South Carolina knife laws are among the most permissive in the country. No knife type is banned, there is no blade-length limit for general carry, and since March 2024 you can carry a knife concealed without a permit. The restrictions that remain are tied to specific locations, and a few of them carry felony-level consequences.
What You Can Own
State law does not prohibit possession of any specific type of knife. Switchblades, automatic knives, Bowie knives, daggers, dirks, stilettos, and fixed-blade knives of any size are all legal to own in South Carolina.
One federal boundary applies to how automatic knives move, not to whether you can have one. The Federal Switchblade Act restricts the interstate shipment and sale of switchblades, defined as knives with a blade that opens automatically by button, gravity, or inertia.1Office of the Law Revision Counsel. 15 USC 1241 – Definitions Common carriers like UPS or FedEx are exempt when handling those shipments in the ordinary course of business.2Office of the Law Revision Counsel. 15 USC Ch. 29 – Manufacture, Transportation, or Distribution of Switchblade Knives Possession of an automatic knife inside South Carolina remains lawful.
Open and Concealed Carry
South Carolina imposes no statewide blade-length restriction on carrying a knife. You can carry it on your belt, in a pocket, or in a bag.
Concealed carry changed in 2024. The prior statute, South Carolina Code Section 16-23-460, made it unlawful to carry certain weapons concealed on the person. That section was repealed by the South Carolina Constitutional Carry/Second Amendment Preservation Act of 2024.3South Carolina Legislature. South Carolina Code of Laws Title 16, Chapter 23 With that repeal, no general state law bars concealed carry of a knife, and no permit is required. Location restrictions still apply, and using a knife in a threatening manner brings separate criminal charges.
Where You Cannot Carry
K-12 School Property
Carrying a knife with a blade longer than two inches on elementary or secondary school property is a felony.4South Carolina Legislature. South Carolina Code 16-23-430 – Carrying Weapon on School Property The exceptions are narrow: law enforcement officers and people specifically authorized by school officials. Conviction carries a fine of up to $1,000, up to five years in prison, or both, and the knife can be confiscated.
A vehicle exception exists. You can have a knife in your car on school grounds if it stays inside a locked vehicle, secured in a closed glove compartment, console, trunk, or closed container in the luggage area.4South Carolina Legislature. South Carolina Code 16-23-430 – Carrying Weapon on School Property This statute applies only to K-12 schools. Colleges and universities are not covered by the felony provision, though individual campuses may have their own policies.
State House Grounds
It is unlawful to carry a firearm or dangerous weapon on the State House grounds in Columbia, meaning the area bounded by Gervais, Sumter, Pendleton, and Assembly streets, plus the Governor’s Mansion grounds. A knife that qualifies as a dangerous weapon falls within the prohibition. The offense is a misdemeanor punishable by a fine of up to $5,000, up to three years in prison, or both.5South Carolina Legislature. South Carolina Code of Laws Title 10, Chapter 11 – Section 10-11-360 A weapon can be kept locked in your vehicle if you are authorized to park on the grounds.
Federal Buildings
Federal facilities such as courthouses, post offices, and federal office buildings are governed by 18 U.S.C. § 930, which prohibits possessing a dangerous weapon inside. The statute specifically exempts pocket knives with blades shorter than 2½ inches.6Office of the Law Revision Counsel. 18 USC 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities A blade of 2½ inches or longer is treated as a dangerous weapon in these locations. Some individual facilities apply stricter screening than the statutory minimum.
Private Property
Private businesses can set their own rules. A property owner or manager can ask you to leave for carrying a knife. Violating a “no weapons” policy is not itself a crime in South Carolina; it becomes trespassing if you refuse to leave when asked.
Local Ordinances
South Carolina’s preemption statute stops cities and counties from regulating the transfer, ownership, possession, carrying, or transportation of firearms.7South Carolina Legislature. South Carolina Code of Laws Title 23, Chapter 31 – Section 23-31-510 That preemption covers firearms only and does not explicitly extend to knives. Local governments may have their own knife ordinances, and some municipalities reportedly restrict types such as switchblades. Checking the local rules is worth a few minutes before carrying an unusual knife in an unfamiliar city.
Penalties at a Glance

Why the School Property Rule Matters
The K-12 offense is a felony, and its consequences reach beyond the sentence. Under federal law, anyone convicted of a crime punishable by imprisonment for more than one year is prohibited from shipping, transporting, receiving, or possessing firearms or ammunition.9Bureau of Alcohol, Tobacco, Firearms and Explosives. Identify Prohibited Persons The school property offense carries up to five years, so it crosses that threshold. A felony conviction can also affect employment, professional licensing, and voting rights depending on the circumstances.
Traveling With a Knife
TSA prohibits knives in carry-on bags at airports. The exceptions are rounded-blade, blunt-edge knives without serrations, such as butter knives, and plastic cutlery. Knives can go in checked luggage if sheathed or securely wrapped to prevent injury to baggage handlers.10Transportation Security Administration. Sharp Objects
Amtrak lists knives as prohibited in carry-on baggage. Sheathed bladed tools may be transported in checked baggage on routes that offer checked service.11Amtrak. Prohibited Items in Baggage
Driving across state lines is its own consideration. Neighboring states may have stricter rules than South Carolina, so what is legal to carry concealed here can be an offense next door.
If You Are Stopped by Police
Carrying a knife legally does not shield you from being stopped or questioned. If an officer has reasonable suspicion of criminal activity, they can stop you and conduct a limited pat-down for weapons. A knife visible on your person or clipped to a pocket falls under the plain view doctrine, and an officer can observe and potentially seize it without a warrant if its presence suggests a legal violation.
Keep your hands visible. Tell the officer you have a knife before they find it. Do not reach for it. South Carolina’s knife laws are on your side in most situations, and handling the encounter calmly is what keeps a lawful carry from turning into something else.
