NCGS 14-269 says, in part: "It shall be unlawful for any person willfully and intentionally to carry concealed about his person any bowie knife, dirk, dagger....razor...shuriken...or other deadly weapon of like kind, except when the person is on the person's own premises."
The NC Crimes Manual, printed for Magistrates & law enforcement says: "This offense does not apply to an ordinary pocket knife, carried in a closed position. An 'ordinary pocket knife' is defined as a small knife, designed for carrying in a pocket or purse, which has its cutting edge and point entirely enclosed by its handle and which may not be opened by throwing, explosive or spring action. Small has not been precisely defined by our appellate courts or legislature, but a pocket knife that was 4 1/2 inches in overall length was an ordinary pocket knife as defined by this statute. (96 NCApp 375).
