New York has some of the strictest and most complex knife laws in the United States, with significant differences between state law and local ordinances—especially in New York City. Here’s what you need to know about carrying pocket knives in New York as of 2025.
Statewide Laws on Pocket Knives
- General Possession: It is generally legal to own and carry pocket knives in New York State, provided they are not one of the specifically banned types (such as switchblades, ballistic knives, or metal knuckle knives).
- Age Restrictions: Persons under 16 years old may not possess a “dangerous knife” in New York.
- Intent Matters: Carrying any knife, including a pocket knife, with the intent to use it unlawfully against another person is a crime. Stating you carry a knife for self-defense can be interpreted as unlawful intent and may lead to arrest.
- Schools: Knives are strictly prohibited on school grounds.
- No Statewide Blade Length Limit: Outside of New York City, there is no explicit statewide blade length restriction for pocket knives, but local intent and context are crucial.
Prohibited Knives Statewide
- Switchblades
- Ballistic knives
- Metal knuckle knives
- Cane swords
- These are considered “per se” illegal weapons and cannot be possessed or carried under any circumstances.
New York City-Specific Regulations
New York City imposes additional, stricter rules:
- Blade Length Limit: It is illegal to carry any knife with a blade longer than four inches in public, regardless of the type of knife or your intent.
- Visibility: Knives must not be visible in public. Even a pocket clip or part of the handle sticking out of your pocket can result in a violation, regardless of blade length.
- Open Carry: Carrying any knife openly in public (even if not in use) is prohibited unless you are actually using it for a lawful purpose (such as work or recreation).
- Exemptions: There are limited exemptions for people using knives for work, recreation (like camping or fishing), or as part of a recognized organization (such as the Boy Scouts), but these are narrowly applied and require the knife to be transported directly to or from the activity.
Penalties for Violations
- Statewide: Unlawful possession of an illegal knife or carrying with unlawful intent is a class “A” misdemeanor, punishable by up to one year in jail. Repeat offenders may face felony charges and longer sentences.
- NYC Administrative Code Violations: Carrying a knife with a blade over four inches or carrying any knife visibly can result in up to 15 days in jail and/or a fine up to $300.
Key Takeaways
- Legal to carry a pocket knife statewide if it is not a prohibited type, you are over 16, and you do not have unlawful intent.
- In New York City: Blade must be under four inches, completely concealed, and not carried for self-defense.
- Never carry a knife onto school grounds or display it in public places.
- Intent is crucial: Carrying a knife for work or recreation is generally lawful; carrying for self-defense is not.
