Can a New York village exhibit antique switchblades and gravity knives in a local museum without breaking the Penal Law?

Plain-English summary

The Village of Walden, New York wanted to memorialize its history as a knife-manufacturing town. From the 1890s through the 1950s, three knife-making companies operated in the Village. The plan was a museum or gallery to display knife collections from that era. Some of those knives, by their construction, fell into per se illegal categories under the Penal Law: switchblade, gravity, pilum ballistic, and metal knuckle knives.

The Village asked whether displaying that kind of collection would violate state law. The AG answered: yes, unless the knives are first physically disabled.

Penal Law § 265.01(1) criminalizes possession of those four classes of knife as a class A misdemeanor, with no requirement that the possessor intend to use it unlawfully. The mere possession is the offense. People v. Talbert and People v. Dolson confirm the per se reading. The Penal Law § 265.01(2) offense, which requires intent to use a "dangerous knife" unlawfully, is a separate, intent-based crime; it has no bearing on the per se categories.

Penal Law § 265.20 contains the standard exemptions for weapons offenses. Law enforcement and corrections officers, prison and military personnel, and licensed firearm carriers all have carve-outs (§ 265.20(1)(a)-(e), (2), (3)). The hunting/trapping/fishing exception in § 265.20(6) permits possession of a switchblade or gravity knife while engaged in those activities under a valid license. But there is no museum exception, no cultural-display exception, and no educational exception. The AG looked elsewhere in state law and found no equivalent carve-out either.

That left the only lawful path: render the knives non-functional in a way that removes them from the statutory definitions. Penal Law § 265.00(4) through (5-b) define each per se illegal knife by reference to the mechanism that makes it dangerous (the spring that opens a switchblade automatically, the pivot that locks a gravity knife). Remove the mechanism, and the object is no longer a "switchblade knife" or "gravity knife" under the Penal Law. It is, at that point, a historic artifact rather than a weapon.

The AG specifically suggested working with the New York State Museum, which staff there had agreed to advise on the practical mechanics of disabling.

The opinion is narrow: it does not address whether a museum could lawfully accept loans or donations of currently functional banned knives. It assumes the Village would handle the disabling itself before placing the items on display.

Common questions

Q: Why are switchblades and gravity knives illegal to merely possess?
A: Penal Law § 265.01(1) makes possession a class A misdemeanor regardless of intent. The Legislature treated these as per se dangerous because of the mechanism by which the blade is deployed.

Q: Is there any cultural or historical-display exemption?
A: No. The AG examined the Penal Law § 265.20 catalog of exemptions and found nothing covering possession by a municipality, museum, or other cultural entity for display purposes. No other state law supplied the exemption either.

Q: How can a museum lawfully display these items?
A: The knife has to be disabled so it no longer fits the statutory definition. The definitions in Penal Law § 265.00(4) through (5-b) describe each banned knife in terms of its opening or locking mechanism. Removing or disabling that mechanism (the spring, the pivot, the lock) brings the object outside the definition.

Q: Does this apply to bayonets, fixed-blade knives, or other historic blades?
A: No. Those are not per se illegal under § 265.01(1). The mere-possession ban is limited to switchblade, gravity, pilum ballistic, and metal knuckle knives. A regular fixed-blade or non-mechanical folding knife is not in that category.

Q: Could a museum borrow disabled knives from collectors who already disabled them?
A: The opinion did not address that question. The Village's plan was to display knives that included currently banned types, and the AG addressed the legality of the display, not the chain of custody before disabling.

Q: Where can a municipality get practical guidance on disabling these knives?
A: The AG specifically named the New York State Museum as having agreed to provide additional practical advice on the mechanics.

Background and statutory framework

Penal Law Article 265 governs criminal possession of weapons. Section 265.01 lists the fourth-degree offenses. Subdivision (1) is a possession-only offense for specifically defined per se illegal items: firearms not authorized for the possessor, switchblade knives, gravity knives, pilum ballistic knives, and metal knuckle knives. Subdivision (2) catches possession of "any dangerous knife" with intent to use it unlawfully against another, which sweeps broader but requires intent.

The definitions in Penal Law § 265.00 list the mechanical features that make each per se illegal knife dangerous. A switchblade is one whose blade opens automatically by spring; a gravity knife has a blade that, once unlocked, swings open by gravity or inertia and locks in place. The Court of Appeals and various Appellate Division decisions (not cited in the opinion but reflected in the definitions) have parsed these mechanisms in detail.

The exemption catalog in Penal Law § 265.20 is the standard place to look for an exception to a possession offense. Subdivision (1)(a)-(e) and (2) cover law enforcement, prison, and military personnel. Subdivision (3) is for licensed firearm carriers, with no analog for knives. Subdivision (6) permits switchblade or gravity knife possession while hunting, trapping, or fishing under a valid license. Nothing in the list reaches museum or cultural display.

The AG's "remove the mechanism" workaround leans on the structure of the definitions: take away the defining feature and the item is no longer a "switchblade" or "gravity knife" within the statute's meaning. The opinion expressly recommended consulting the New York State Museum on the practical execution of that disabling.

PENAL LAW §§ 164.01, 265.00; 265.20.

A municipality may not lawfully display knives designated as illegal to possess under Penal Law § 265.01(1), unless they are disabled in such a manner as to bring them outside the scope of the applicable Penal Law definitions.

Informal Opinion
No. 2004-2

Dear Mr. Dowd:

In your capacity as village attorney for the Village of Walden, you have asked whether the Village would be in violation of State law if it displayed in a museum or gallery knife collections that include switchblade knives that are illegal to possess under the Penal Law. You have indicated that the Village is considering establishing a museum or gallery to commemorate the role the Village has played in the history of knife-manufacturing in this State.

As you are aware, under Penal Law § 265.01(1), a person is guilty of criminal possession of a weapon in the fourth degree, a class A misdemeanor, if he possesses, inter alia, a "gravity knife, switchblade knife, pilum ballistic knife, [or] metal knuckle knife." Under this provision, the mere possession of one of the listed items constitutes a violation of the law. See People v. Talbert, 107 A.D.2d 842, 843 (3d Dep't 1985); People v. Dolson, 140 Misc.2d 240 (City Ct. 1987); cf. Penal Law § 265.01(2) (criminalizing possession of any dangerous knife "with intent to use the same unlawfully against another"). These per se illegal knives are specifically defined in the Penal Law. See Penal Law § 265.00(4) through (5-b).

As you noted in your letter, various exemptions to the possession of illegal weapons are set forth in Penal Law § 265.20. With respect to weapons other than firearms, these exemptions include possession by law enforcement, prison and military personnel, id. § 265.20(1)(a)-(e), (2), and the possession of a switchblade or gravity knife while hunting, trapping or fishing pursuant to a valid license, id. § 265.20(6). Although firearms that are otherwise per se illegal to possess (pistols and revolvers) may be possessed by individuals licensed to carry them, see id. § 265.20(3), there are no provisions for the licensing of otherwise illegal knives.

In sum, none of the exemptions in Penal Law § 265.20 covers possession by a local government, municipal agency, or museum for display purposes. Nor are we aware of any other state law that exempts the possession of per se illegal weapons when displayed for educational, cultural or historical purposes.

While we conclude that the Village and its authorized agents may not lawfully display those knives that are designated as illegal to possess under Penal Law § 265.01(1), we believe the Village could legally display the knives if they are disabled in such a manner as to bring them outside the scope of the applicable Penal Law definitions. See Penal Law § 265.00(4) through (5-b) (defining each type of per se illegal knife). That is, the knives should be fully disabled so that they can no longer be used in an illegal manner. For example, because the definitions of switchblade knife and gravity knife define these knives in terms of the mechanisms that cause the blade to open automatically (switchblade) or lock into place (gravity knife), the devices in the knife that cause the blade to spring (or pivot) and lock should be removed. Staff at the New York State Museum, with whom we consulted in response to your inquiry, have agreed to assist you in obtaining additional practical advice on this issue.

The Attorney General issues formal opinions only to officers and departments of State government. Thus, this is an informal opinion rendered to assist you in advising the municipality you represent.

Very truly yours,

LAURA ETLINGER
