Navigating knife laws in New York can be challenging due to a mix of state statutes and stricter local ordinances, especially in New York City. This guide provides an up-to-date overview of your knife rights and responsibilities in 2025.
Are Knives Legal in New York?
Yes, knives are generally legal to own and carry in New York, but there are strict regulations on the types, blade length, and how you carry them. Both state law and local ordinances, particularly in NYC, play a role in determining what is permissible.
Types of Legal and Illegal Knives
Legal Knives
Folding knives (with blades under four inches, especially in NYC)
Utility knives and work-related blades
Chef’s knives for culinary purposes
Illegal Knives (Statewide)
Switchblades
Ballistic knives
Cane swords
Metal knuckle knives
Pilum ballistic knives
Stilettos (with blades over four inches)
Gravity knives (banned in NYC, though state law has relaxed restrictions)
Blade Length and Carry Restrictions
| Location | Blade Length Limit | Visibility Rules | Notes |
|---|---|---|---|
| New York State | No explicit limit | Concealed or open, intent matters | Illegal if intent to use unlawfully |
| New York City | 4 inches | Must be fully concealed; not visible | Applies to all knives, including utility |
NYC strictly enforces a four-inch blade limit for any knife carried in public, whether open or concealed. Even a visible pocket clip can be a violation.
Statewide, there is no explicit blade length restriction, but intent and context (such as carrying for self-defense) can make even a legal knife illegal.
Intent and Use
Intent matters: Carrying a knife for self-defense or with the intent to use it as a weapon is illegal, regardless of blade length or type.
Lawful purposes: Carrying a knife for work, recreation, or culinary use is generally legal, provided you comply with local restrictions and do not display the knife in public.
Restricted Locations
You cannot carry knives in:
Schools: All knives are banned on school grounds, including public, private, and charter schools.
Government buildings: Most prohibit any knives.
Public transportation hubs: NYC bans all knives in the subway and other transit systems.
Age and Other Restrictions
Minimum age: You must be at least 18 years old to legally possess a knife.
Criminal record: Individuals with certain criminal convictions or non-U.S. citizens may be prohibited from possessing knives.
Penalties for Violations
Possession of a prohibited knife: Can lead to criminal charges, fines, and possible jail time.
Carrying with unlawful intent: May result in misdemeanor or felony charges, with penalties up to one year in jail or more for repeat offenses.
Best Practices for Knife Owners
Keep blades under four inches if you are in NYC.
Always conceal your knife—no visible clips or handles.
Never carry a knife for self-defense; intent to use as a weapon is illegal.
Avoid restricted locations and check local ordinances before carrying.
Stay informed—laws can change, and local rules may be stricter than state law.
