elements are carrying a weapon (1) into a town, village or public way, either openly or without reasonable cause, or (2) into an assembly gathered for worship, festivity or any other purpose. Reasonable cause is the key filter, so carrying a tool or implement for a legitimate purpose may fall outside the offence, while carrying it openly or for no good reason in public is caught. As a petty weapons offence it is commonly charged together with, but is separate from, possession or carrying offences under the Firearms Act, which protect different interests, and it frequently accompanies more serious violent-crime charges arising from the same event.
Why this matters in practice
The maximum imprisonment is only ten days, so on its own this is a minor charge, but it is a frequent companion to firearms-act offences and to violent crimes such as assault, robbery or attempted homicide committed with the weapon. The central defence is reasonable cause for carrying the item, considering its nature and the circumstances. Because a knife, blade or firearm carried in public will usually trigger this section alongside heavier charges, the practical focus is normally on the more serious counts. Where firearms are involved, an accused should expect parallel liability under the Firearms Act as a distinct offence.
