Knife Laws in Tennessee (2026): Surprisingly Few Rules to Follow

Most people assume Tennessee has all kinds of knife restrictions. Honestly, they’re wrong. Tennessee is one of the most knife-friendly states in the entire country. But a few key rules can still land you in serious trouble if you don’t know them.

Let’s break it all down simply and clearly.

What Are Knife Laws?

Knife laws are state rules that control what kinds of knives you can own, carry, and use. They also spell out where you can and cannot bring a knife. Some states have tons of restrictions. Tennessee keeps it simple. Pretty much.

The main Tennessee knife laws live in Tennessee Code Title 39, Chapter 17, Part 13. That’s the official legal home for weapons rules in the state.

What Knives Are Legal in Tennessee?

Here’s where things get interesting. Tennessee basically allows you to own every type of knife. No exceptions for blade type.

Tennessee permits ownership of every knife category. The state does not restrict possession or sale based on opening mechanism, blade design, or intended purpose. That means switchblades, butterfly knives, automatic knives, fixed blades, daggers, and assisted-opening knives are all fair game to own.

You’re gonna love this one. The 2014 repeal of the switchblade ban and 4-inch carry limit removed the last meaningful restrictions on knife carry. Before that, you couldn’t carry a blade over 4 inches. That rule is completely gone now.

So simple, right?

Can You Carry a Knife in Tennessee?

Yes. And with very few restrictions. This surprises a lot of people.

It is legal to own any type of knife in Tennessee including automatic, ballistic, switchblade, butterfly and assisted-opening knives. There are no restrictions on the blade length of any knife being carried. Further, Tennessee makes no distinction between open and concealed carry of knives.

Wondering if you need a permit? Nope. Unlike firearms, knives in Tennessee do not require a permit for concealed carry. You do not need to apply for permission, complete a training course, or notify any government body.

So you can carry a switchblade in your pocket. You can carry a fixed blade on your hip. You can keep it hidden or wear it openly. Tennessee doesn’t care either way.

That said, there are some important exceptions. Stay with me here.

Where You CANNOT Carry a Knife

Okay, pause. This part is important.

Tennessee has location-based restrictions. The biggest one is school property. Tennessee law restricts the possession and carry of weapons, including knives, on school property.

This covers a lot of ground. It is an offense for any person to possess or carry, whether openly or concealed, with the intent to go armed, any firearm, explosive, explosive weapon, bowie knife, hawk bill knife, ice pick, dagger, slingshot, leaded cane, switchblade knife, blackjack, knuckles or any other weapon of like kind in any public or private school building or bus, on any public or private school campus, grounds, recreation area, athletic field or any other property owned, operated, or while in use by any board of education, school, college or university.

That includes gyms, stadiums, and cafeterias. Not just the classroom.

Beyond schools, private parties and government entities can prohibit weapons on controlled property. Possession of a weapon on properly posted property is a Class B misdemeanor punishable by fine only. So if a business posts a sign banning weapons, you need to take it seriously.

The “Intent to Go Armed” Rule

Here’s where it gets interesting. Most people miss this part.

Tennessee doesn’t just care about what knife you carry. It also cares about WHY you’re carrying it.

Carrying a knife for utility, self-defense preparation, or hobby purposes is lawful. Carrying a knife with the specific intent to use it unlawfully against another person is a felony.

Think of it like this: your pocket knife for camping is totally legal. That same knife pulled out to threaten someone? That’s a serious crime. The knife doesn’t change. The intent does.

The “intent to go armed” with a knife or weapon is an element of the offense. It has been construed as requiring the prosecution to prove that the “intent and purpose in carrying the weapon was to be and go armed.”

So carrying a knife without criminal intent is always legal. Good to know.

What About Misleading or Hidden Knives?

Not all knives are treated the same way. Some are specifically off limits.

You’re never allowed to carry a misleading or undetectable knife while you’re in Tennessee. Misleading knives are knives that are designed to look like something else. Examples of this include knives concealed in a cane, a belt, or built into a lipstick tube. Undetectable knives are knives that are made out of material that doesn’t set off metal detectors.

Basically, if your knife is designed to trick people or bypass security systems, it’s not allowed. Makes sense, right?

Penalties: What Happens If You Break the Rules

Now, here’s where things get serious.

Let’s talk about school property first. This one hits hard. A violation of bringing a weapon onto school property is a Class E felony punishable by imprisonment for up to six years and a fine of up to $3,000.

That’s not a slap on the wrist. That’s a felony record. Up to six years behind bars. For carrying a knife onto school grounds.

And if you use a knife while committing a crime? A person commits an offense who possesses a deadly weapon other than a firearm with the intent to employ it during the commission of, attempt to commit, or escape from a dangerous offense. A violation of this subsection is a Class E felony punishable by imprisonment for up to six years and a fine of up to $3,000. The maximum fine may be doubled to $6,000 if the deadly weapon is a switchblade.

Wait, it gets worse for switchblades specifically. That doubled fine means you could owe $6,000. Think of it like a speeding ticket that suddenly turns into a car crash lawsuit. Much more serious.

Recent Law Changes: What’s New?

Tennessee has actually been loosening knife laws over the years. Not tightening them.

Knife Law Preemption was enacted in 2013, repealing dozens of local knife restrictions including those in the two largest cities in the state. In 2014, the state’s switchblade ban and 4-inch carry limit were repealed. Those were big changes that gave Tennesseans a lot more freedom.

More recently, Governor Lee signed Knife Rights-supported Senate Bill 1360 into law, effective July 1, 2025. This legislation extends existing firearm manufacturer liability protections to cover knives, saps, and other bladed or blunt-impact defensive weapons.

That’s actually a pro-knife-owner move. It shields manufacturers and sellers from being held responsible for how buyers use their products.

There was also a 2023 update worth knowing. Tennessee Governor Bill Lee signed legislation in 2023 that created a narrow exception to the prohibition on school grounds. Adults who are not students may carry a concealed pocket knife on school property when they are there solely to vote in an election. The knife must remain concealed and cannot be handled during voting.

So if your polling place is a school, you can bring your folding pocket knife. Just keep it put away the whole time.

Statewide Rules: No Local Surprises

Here’s something most people don’t realize. You don’t have to worry about different rules in Nashville versus Memphis versus Knoxville.

In 2013, Tennessee enacted knife law preemption under Tennessee Code Section 39-17-1314(f). This provision prevents cities, counties, and metropolitan governments from creating their own knife regulations. Before preemption, dozens of local knife restrictions existed across Tennessee. Nashville and Memphis, the two largest cities, both had their own rules. Preemption eliminated those local ordinances and blocked future attempts to create new ones.

One state. One set of rules. Pretty straightforward.

This is honestly one of the best parts of Tennessee’s approach to knife laws. You don’t have to research every city you visit.

Who Is Exempt From Knife Restrictions?

Some people don’t have to follow the school property rule. There are official exceptions.

Exemptions apply to persons employed in the army, air force, navy, coast guard or marine service of the United States or any member of the Tennessee national guard when in discharge of their duties. Law enforcement officers and school security personnel are also covered under the exemptions.

If you’re attending a gun or knife show approved by school officials, you’re also protected. Same if you’re driving through school property just to drop off or pick up someone, as long as the knife stays in your vehicle.

Most people won’t need these exceptions. But it’s good to know they exist.

How to Stay Legal in Tennessee

You’re not alone if this feels like a lot to take in. Most people don’t know these rules at all. Don’t worry, it’s actually simpler than it looks.

Here’s what you need to do:

First, you can carry almost any knife almost anywhere as a regular adult in Tennessee. No permit. No length limit. No blade-type restrictions.

Second, never bring a knife onto school property. That includes the parking lot, the gym, the athletic fields, everything connected to a school. This one rule trips people up the most.

Third, avoid knives designed to be hidden in everyday objects or built to dodge metal detectors. Those are off limits no matter where you are.

Fourth, if a building or business posts a sign banning weapons, leave your knife in the car. A misdemeanor is still a charge you don’t want on your record.

Fifth, use your knife legally. Carry it for work, camping, fishing, everyday use, or self-defense preparation. Never threaten anyone with it. Intent matters under Tennessee law.

That’s basically all you need to know.
