Arkansas law focuses on unlawful purpose rather than treating ordinary knife carry as a permit issue. Older summaries often misstate the blade threshold, separate open carry from concealed carry, or claim that a concealed-handgun license authorizes larger knives. Those descriptions do not match the current text.
Arkansas generally permits adults to own and carry common pocket knives, fixed blades, automatic knives, OTF knives, and balisongs. Section 5-73-120 applies to a “knife” with a blade of three inches or longer, but the offense requires a purpose to attempt to unlawfully employ it as a weapon against a person. Mere lawful possession is not enough.
How does Arkansas define a knife?
For the carrying-a-weapon statute, Arkansas defines “knife” as a bladed hand instrument three inches or longer that is capable of inflicting serious physical injury or death by cutting or stabbing. The examples include a dirk, sword or spear in a cane, razor, ice pick, throwing star, switchblade, and butterfly knife. [1]
The threshold is three inches, not 3.5 inches. It defines which bladed instruments fall within this particular statute; it is not a general statewide ownership ban or an automatic carry prohibition.
Which knives may adults own?
Arkansas does not impose a general state ban on adult ownership of ordinary manual folders, fixed blades, automatic knives, OTF knives, switchblades, or balisongs merely because of blade length or opening mechanism.
The state does not require a general knife registry, ownership permit, or waiting period. Criminal use, prohibited locations, private-property rules, federal law, and a knife that serves no lawful purpose can still raise separate issues.
What is the main carry rule?
Section 5-73-120 provides that a person commits carrying a weapon if the person possesses a handgun, knife, or club on or about the person, in an occupied vehicle, or otherwise readily available for use with a purpose to attempt to unlawfully employ it as a weapon against a person. [1]
This intent element is central. The statute does not create one blade-length rule for lawful open carry and another for lawful concealed carry. It also does not state that a knife over three inches requires a concealed-handgun license.
Practical takeaway: carry a knife as a restrained, lawful tool. Avoid threatening display, statements, conduct, or circumstances suggesting an unlawful purpose. A knife that is carried during another offense can be analyzed very differently from the same knife carried for ordinary work or utility.
Do open and concealed carry have different knife rules?
Section 5-73-120 does not make the open-versus-concealed distinction described in many older guides. Both visible and concealed possession can be lawful when the knife is carried for a lawful purpose, and either can create criminal exposure when the required unlawful purpose is present.
A visible pocket clip is therefore not a statutory safe harbor, and a knife inside a pocket is not automatically illegal. Carry method can still be evidence considered with all the surrounding circumstances.
Does a concealed-handgun license expand knife carry?
No general knife authority should be inferred from a concealed-handgun license. Section 5-73-120’s license-related presumption is written for a person possessing a concealed handgun. It does not say that a handgun license authorizes concealed automatic knives, balisongs, or blades over a particular length. [1]
For knife carry, the controlling issue under this section remains the purpose to attempt to unlawfully employ the knife as a weapon against a person.
How does vehicle carry work?
The same statute expressly covers a knife in a vehicle occupied by the person or otherwise readily available for use. The offense still requires the unlawful purpose. It does not automatically classify a knife in a glove compartment, console, bag, or trunk as illegal concealed carry.
The statute also creates a presumption of lawful purpose when a person is in the person’s own dwelling, personal vehicle, place of business, or property in which the person has a possessory or proprietary interest. A journey is another listed lawful-purpose presumption, subject to the airport qualification in the statute. [1]
Keep the knife closed or sheathed and secured against movement. These presumptions do not excuse criminal use, restricted-location violations, or the law of another state.
What age restrictions apply?
Arkansas § 5-73-119 is titled “Handguns — Possession by minor or possession on school property.” Its under-18 rule addresses handguns, not ordinary knives. It should not be cited as a blanket prohibition on knife possession by every person under 18. [2]
Other laws allow an officer, without arrest, to temporarily disarm a minor who possesses a deadly weapon in specified circumstances, and a school, parent, retailer, employer, camp, or activity may impose stricter policies. Minors should use knives only with appropriate adult supervision and for a legitimate purpose.
What rules apply at schools?
The current text of § 5-73-119 addresses handguns and firearms on school property; it does not create the blanket all-knives school offense stated in the older version of this article. [2]
That does not make carrying a knife at school a sound decision. School-board policies and student codes commonly prohibit knives and other weapons more broadly. A knife carried with an unlawful purpose can also trigger § 5-73-120, and a publicly owned school building may implicate the public-building rule discussed below. Do not bring a knife to a school, school bus, or school event without clear written authorization for a specific educational or work activity.
What public-building restrictions matter?
Section 5-73-122 generally prohibits knowingly carrying a loaded firearm or other deadly weapon in a publicly owned building or facility or on the State Capitol grounds, subject to detailed exceptions. The result for a knife can depend on whether it qualifies as a deadly weapon under the circumstances. [3]
Courthouses, detention facilities, state buildings, and screened public facilities may also use security rules that are broader than the general carry statute. Follow posted rules and security instructions.
Does Arkansas preempt local knife ordinances?
Yes. Arkansas strengthened knife-specific preemption in 2025. Act 161 amended both the county and municipal provisions to bar local regulation of the ownership, transfer, transportation, carrying, or possession of knives and knife-making components, except as otherwise provided by state or federal law. [4]
Preemption does not erase state location restrictions, generally applicable criminal laws, federal law, or a public entity’s authority over its own secured property and operations where authorized by law. Private-property policies also remain separate.
What federal and private-property rules still apply?
The Transportation Security Administration prohibits knives in carry-on baggage except for plastic or round-bladed butter knives. Checked-baggage and airline requirements still apply. [5]
Private property owners, employers, and event operators may impose access or conduct policies. If asked to remove a knife or leave, comply promptly to avoid a trespass dispute.
What should you verify before carrying?
- The actual blade measurement; the § 5-73-120 definition begins at three inches.
- Your lawful purpose and whether any conduct could be interpreted as an attempt to use the knife against a person.
- Whether the destination is a publicly owned building, State Capitol property, school, federal facility, workplace, or private venue.
- Whether the knife could qualify as a deadly weapon under the circumstances.
- The law of every other state on the route.
Conclusion
Arkansas generally permits ordinary knife ownership and lawful open or concealed carry. The key statute defines covered knives at three inches or longer but requires a purpose to attempt to unlawfully employ the knife as a weapon. A concealed-handgun license is not a special knife permit, the school statute cited in many older guides is firearm-specific, and 2025 law now broadly preempts local knife regulation.
