Is It Illegal to Carry a Knife in NYC? 2026 Laws

Yes, carrying many types of knives in New York City is illegal, and the rules are stricter than almost anywhere else in the United States. NYC has its own layer of knife restrictions on top of New York State law, which creates a legal minefield that catches residents and tourists alike.

Here’s what surprises most people: even a common folding knife can be illegal in NYC depending on how it opens and how long the blade is. Thousands of people have been arrested for knives that are perfectly legal in every other state.

This article breaks down exactly which knives are banned, what the blade length limit is, what happened to the gravity knife law, and what the penalties are for getting it wrong.

If you carry a knife in New York City for any reason, this is the guide you need for 2026.

Is It Illegal to Carry a Knife in NYC?

Carrying a knife in New York City is illegal if the knife falls into one of several prohibited categories, or if it is carried with intent to use it unlawfully against another person. Not all knives are banned, but the restrictions are significantly broader than in most US cities.

Two separate bodies of law govern knife carry in NYC. New York State Penal Law covers certain prohibited weapons statewide. New York City Administrative Code Section 10-133 adds a second layer that applies only within the five boroughs.

Together, these laws prohibit carrying knives with blades over 4 inches, most automatic knives, switchblades, stilettos, daggers, and any knife carried with unlawful intent. They also restrict displaying a knife in public in a way that causes alarm.

Here’s the practical reality: NYC enforcement of knife laws has been aggressive and controversial for decades. The NYPD made thousands of arrests annually under the old gravity knife law before its 2019 repeal. Carrying any knife in NYC carries real legal risk if you don’t know the rules.

• State law: NY Penal Law 265.01 covers criminal possession of a weapon in the fourth degree.
• City law: NYC Admin Code 10-133 adds blade length limits and display restrictions.
• Intent matters: A legal knife carried with intent to use unlawfully becomes a crime regardless of the knife’s type.

Is It Legal to Carry a Knife in NYC?

It is legal to carry certain knives in New York City, but the conditions are specific and the margin for error is small. A standard folding pocket knife with a blade under 4 inches that does not open automatically is generally legal to carry.

The key legal threshold under NYC Administrative Code Section 10-133 is a 4-inch blade. Knives with blades shorter than 4 inches are not automatically illegal under the city code (though state law and intent still apply). Knives with blades 4 inches or longer are prohibited for carry in public.

The city code also prohibits displaying or carrying a knife in a way that could reasonably cause another person to fear for their safety. This is a broad provision that gives police wide enforcement discretion.

The bottom line: a small folding knife with a blade under 4 inches is the safest choice for everyday carry in NYC. Anything larger, anything automatic, and anything perceived as threatening puts you in legal jeopardy.

NYC Knife Laws 2026

New York City’s knife laws in 2026 are governed by the same core statutes that have been in place for years, with the most significant recent change being the 2019 repeal of the gravity knife prohibition. No major new knife legislation was passed in 2025 that affects the rules going into 2026.

The two controlling legal authorities remain NYC Administrative Code Section 10-133 and New York State Penal Law Sections 265.01 and 265.02. Understanding both is essential, because a knife that passes muster under one law might still violate the other.

Key rules as of 2026:

• Blade length limit: Knives with blades 4 inches or longer are prohibited under NYC Admin Code 10-133.
• Automatic knives: Still prohibited under NY Penal Law 265.01.
• Gravity knives: Legal since the 2019 repeal of the prior prohibition.
• Display restriction: Displaying a knife publicly in a threatening or alarming manner is prohibited regardless of blade length.
• Intent provision: Any knife carried with intent to use unlawfully against a person is a crime.

The 2022 New York legislative session and the 2023 through 2025 sessions did not produce new knife-specific legislation for New York City. Enforcement practices, however, continue to evolve under NYPD discretion.

Bold fact: Between 2000 and 2019, the NYPD made an estimated 67,000 arrests for gravity knife possession, disproportionately targeting Black and Hispanic New Yorkers. The 2019 repeal was largely a response to that enforcement pattern.

What Knives Are Illegal in NYC?

Several categories of knives are explicitly illegal to carry in New York City under state and city law. Possession of these knives in public is a criminal offense regardless of intent.

Under New York State Penal Law Section 265.01, it is illegal to possess the following in a public place:

• Switchblades (knives that open automatically by button, spring, or lever)
• Stilettos (slender, pointed knives designed primarily for stabbing)
• Daggers (double-edged blades)
• Dirks (single-edged fighting knives)
• Ballistic knives (spring-propelled blade knives)
• Pilum ballistic knives
• Metal knuckle knives

Under NYC Administrative Code Section 10-133, it is additionally illegal to:

• Carry a knife with a blade 4 inches or longer in public
• Display any knife in public in a way that causes another person to feel threatened

Knives that fall into these prohibited categories cannot be legally carried in public regardless of who you are or why you have them, with very narrow exceptions for law enforcement and certain licensed professionals.

The distinction between a misdemeanor and a felony charge matters significantly. A Class A misdemeanor carries up to 1 year in jail. A Class D felony (for ballistic knives and certain aggravated weapons possession) carries up to 7 years in prison.

Key Takeaway: Switchblades, stilettos, daggers, dirks, ballistic knives, and any knife with a blade 4 inches or longer are illegal to carry in NYC. Even legal knives become criminal if carried with intent to use them unlawfully against another person.

What Size Knife Is Legal in NYC?

The legal blade length limit in New York City is under 4 inches. Knives with blades measuring 4 inches or more are prohibited for public carry under NYC Administrative Code Section 10-133.

This 4-inch rule is the city-specific restriction. It applies within the five boroughs, on top of whatever New York State law says. New York State law does not specify a universal blade length limit for ordinary folding knives, but NYC’s stricter city code fills that gap.

To put it in perspective: 4 inches is roughly the length from the tip of your index finger to the base of your palm. Most standard pocket knives have blades between 2.5 and 3.5 inches. Many tactical and hunting knives exceed 4 inches.

Measuring blade length matters legally. The measurement is taken from the tip of the blade to the point where the blade meets the handle, not including the handle itself.

• Under 4 inches: Potentially legal (subject to knife type and carry intent)
• Exactly 4 inches: Prohibited under the city code
• Over 4 inches: Prohibited under the city code

There is no minimum blade length below which all knives are automatically legal. A 3-inch switchblade is still illegal because it is a switchblade, regardless of blade length. The 4-inch rule adds a length-based restriction on top of type-based restrictions.

Practical tip: if you carry a folding knife in NYC for everyday tasks, keep the blade under 3.5 inches to stay comfortably within the legal limit with a margin to spare.

Knife Laws New York City

New York City knife laws come from two separate legal sources that operate simultaneously. City residents and visitors are subject to both, and violating either one creates criminal exposure.

The first source is New York State Penal Law. This applies everywhere in the state, including New York City. It prohibits specific knife types (switchblades, stilettos, daggers, dirks, ballistic knives) regardless of blade length. It also makes it illegal to possess any knife with intent to use it unlawfully against another person.

The second source is NYC Administrative Code Section 10-133. This is a city-specific ordinance. It adds the 4-inch blade length limit and the prohibition on publicly displaying a knife in a threatening manner.

Think of it like this: New York State law is the foundation, and NYC Admin Code 10-133 builds a second story on top of it. You have to clear both floors to be on solid legal ground.

The enforcement agency for both sets of laws is the NYPD. Police officers can charge someone under state law, city code, or both in the same incident. A single knife stop can produce multiple charges from different legal authorities.

• NY State Penal Law 265.01: Applies statewide; covers specific prohibited knife types and intent.
• NY State Penal Law 265.02: Aggravated weapons possession; applies when prior criminal record is involved.
• NYC Admin Code 10-133: Applies only in NYC; covers blade length and public display.

No New York State knife preemption law exists. Cities in New York are permitted to pass knife restrictions that are stricter than state law, and NYC has done exactly that.

New York State Knife Laws vs NYC Knife Laws

New York State knife laws and New York City knife laws are different, and both apply to anyone in the five boroughs. The city’s rules are significantly stricter than the state baseline.

At the state level, New York Penal Law focuses on specific prohibited knife types. A plain folding knife that isn’t a switchblade, stiletto, or dagger is not addressed by state law as an inherently illegal weapon. You could carry a large folding hunting knife in upstate New York without violating state law, assuming no unlawful intent.

In New York City, that same knife becomes illegal under the city code if its blade is 4 inches or longer. The city restricts blade length in a way that state law does not.

This difference has practical consequences. A hunter driving from Albany to New York City with a 5-inch hunting knife in their car may be legal under state law but in violation of NYC code if they carry the knife on their person in the city.

Tourists from other states face a particular risk. A 4.5-inch folding knife that is legal in every other jurisdiction might get them arrested in New York City. The city’s knife laws are stricter than the federal standard and stricter than most other major American cities.

Key Takeaway: New York City has a 4-inch blade length limit that does not exist under New York State law. Anyone in the five boroughs is subject to both state and city rules simultaneously, and the city rules are the stricter of the two.

Gravity Knife Law NYC

Gravity knives are now legal to own and carry in New York City following the 2019 repeal of the state law that banned them. This was one of the most significant knife law changes in New York history.

Before 2019, New York Penal Law Section 265.01(1)(a) prohibited possession of gravity knives. A gravity knife is one that opens by the force of gravity or centrifugal force when a button is released. The law was so broadly interpreted that many common folding knives could be opened by a “wrist flick” technique, which courts treated as gravity knife operation.

This led to mass arrests. Construction workers, electricians, and tradespeople who carried standard work knives were regularly charged under the gravity knife statute. Tens of thousands of people were prosecuted for possessing knives sold openly in hardware stores across the state.

In May 2019, Governor Andrew Cuomo signed Senate Bill S.1591-A, which removed gravity knives from the list of prohibited weapons under NY Penal Law 265.01. The repeal took effect immediately upon signing.

• Before 2019: Gravity knives illegal statewide; common folding knives frequently charged.
• After May 2019: Gravity knives legal throughout New York State, including NYC.
• Impact: Tens of thousands of prior convictions remain on record; expungement not automatic.

As of 2026, carrying a gravity knife in New York City is legal, subject to the same blade length and intent rules that apply to any other knife. A gravity knife with a blade under 4 inches and no unlawful intent is not a crime in NYC.

Folding Knife Laws NYC

Folding knives are generally legal to carry in New York City, but only if the blade is under 4 inches and the knife does not open automatically. These two conditions are what separate a legal everyday carry tool from a criminal offense.

A folding knife is one where the blade folds into the handle for storage. Standard pocket knives, Swiss Army knives, and most everyday carry (EDC) knives are folding knives. The distinction that matters in NYC is how the knife opens and how long the blade is.

If a folding knife opens manually, meaning you physically push the blade open with your finger without any spring or button mechanism, it is a standard folding knife under the law. If it opens with a spring-assisted mechanism that fully automates the opening, it may qualify as a switchblade, which is still prohibited.

• Manual folding knife, blade under 4″: Legal to carry in NYC.
• Manual folding knife, blade 4″ or over: Illegal under NYC Admin Code 10-133.
• Spring-assisted folding knife: Legal if manual force initiates opening (assisted opening, not automatic).
• Automatic/switchblade folding knife: Illegal under NY Penal Law 265.01.

The assisted-opening knife gray area is significant. Knives like the Kershaw SpeedSafe models use a torsion bar to help complete the opening after a human initiates it with manual pressure. These are generally considered legal because the opening is not fully automatic. Courts have distinguished these from true switchblades.

The practical rule is this: if the knife opens with a flick of a spring or button without any manual blade movement from you, it is an automatic knife and it is illegal in NYC.

Can You Carry a Pocket Knife in NYC?

Yes, you can carry a pocket knife in New York City if it has a blade under 4 inches and does not open automatically. A standard pocket knife used for everyday tasks is generally legal under both state and city law.

The term “pocket knife” usually refers to a small, manually operated folding knife. The classic single-blade folding knife with a 2.5 to 3.5-inch blade falls comfortably within legal limits in NYC. These knives are not prohibited by type under state law, and their blade length keeps them under the city’s 4-inch threshold.

Where people run into trouble is carrying a pocket knife in a way that attracts police attention. If you take out a legal pocket knife in a subway station and open it while arguing with someone, you’ve potentially crossed into unlawful display territory under the city code. The knife didn’t become illegal; the conduct did.

• Legal: Small folding pocket knife, blade under 4″, manual open, no threatening display.
• Illegal: Same knife if displayed in a threatening manner.
• Illegal: Same knife if carried with stated or demonstrated intent to use against someone.
• Illegal if blade 4″+: Even a plain pocket knife becomes illegal if the blade meets or exceeds 4 inches.

A good rule of thumb: if you’re carrying a pocket knife for a genuine everyday purpose like opening packages, cutting tape, or preparing food, you’re in the legal zone. The problem arises when the knife leaves the pocket in ways that suggest anything other than a mundane task.

Key Takeaway: Pocket knives with blades under 4 inches and manual opening mechanisms are legal in NYC, but how you carry and display the knife matters as much as the knife itself. Legal tools become criminal when used or displayed in threatening ways.

Can You Carry a Swiss Army Knife in NYC?

Yes, a Swiss Army knife is legal to carry in New York City. Swiss Army knives are small, manually operated multi-tools with blades well under the 4-inch legal limit. They are not prohibited under any NYC or state knife law provision.

The largest standard Swiss Army knife blade is typically around 3.5 inches or shorter. The most common models have blades between 1.5 and 2.5 inches. None of these come close to the 4-inch threshold under NYC Admin Code 10-133, and they are not switchblades, stilettos, daggers, or any other prohibited type under state law.

Swiss Army knives also include tools like scissors, screwdrivers, and bottle openers. These tools do not change the legal status of the knife as a whole. The legal analysis focuses on the blade component.

The one caveat is intent. A Swiss Army knife opened and displayed in a threatening manner is still subject to the city’s display prohibition under Admin Code 10-133. The knife type and size don’t immunize the carrier from the conduct-based restrictions.

For tourists visiting New York City and wondering if they can bring their everyday multi-tool, the answer is yes. A Swiss Army knife poses no legal issue under current 2026 law.

Kitchen Knife Laws NYC

Transporting kitchen knives in New York City is legal when done for a legitimate purpose, such as traveling to and from work or transporting them in a properly covered and secured manner. Carrying a kitchen knife openly on the street without a legitimate reason is where the law becomes problematic.

Kitchen knives present a specific challenge under NYC law because many have blades that exceed 4 inches. A standard chef’s knife typically has a blade between 8 and 10 inches. Under the strict reading of NYC Admin Code 10-133, carrying a kitchen knife with a blade over 4 inches in public could constitute a violation.

The key legal protection is purpose and context. A chef walking from their apartment to their restaurant with knives in a proper knife roll or case has a clear legitimate purpose. Courts and prosecutors apply common sense to these situations. The law is aimed at street weapons, not cooking equipment in transit.

• Legal: Transporting kitchen knives in a sealed case or roll to/from a workplace.
• Legal: Carrying a small paring knife (blade under 4″) for food preparation purposes.
• Problematic: Carrying a large chef’s knife openly on the street without a clear work context.
• Illegal: Any knife carried with unlawful intent, regardless of whether it’s a kitchen knife.

The practical standard is this: if you’re a food industry professional transporting your tools in a proper container, you’re in a defensible legal position. If you’re walking around the city with a 10-inch chef’s knife in your waistband, you’re going to have a very bad day.

NYC Knife Laws for Chefs

Chefs and food industry workers have a recognized practical need to carry professional knives in New York City. While there is no explicit statutory exemption written specifically for chefs in NYC knife law, the purpose and context of the carry provides legal protection in practice.

New York Penal Law Section 265.20 lists specific exemptions to weapons possession laws. These include law enforcement, military, and certain licensed professionals. Chefs are not specifically named, but the broader legal principle of lawful purpose and legitimate necessity has been applied by courts and prosecutors when evaluating knife possession by food service workers.

Before you go further, consider reading Is It Illegal to Have a Suppressor on Your Gun? 2026

The practical protection for chefs comes down to how the knives are transported and documented:

• Knives should be carried in a professional knife roll, knife bag, or protective case.
• The worker should be in transit between a home or residence and a workplace.
• Being in uniform, having work ID, or carrying restaurant documentation strengthens the lawful purpose defense.
• Knives should not be accessible or visible without opening the carrying case.

The risk increases significantly if a chef is carrying their knives off-route, in an unusual location, or in a manner inconsistent with work transit. A chef carrying a 10-inch chef’s knife in a backpack to a park on their day off does not have the same legal protection as one walking from their apartment to their restaurant at 9 AM.

Bold fact: NYPD officers are trained to evaluate context when encountering knife carriers. “I’m a chef going to work” is a commonly used and often accepted explanation for large knife transport, but it is not a guaranteed legal shield without supporting context.

Concealed Knife Laws NYC

New York City does not have a specific “concealed carry” permit system for knives the way some states have for firearms. The concept of “concealed carry” for knives is not the controlling legal framework in NYC. What matters is the knife type, blade length, and carry intent.

Under NYC law, a knife does not become illegal simply because it is concealed. A small folding knife carried in your pocket is concealed by nature, and that alone is not a crime. The illegality comes from the knife’s type, blade length, or the intent of the carrier.

That said, how a knife is carried can factor into how police assess the situation and whether charges are pursued. An officer who sees a person with a knife clipped visibly to their pocket might ask questions. One who discovers a large knife hidden in a waistband during a stop has more reason to suspect unlawful intent.

• Concealed small folding knife (blade under 4″): Generally legal.
• Concealed switchblade: Illegal regardless of concealment method.
• Concealed knife over 4″ blade: Illegal under city code regardless of concealment.
• Concealed knife with unlawful intent: Illegal under state law regardless of blade length.

The practical takeaway is that concealment is not the central legal issue in NYC. What you’re carrying and why you’re carrying it matter far more than whether it’s visible. A legal knife in a pocket is a legal knife in a pocket. An illegal knife in a hidden location is still an illegal knife.

Penalties for Carrying a Knife in NYC

Penalties for illegal knife carry in New York City range from a misdemeanor with up to one year in jail to a felony with up to seven years in prison, depending on the specific violation and the carrier’s criminal history.

The most common charge for knife violations in NYC is Criminal Possession of a Weapon in the Fourth Degree under New York Penal Law 265.01. This is a Class A misdemeanor. The penalties are:

• Up to 1 year in jail (Rikers Island or a similar facility)
• A fine of up to $1,000
• Probation as an alternative or in addition to jail time
• A permanent criminal record

If the person has a prior felony conviction and is found in possession of an illegal knife, they may face Criminal Possession of a Weapon in the Third Degree under Penal Law 265.02. This is a Class D violent felony. The penalties increase dramatically:

Beyond the immediate legal penalties, a weapons conviction in New York City carries collateral consequences. These include impacts on immigration status, employment background checks, housing applications, professional licensing, and eligibility for certain public benefits.

Key Takeaway: Carrying an illegal knife in NYC can result in up to 1 year in jail for a first offense, or up to 7 years in prison if a prior felony exists or if the knife is a ballistic weapon. The collateral consequences of a weapons conviction extend far beyond the immediate penalty.

What Happens If You Get Caught with a Knife in NYC?

If police catch you with an illegal knife in New York City, the typical sequence involves arrest, processing, arraignment in criminal court, and a formal charge under state or city law. The process moves fast in NYC’s court system.

During a street encounter, if an officer finds a knife on you, they will identify the knife’s type and blade length on the spot. If the knife is legal under both state and city law, you will typically be allowed to continue on your way, though the officer may confiscate the knife depending on the circumstances.

If the knife is illegal, here’s what happens:

1. Arrest: You are placed in handcuffs and transported to a local precinct.
2. Processing: Your personal information is recorded, and the knife is logged as evidence.
3. Arraignment: You appear before a judge, usually within 24 hours. Bail may be set.
4. Charge: You face a formal charge under NY Penal Law 265.01 or NYC Admin Code 10-133.
5. Prosecution: The Manhattan, Brooklyn, Queens, Bronx, or Staten Island District Attorney’s office handles the case.
6. Resolution: Cases may resolve through a plea deal, dismissal, or trial.

First-time offenders with no criminal history often receive an Adjournment in Contemplation of Dismissal (ACD). An ACD means the case is paused for six months. If you stay out of trouble, the charge is dismissed and the record is sealed. This outcome is common for minor knife violations in NYC.

Carrying a knife with any aggravating circumstance, such as using it in a threatening way, carrying it near a school, or having prior convictions, makes a favorable outcome significantly less likely.
