Are Brass Knuckles Illegal to Own? State Laws Explained
Brass knuckles are illegal to own in some states. Other states regulate carrying, selling, or transferring them differently. Keeping a pair at home, taking them into public, and ordering them online can involve separate rules. A product being available for sale does not establish that you can legally possess it where you live.
This guide explains the distinctions that matter, compares laws in 14 states, and links to government sources so you can investigate your own situation before buying or traveling.
This is general information, not legal advice or an attorney-reviewed legal opinion. The comparison covers selected state provisions, not every state, local ordinance, exemption, or court ruling. Consult a licensed attorney in the relevant jurisdiction for a specific legal determination.
What are brass knuckles, and what does the law consider?
Brass knuckles generally describe a hand-held or hand-worn striking device. Traditional examples have openings for the fingers, but legal definitions can reach beyond a familiar four-hole shape. The item's construction, intended function, and the wording of the applicable statute matter more than its retail category.
For example, California's official peace officer training materials discuss both metal knuckles and composite knuckles as prohibited weapon categories. Their discussion of metal knuckles covers devices made partly or entirely from metal; the name does not mean that only brass is relevant. See the California POST weapons workbook, striking weapons section.
When reviewing our brass knuckles and hand-casted paperweights collection, treat the product title as a description of the listing. It is not a legal determination for your location. American manufacture, custom engraving, or a collectible finish does not create an exemption from weapons laws.
Owning, carrying, and selling brass knuckles are different legal questions
The question “Are brass knuckles legal?” needs a specific activity and location. These distinctions explain why two short online answers about the same state can appear to conflict.
| Activity | Question to investigate |
|---|---|
| Possession at home | Does the law prohibit having the item, even if it stays in a drawer or display case? |
| Carrying in public | Does the law restrict carrying on your person, carrying concealed, or control of the item in a vehicle? |
| Buying, selling, or giving | Are purchase, manufacture, advertising for sale, gifting, lending, or other transfers restricted? |
| Travel and shipping | What rules apply at the origin, destination, intermediate locations, security checkpoints, and delivery address? |
| Threatening or using | What separate criminal laws govern the conduct? Permission to possess an item does not authorize a threat or assault. |
A concealed handgun permit also should not be treated as permission to carry every kind of weapon. Virginia, for example, lists metal knucks in its concealed weapons prohibition but describes its permit defense specifically in relation to a handgun. Read Virginia Code § 18.2-308 rather than assuming firearm rules apply to knuckles.
Brass knuckles laws by state: 14 examples with official links
This is a selected-state comparison, not a 50-state legality chart. The summaries identify important statutory restrictions for ordinary civilian circumstances. They do not resolve every exception or authorize a purchase, shipment, or particular method of carrying.
| State | Important distinction | Official source |
|---|---|---|
| California | Possession of metal knuckles is prohibited, subject to statutory exemptions. Do not assume that keeping them at home or calling them a paperweight provides an exemption. | Penal Code § 21810; POST weapons guidance |
| Colorado | The statute classifies metallic knuckles as an illegal weapon and prohibits knowingly possessing one. It also specifies affirmative defenses; those should not be assumed to apply to an ordinary purchase. | C.R.S. § 18-12-102, 2026 Title 18 |
| Florida | Manufacturing metallic knuckles and selling or displaying them for sale are prohibited. Concealed carrying is a separate question governed by eligibility and other weapons provisions. | § 790.09, manufacture and sales; § 790.01, concealed carrying |
| Illinois | The law covers having, buying, carrying, producing, and selling metal knuckles and other knuckle weapons, including designs made from other materials. Statutory exceptions require separate analysis. | 720 ILCS 5/24-1(a)(1) |
| Massachusetts | Section 10(b) restricts carrying knuckles on the person or under one's control in a vehicle. Section 12 separately restricts manufacture and sales. Both provisions address nonmetal designs with comparable effects. | Chapter 269, § 10(b); § 12 |
| Michigan | Manufacturing, selling, offering for sale, and possessing metallic knuckles are prohibited, subject to statutory exceptions. The restriction is not limited to concealed carrying. | MCL 750.224 |
| New Jersey | Knowingly possessing a metal knuckle without an explainable lawful purpose is prohibited. Whether a purpose qualifies is a legal question; a seller's collectible label does not settle it. | N.J.S. 2C:39-3(e), reproduced in enacted P.L. 2025, Chapter 255 |
| New York | The possession offense expressly includes metal knuckles, plastic knuckles, and metal knuckle knives. It is not merely a rule against carrying concealed. | Penal Law § 265.01(1) |
| North Carolina | Section 14-269(a) prohibits intentionally carrying metallic knuckles concealed about the person, with an exception for one's own premises and specified exemptions. Educational property has separate restrictions. | G.S. 14-269; G.S. 14-269.2 |
| Oregon | ORS 166.240 addresses carrying metal knuckles concealed on the person, subject to specified exemptions. That provision should not be read as a general ban on every instance of home ownership. | ORS 166.240 in Chapter 166 |
| Pennsylvania | Metal knuckles are included among prohibited offensive weapons. Possession and dealing are restricted. The section provides defenses, including certain possession solely as a curio; those defenses depend on the actual circumstances. | 18 Pa.C.S. § 908 |
| Texas | Texas removed knuckles from its prohibited weapons list effective September 1, 2019. That repeal is important for ownership, but it does not authorize unlawful conduct or override other applicable restrictions. | Enacted H.B. 446; current Penal Code Chapter 46 |
| Virginia | Concealed carrying is restricted. A separate statute restricts sales, barter, gifts, furnishing, and possession with intent to make those transfers. Simple ownership, concealed carrying, and giving a pair away require different analysis. | § 18.2-308; § 18.2-311 |
| Washington | The statute prohibits possessing, manufacturing, selling, or disposing of metal knuckles. Its possession rule is separate from its provision about secretly carrying other dangerous weapons. | RCW 9.41.250 |
If your state is not listed, that does not mean brass knuckles are legal there. Use the Congress.gov directory of state legislature websites to locate official laws. Search for “brass knuckles,” “metal knuckles,” “metallic knuckles,” “knucks,” “knuckle weapon,” and “offensive weapons.” Check municipal rules and relevant court decisions as well.
Why Texas, Florida, and Virginia need different answers
Texas: an old prohibition was repealed
Older articles may still describe Texas knuckles as prohibited weapons. The legislature's H.B. 446 summary explains that the 2019 law removed knuckles from that list. The effective date was September 1, 2019.
The accurate takeaway is that the former statewide knuckles prohibition was removed. “Legal everywhere, for everyone, in every circumstance” would be a much broader claim. A reader still needs to consider location, conduct, and other applicable rules.
Florida: carrying eligibility does not erase a sales prohibition
Florida's manufacture and sales statute is an important reason to avoid a one-word answer. The definitions section includes metallic knuckles within its concealed weapon terminology.
Under § 790.01, concealed carrying authorization depends on a license or satisfaction of specified licensing criteria. Permitless carrying provisions do not make everyone eligible, and they do not repeal § 790.09. A claim that Florida simply allows unrestricted buying and carrying misses these separate issues.
Virginia: possession and transferring an item are not interchangeable
Virginia's transfer restriction reaches beyond commercial sales to activities such as giving or furnishing brass or metal knucks. It also addresses possession with the intent to make those transfers. A proposed gift can therefore raise a different issue from an item already held at home. Read the separate concealed carrying rule before taking one into public.
Are brass knuckle paperweights or collector pieces exempt?
A “paperweight” label does not decide the legal classification
Retailers may describe a knuckle-shaped item as a paperweight, desk accessory, novelty, or collectible. The practical conclusion from the statutes above is to examine the actual item against the legal definition. None of those marketing words establishes a nationwide exemption.
A lawful use or collector defense, where one exists, must come from the applicable law and fit the facts. Do not assume that packaging, a product disclaimer, or an intended place on a desk resolves a possession prohibition.
Collector exceptions must be evaluated individually
Pennsylvania provides a useful example. Section 908(b) sets out a defense involving possession solely as a curio, along with other specified circumstances. That is a legal defense with conditions, not automatic permission for every object advertised as collectible. It also does not establish an exemption in another state.
Plastic, resin, and other materials are not automatically unrestricted
New York expressly lists plastic knuckles. Illinois covers other knuckle weapons made from materials besides metal. Massachusetts addresses knuckles made from substances capable of comparable use and effects. These examples show why replacing brass with another material is not a reliable legal shortcut.
Likewise, examine an item with an integrated blade under all relevant definitions. A product can raise both knife and knuckle questions. Our collectible and custom knife buying guide and folding and pocket knife collection provide product context; neither determines whether a particular design is lawful in your jurisdiction.
Can you travel with brass knuckles?
TSA prohibits brass knuckles in carry-on bags
The TSA brass knuckles page lists them as prohibited in carry-on baggage and permitted in checked baggage for screening purposes. TSA also warns that these items remain illegal in some states. A checked-baggage allowance is not a determination that possession is lawful at either end of the trip. Confirm current TSA, airline, and applicable jurisdiction rules before traveling.
Schools, vehicles, and secure buildings require separate checks
A rule about home possession does not settle what happens in a vehicle, at school, or inside a secure building. North Carolina's educational property statute, for example, specifically addresses metallic knuckles whether openly carried or concealed. Massachusetts expressly addresses control of listed weapons in a vehicle.
Federal facilities may impose their own restrictions as well. For a concrete example, the IRS physical access policy includes brass knuckles among prohibited striking devices. Check the rules for the particular destination instead of treating a state ownership rule as universal permission to enter.
Does a constitutional challenge automatically suspend a ban?
No general argument about constitutional rights substitutes for checking the law and controlling court orders. In People v. Dummer, decided March 18, 2025, Michigan's Court of Appeals rejected a facial constitutional challenge to the metallic knuckles possession prohibition. That ruling illustrates why a reader should not assume an existing statute has disappeared because someone questions its constitutionality.
What to check before buying brass knuckles online
- Identify the exact item. Review photographs, material descriptions, dimensions, and any integrated blade or other feature. Save the information needed to compare the design with the statutory definition.
- Separate the activities. Check possession, purchase, sale, shipment, carrying, and gifting individually. A rule that answers one activity may not answer another.
- Start with the current official text. Follow the state links above and check amendments and effective dates. A proposed bill is not an enacted change.
- Check the relevant places and people. Consider local rules, restricted properties, age requirements, and any individual legal restrictions. Do not apply a specialized occupational exemption to ordinary civilian ownership.
- Confirm uncertainty before ordering. Ask a licensed attorney when a definition, defense, court ruling, or shipment question is unclear. Checkout availability is not legal clearance.
If the item is lawful for your circumstances, you can review materials, finishes, and maker information in our brass knuckles and paperweights collection. You can also explore the broader Tactical & Outdoor collection. Evaluate each product independently; another product category is not a guarantee of unrestricted ownership or carrying.
Frequently asked questions about brass knuckles laws
Are brass knuckles illegal to own in all 50 states?
No. State laws differ. Texas removed knuckles from its prohibited weapons list in 2019, while states such as New York, Michigan, and Washington have possession prohibitions. A state without that particular prohibition may still regulate other activities or locations.
Can I keep brass knuckles at home if I never carry them?
Not necessarily. A law prohibiting possession can apply without public carrying. Keeping an item in a display case does not by itself resolve that prohibition. Read the applicable statute and any relevant exemption or defense.
Are brass knuckles legal in Texas?
Texas repealed its specific prohibited-weapons restriction on knuckles effective September 1, 2019. That change does not override laws governing unlawful conduct or restrictions that may apply to a particular place or person.
Are brass knuckles legal in Florida?
A single yes-or-no answer is incomplete. Florida prohibits manufacture and sales of metallic knuckles under § 790.09. Concealed carrying is governed separately by § 790.01 and related provisions. Check the activity and the applicable eligibility rules.
Does calling brass knuckles a paperweight make them legal?
No label creates a nationwide exemption. Classification depends on the applicable legal definition and facts about the item. A collector defense in one state does not automatically apply elsewhere.
Are plastic or resin knuckles legal?
Do not assume so. New York expressly includes plastic knuckles, while Illinois and Massachusetts use language that can cover nonmetal designs. The material name alone is not enough to decide legality.
Does a concealed carry permit cover brass knuckles?
Do not assume a handgun permit covers other weapons. Virginia's statute illustrates the distinction: it addresses metal knucks separately and describes its concealed handgun permit defense in relation to a handgun. Read the law for the particular weapon and jurisdiction.
Can I bring brass knuckles on an airplane?
TSA prohibits them in carry-on baggage and lists them as allowed in checked baggage for screening purposes. State possession laws, destination rules, and airline requirements still need to be checked.
Is illegal possession always a misdemeanor?
No. The classification varies by state and circumstances. Michigan's MCL 750.224 treats a violation as a felony, while Washington's RCW 9.41.250 specifies a gross misdemeanor. Do not assume the consequences are minor because the item is sold online.
