New York Knife Laws (2026) – What You Can Legally Carry
New York knife laws are among the most complex in the United States, with significant differences between state law and local ordinances, particularly in New York City. Understanding these laws is crucial for knife owners, collectors, and anyone who carries knives for work, outdoor activities, or everyday use.
This comprehensive guide covers New York knife laws as they stand in 2026, including the historic gravity knife ban repeal, current legal carry options, prohibited weapons, and the critical distinctions between state law and New York City regulations.
Understanding New York’s Dual Knife Law System
New York operates under a complex system where state law provides the baseline regulations, but local jurisdictions—especially New York City—can impose stricter rules. There is no statewide preemption, meaning cities and counties can create more restrictive knife laws than the state requires.
Key Legal Framework
New York knife laws focus heavily on two critical factors:
- Blade length: The 4-inch threshold is crucial for legal carry
- Intent: Carrying with unlawful intent makes even legal knives illegal
This intent-based approach means that context matters significantly in enforcement decisions.
Legal Knives You Can Carry in New York
Statewide Legal Knives (Under 4 Inches)
The following knives are legal to carry throughout New York State if the blade is under 4 inches:
- Folding pocket knives – Traditional and modern folders
- Fixed-blade knives – Including hunting and outdoor knives
- Gravity knives – Legal since the 2019 ban repeal
- Kitchen knives – For culinary professionals and home use
- Utility knives – Work-related cutting tools
- Multi-tools – With knife blades under 4 inches
The Gravity Knife Revolution (2019 Change)
One of the most significant changes in New York knife law was the repeal of the gravity knife ban on May 30, 2019. Previously, thousands of people were arrested for carrying gravity knives, often including common folding knives that could be opened with wrist action.
What changed:
- Mere possession of gravity knives is no longer a crime
- Working people can carry tools without fear of arrest
- Focus shifted to design and intent rather than opening method
Concealed vs. Open Carry Rules
New York State
New York State law does not distinguish between concealed and open carry for legal knives under 4 inches. As long as the knife complies with length and type restrictions, it can be carried either way for lawful purposes.
New York City – Major Exception
NYC completely prohibits visible carry of ANY knife in public. This means:
- ALL knives must be carried concealed in NYC
- No exceptions for folding knives or small blades
- Violation can result in arrest and prosecution
- Even legal knives become illegal if carried visibly
Prohibited Knives in New York
The following knives are illegal to possess, carry, or sell in New York:
Completely Banned Statewide
- Switchblades (automatic knives): Spring-loaded knives that open with button activation

- Metal knuckle knives: Knives combined with brass knuckles or similar weapons
- Cane swords: Swords concealed within walking canes
- Butterfly knives (balisongs): Knives with two handles that rotate around the tang
Important note: Assisted-opening knives may be treated as switchblades under New York law following court decisions, making them legally risky.
