What's happening
This bill prohibits the manufacture, transport, shipment, and possession of undetectable knives in New York State.
Why it matters
Addresses security gaps. By targeting knives made from materials that can't be detected by metal detectors or magnetometers, the bill aims to prevent weapons from being smuggled into secure locations like airports, government buildings, and schools.
Expands legal definitions. The bill adds “undetectable knife” as a defined weapon in New York’s penal law, ensuring that these items are explicitly covered by existing laws on weapon possession and use.
Creates new criminal penalties. Manufacturing, transporting, shipping, or possessing undetectable knives will now be subject to misdemeanor criminal charges, deterring both the production and distribution of such weapons.
Closes loopholes. By including commercially manufactured undetectable knives, the bill seeks to address advancements in weapon technology (such as 3D-printed or ceramic knives) that may have previously evaded regulation.

Sponsor's memo
Title of bill
An act to amend the penal law, in relation to prohib- iting the manufacture, transport or shipment of undetectable knives and prohibiting the possession of such knives
Purpose or general idea of bill
To prohibit the manufacture, transportation, shipment and possession of an undetectable knife as defined.
Summary of specific provisions
Section 1 amends § 265.00 of the penal law to add a new subdivision 5-d "Undetectable knife" which is defined as a knife or other instrument that does not utilize materials that are detectable by a metal detector or magnetometer at standard calibrations. Additionally it further defines that the "undetectable knife" is capable of ready use as a stab- bing or cutting weapon and was commercially manufactured as a weapon
Read the full memo (626 words)
Section 2 amends § 265.01 subdivision (2) of the penal law to read that any person who possesses an undetectable knife with the intent to use unlawfully against another will be charged with a class A misdemeanor.
Section 3 amends § 265.10 subdivisions (1) and (2) of the penal law, making the manufacture, transportation or shipment of an undetectable knife a class A misdemeanor.
Justification
The original intent for the manufacture and sale of undetectable knives was based on their advantageous use for the police and military during covert operations. However, the general public has access to the purchase of these weapons through online weapons distributors, print catalogues, and other weapons outlets.
These weapons are strong enough to penetrate steel drums, car doors, wood planks, etc. without damage to the knife. These weapons are also serrated and can be sharpened with standard sharpening devices used for metal knives. It is equally troubling that they are advertised as being non-magnetic and can escape detection. In one instance, an undetectable knife was used in a Compton, California courtroom, where a defendant smuggled a ten-inch non-metallic knife past metal detectors and stabbed two bailiffs.
These weapons present a severe security risk to any building that utilizes a metal detector for the prevention of violence or possible terrorist acts. The proliferation of these knives in our society aide those who seek to inflict harm in areas where security is closely moni- tored. We know firsthand how the possession of a seemingly innocuous tool was used to hijack three planes and take thousands of lives. We must learn from prior complacency and assume the role of a legislative body that acts before a scheme targeting innocents materializes into reality.
Possession of an "undetectable knife" would become a Class A misdemeanor under section 256.01 of the Penal Law.
Manufacture, transportation or shipping of an "undetectable knife" would become a Class A misdemeanor under section 256.10 of the Penal Law.
Upon conviction of either offense, a court could sentence an individual to a maximum of one year in jail or three years probation. Addi- tionally, the court may impose a fine up to $1000 or twice the maximum amount of any gain derived.
Exemption to for military, police and others: This bill would allow members of the military, police officers and other persons exempted from the possession, transportation or shipment provisions in § 265.01 and § 265.10 of the penal law, to retain or obtain this weapon for official use. The statutory authority for this exemption derives from § 265.20 of the penal law.
This legislation is modeled after a provision in California's "Dangerous Weapons Control Law.
