North Carolina isn't a free as Tennessee...so don't cross the state line carrying a concealed knife.
"North Carolina law strictly controls the ability of individuals to carry weapons concealed. Except under the limited concealed handgun permit provisions of State law, described in Sections III. B. and III. C. of this publication, and the exemptions set out below, it is unlawful for any person in North Carolina, except when on his/her own premises, to willfully and intentionally carry concealed, either on or about his/her person, any “Bowie Knife, dirk, dagger, slungshot, loaded cane, metallic knuckles, razor, shurikin, stungun, or other deadly weapon of like kind.” Specifically exempted from the requirements of this law are ordinary pocket knives carried in a closed position. An ordinary pocket knife is defined as being “a small knife, that is designed to be carried in a pocket or purse, which has its cutting edge and point entirely enclosed by its handle. The knife must not be capable of being opened by a throwing, explosive, or spring action.” N.C. Gen. Stat. § 14-269. Whether, in a given case, a weapon is concealed from the public is a question of fact. By using the phrase “concealed about his or her person,” this law makes it illegal to have a weapon concealed not only on a person, but also within a person’s convenient control and easy reach."
