NYC Knife Laws 2026

Introduction

New York City has the most restrictive knife laws of any major city covered in this series — not because New York State law is unusually strict, but because NYC layers its own administrative code on top of state law, and the two don't always line up the way people expect.

For EDC users, fixed blade owners, and anyone visiting the city, this creates a genuinely confusing situation: a knife that's completely legal to own and carry under New York State law can still violate city rules the moment you carry it on a Manhattan sidewalk. Understanding NYC knife laws in 2026 means understanding both layers — what the state regulates through Penal Law Article 265, and what the city separately restricts through its own administrative code.

Understanding New York State Knife Laws

New York State knife law lives primarily in Penal Code Article 265, and it operates on two distinct tracks.

The first track is per se illegal possession under Penal Law § 265.01(1) — certain knife types are crimes to possess regardless of intent, location, or how they're carried. This category currently includes switchblade knives, pilum ballistic knives, metal knuckle knives, and cane swords, along with several non-knife weapons.

The second track is intent-based possession under § 265.01(2) — certain other items, including a dagger, dangerous knife, dirk, machete, razor, or stiletto, are only illegal to possess if carried with intent to use them unlawfully against another person. Ordinary possession of these items for lawful purposes — work, hunting, outdoor use — isn't itself a crime; the intent is what converts possession into an offense, and that intent can be inferred from the circumstances of how the item is carried.

A significant 2019 reform removed gravity knives from the first, per se illegal category — covered in detail below, since it's one of the most misunderstood parts of New York knife law.

NYC Knife Laws vs. New York State Laws

This is the section that catches the most people off guard. New York City doesn't just enforce state law — it layers its own restrictions on top through NYC Administrative Code § 10-133, and those city-level rules are often stricter and more frequently enforced than anything in the state Penal Law.

Two NYC-specific rules matter most: a blade-length restriction (any knife with a blade four inches or longer is illegal to carry in any public place, street, or park) and an open-view restriction (carrying or wearing any knife — any blade length — in open view in a public place is illegal unless actively being used for a lawful purpose). Neither of these rules exists at the state level. A 3-inch folder that's completely unrestricted under New York State law can still result in a summons in NYC if it's visible on a belt clip or carried without a qualifying lawful-use exception.

The practical takeaway: state law tells you what's illegal to possess anywhere in New York. City law tells you what's illegal to carry visibly or carry oversized specifically within the five boroughs. Both apply simultaneously inside NYC.

Legal Knives in NYC

Fixed Blade Knives

Fixed blade knives aren't categorically banned under either state or city law. A fixed blade is evaluated the same way any other knife is: it must avoid the state's per se illegal categories (it isn't one, as a category), it must stay under four inches and out of open public view to satisfy NYC's administrative code, and its possession can't reflect circumstances suggesting unlawful intent under § 265.01(2). Most fixed blades long enough to be practical for outdoor or utility use exceed the 4-inch NYC threshold, which is the main reason fixed blade carry is genuinely difficult to do compliantly within city limits.

Pocket Knives

Ordinary folding pocket knives are legal to own throughout New York State and within NYC, provided they don't fall into a prohibited category (not a switchblade, not a metal knuckle knife) and aren't possessed with unlawful intent. Within NYC specifically, a pocket knife also needs to stay under the 4-inch blade threshold and out of open view to avoid an Administrative Code § 10-133 violation — meaning even a fully compliant pocket knife needs to be carried fully concealed, with no exposed clip, hinge, or handle visible.

Illegal Knives in NYC

A specific set of knife types are illegal to possess under New York State Penal Law § 265.01(1), regardless of intent, blade length, or how they're carried. This includes switchblade knives, pilum ballistic knives, metal knuckle knives, and cane swords. Possession of any of these is criminal possession of a weapon in the fourth degree — a Class A misdemeanor — the moment you have one, independent of any NYC-specific rule.

Gravity Knives Explained

For decades, gravity knives were the most consequential — and most controversial — category in New York knife law. The statutory definition covers any knife with a blade released from the handle by gravity or centrifugal force that then locks into place. In practice, NYPD interpreted this definition broadly enough to cover ordinary folding knives that could be opened with a firm flick of the wrist, even when the knife wasn't designed or marketed as a gravity knife. This led to thousands of arrests annually of construction workers, tradespeople, and ordinary EDC carriers for possessing common folding knives purchased at hardware stores.

On May 30, 2019, New York State repealed the gravity knife ban, removing it from the § 265.01(1) per se illegal list. Mere possession of a gravity knife is no longer a state crime. That said, two important caveats remain. First, the NYC Transit Authority maintains its own separate ban on gravity knives within the subway and bus system, discussed below, so a gravity knife that's legal to possess on the street can still create exposure on the subway. Second, possessing any knife — including a gravity knife — under circumstances suggesting unlawful intent can still trigger a charge under § 265.01(2), and within NYC, a gravity knife still has to clear the 4-inch and open-view rules like any other knife.

Switchblades

Unlike gravity knives, switchblades were not part of the 2019 reform. A switchblade — defined as any knife with a blade that opens automatically through hand pressure on a button, spring, or similar device — remains squarely on the § 265.01(1) per se illegal list. Possessing a switchblade anywhere in New York State, including NYC, is criminal possession of a weapon in the fourth degree regardless of intent or how it's carried.

Open Carry vs. Concealed Carry

New York State law doesn't generally distinguish between open and concealed knife carry the way some other states do — its focus is on knife type and intent, not visibility.

NYC flips this entirely. Under Administrative Code § 10-133, visibility is the central issue: carrying or wearing any knife in open view in a public place is itself illegal, regardless of blade length, unless the knife is actively being used for a lawful purpose at that moment or a specific exemption applies. This means a knife that's completely legal in every other respect — under four inches, not a prohibited type, no unlawful intent — can still generate a summons in NYC purely because a clip, hinge, or handle was visible. In practice, this makes concealed carry the only realistic compliant option for knife owners in the city, the inverse of how visibility works in most other jurisdictions covered in this series.

Knife Length Restrictions

NYC Administrative Code § 10-133 sets a hard threshold: any knife with a blade of four inches or longer is illegal to carry in any public place, street, or park within the five boroughs, regardless of whether the knife is concealed or visible. This rule has no equivalent at the New York State level — state law doesn't impose a blanket blade-length limit, and outside NYC, blade length alone generally isn't determinative of legality.

Blade length is typically measured from the tip to the point where the blade meets the handle. This means a knife that reads as compact in overall size can still exceed the threshold if it has a long, thin blade — it's worth measuring the actual cutting edge rather than estimating from the closed knife's overall length.

Knives on Public Transportation

The NYC Transit Authority maintains its own restriction, separate from both state Penal Law and the city's Administrative Code, found in transit regulations covering the entire subway and bus system. Weapons and dangerous instruments — explicitly including switchblades, box cutters, straight razors, gravity knives, and swords — are prohibited anywhere within the NYC Transit System, including stations, platforms, and vehicles.

This creates a layered compliance problem worth understanding clearly: a gravity knife that's fully legal to possess on a New York City street under the 2019 state reform becomes a transit violation the moment you carry it into a subway station. The same applies to other items, like certain pocket knives, that might otherwise clear state and even city rules but still fall under the transit system's broader weapons restriction. Transit police enforce this independently of NYPD street enforcement.

Knives in Government Buildings

Federal buildings within New York City — including federal courthouses, federal office buildings, and other federal facilities — are governed by federal law rather than state or city law. Under 18 U.S.C. § 930, possessing a dangerous weapon in a federal facility is a crime, but the statute specifically excludes a pocket knife with a blade under 2.5 inches from the definition of "dangerous weapon." Federal court facilities are treated even more strictly than ordinary federal buildings, with security screening typically enforcing this threshold directly at the entrance.

New York State and city government buildings — courthouses, municipal offices — generally rely on building-specific security policies and screening rather than a single statutory blade-length threshold, but in practice, any visible knife is likely to be confiscated or questioned at security regardless of whether it would otherwise be compliant on the street.

Carrying Knives for Work

Both the per se illegal categories under state law and NYC's Administrative Code restrictions include narrow exemptions for people who carry a knife as a customary part of their work. Administrative Code § 10-133 specifically exempts people in military service when duly authorized, police and peace officers, participants in special events authorized by the police commissioner, members of the U.S. military or federal service performing official duties, and emergency medical technicians or ambulance drivers while performing their duties.

Beyond these named categories, the practical reality for tradespeople and others who carry a knife for legitimate work purposes is that the lawful-use exception in § 10-133(c) — actively using the knife for a lawful purpose — can cover a knife being used in the course of a job, but doesn't necessarily protect a knife simply being carried to or from a job site if it's visible or oversized. The safer approach for a knife required for work is to transport it concealed, ideally in a sealed container or bag, rather than relying on an implied work exception while it's not actively in use.

Can Tourists Carry Knives in NYC?

Yes, under exactly the same rules that apply to residents. There's no special exception or relaxed standard for visitors — a tourist carrying a knife that violates the 4-inch rule, the open-view rule, or possesses a per se illegal type is subject to the same enforcement as anyone else. Visitors from states with more permissive knife laws should treat NYC's rules as the binding standard during their stay, since a knife being legal at home offers no protection here.

Penalties

Penalties differ significantly depending on which layer of law is violated.

A violation of Penal Law § 265.01 — possessing a per se illegal knife (switchblade, pilum ballistic knife, metal knuckle knife, cane sword) or possessing any knife with unlawful intent — is criminal possession of a weapon in the fourth degree, a Class A misdemeanor carrying up to 364 days in jail and a permanent criminal record.

A violation of NYC Administrative Code § 10-133 — the 4-inch blade rule or the open-view rule — is a lesser, violation-level offense, punishable by a fine of up to $300, up to 15 days in jail, or both. It's not a misdemeanor and doesn't carry the same criminal-record consequences as a Penal Law conviction, but it still results in an arrest or summons and a required court appearance.

Quick Reference Table

FAQ

Are gravity knives legal in NYC?

Yes, as of the May 30, 2019 state reform, mere possession of a gravity knife is no longer a crime under New York Penal Law. However, gravity knives remain banned within the NYC Transit System under separate transit regulations, and any gravity knife carried in NYC still has to satisfy the city's 4-inch and open-view rules like any other knife.

Are switchblades legal in New York?

No. Switchblades were not affected by the 2019 gravity knife reform and remain illegal to possess under Penal Law § 265.01(1), regardless of intent, blade length, or how they're carried, anywhere in New York State including NYC.

What is the legal knife blade length in NYC?

NYC Administrative Code § 10-133 prohibits carrying any knife with a blade of four inches or longer in any public place, street, or park, regardless of concealment. New York State itself doesn't impose a blanket blade-length limit outside the city.

Can I carry a pocket knife openly in NYC?

No. NYC's open-view rule makes it illegal to carry or wear any knife visibly in public — including a clip, hinge, or handle showing — unless you're actively using it for a lawful purpose or a specific exemption applies. Full concealment is the practical requirement for compliant carry in the city.

Can I carry a knife on the NYC subway?

Generally no, regardless of what's legal on the street. The NYC Transit Authority separately prohibits weapons and dangerous instruments — including knives, box cutters, and razors — anywhere within the transit system, enforced independently of street-level NYPD enforcement.

Can I carry a fixed blade knife in NYC?

Only if it stays under the 4-inch blade threshold and is fully concealed from public view. Most fixed blades long enough for practical outdoor or utility use exceed that threshold, which makes compliant fixed blade carry within the city genuinely difficult.

Can tourists carry knives in NYC?

Yes, under the same rules that apply to residents. There's no relaxed standard for visitors — a knife that's legal in your home state offers no protection under NYC's Administrative Code or New York State Penal Law once you're in the city.

What's the difference between New York State and NYC knife law?

State law focuses on specific prohibited knife types (switchblades, metal knuckle knives) and unlawful intent. NYC layers two additional rules on top — a 4-inch blade limit and a ban on carrying any knife in open public view — that don't exist anywhere in state law and apply only within the five boroughs.

Can I bring a knife into a federal building in NYC?

Under 18 U.S.C. § 930, a federal facility generally prohibits dangerous weapons, but specifically excludes a pocket knife with a blade under 2.5 inches from that definition. Federal court facilities enforce this strictly through security screening.

Can I carry a knife for work in NYC?

Specific exemptions under Administrative Code § 10-133 cover certain occupations, including EMTs and ambulance drivers performing duties, along with military and law enforcement personnel. For most tradespeople, the safer approach is transporting a work knife fully concealed rather than relying on an implied work exception while it's not actively in use.

Note on currency: New York knife law has two active layers that can each change independently — state Penal Law and NYC's Administrative Code — and enforcement practices have shifted meaningfully even when the underlying statutes haven't (as seen with the 2019 gravity knife reform following years of contested enforcement). Readers should verify current statutory language directly through the New York State Senate's official codes and the NYC Administrative Code before relying on any specific provision.
