Florida knife law is broadly permissive, but it is not unlimited. As of March 2026, the Florida statutes reviewed do not impose a general statewide blade-length cap and do not generally ban common knife types, but ballistic self-propelled knives are banned statewide. Open carry of knives is generally lawful under state law, while concealed carry of knives is generally lawful for people who satisfy Florida’s post-2023 concealed-carry rules. This is legal information, not legal advice. (Florida Legislature)
Quick Answer
Florida is relatively permissive on knives, but the key issues are ballistic knives, concealed-carry eligibility, school rules, restricted places, and local ordinances. (The Florida Senate)
The current Chapter 790 definitions matter because Florida excludes a “common pocketknife” from the chapter definition of “weapon” in Fla. Stat. § 790.001(20), while Fla. Stat. § 790.06(1)(a) separately defines a “concealed weapon or concealed firearm” for licensing and carry purposes to include a knife. Since the 2023 law change, the main statewide concealed-carry question is usually whether the person qualifies under Fla. Stat. § 790.01(1), not whether the knife falls into a special category such as a dirk or dagger. (Florida Legislature)
Most knives are legal to own in Florida. (Florida Legislature)
The current statutes reviewed do not identify ordinary folding knives, fixed blades, daggers, dirks, bowie knives, butterfly knives, gravity knives, or double-edged knives as generally prohibited categories for adult ownership statewide. The clearest statewide knife ban identified in the reviewed Florida statutes is the ban on ballistic self-propelled knives in Fla. Stat. § 790.225. (Florida Legislature)
Under state law, open carry of knives is generally lawful in Florida. (The Florida Senate)
That conclusion follows from Fla. Stat. § 790.053, which prohibits openly carrying a firearm or electric weapon or device, but does not list knives. That said, openly displaying a dirk, sword, sword cane, or other weapon in a rude, careless, angry, or threatening manner can still violate Fla. Stat. § 790.10, and school-related conduct has separate rules under Fla. Stat. § 790.115. Local ordinances can also narrow what is safe in practice. (Florida Legislature)
Yes, concealed carry of a knife is generally lawful in Florida for people who qualify under the current concealed-carry statute. (The Florida Senate)
Since July 1, 2023, Florida law has authorized concealed carry of a “concealed weapon or concealed firearm” for a person who either holds a license or satisfies the eligibility criteria for one under Fla. Stat. § 790.01(1). Fla. Stat. § 790.06(1)(a) expressly includes a knife within that concealed-carry definition, and Fla. Stat. § 790.013 requires a person carrying without a license under that pathway to carry valid identification and comply with the same restricted-place rules that apply to licensees. (The Florida Senate)
For most residents, that means concealed knife carry is generally lawful if the person is at least 21 and otherwise meets the disqualifier rules incorporated from Fla. Stat. § 790.06(2), (3), and (10). Fla. Stat. § 790.23 separately makes it unlawful for certain felons and delinquent offenders to carry a concealed weapon. (The Florida Senate)
Florida still excludes a “common pocketknife” from the chapter definition of “weapon” in Fla. Stat. § 790.001(20). That exception still matters in some offense-specific situations, but after the 2023 carry change, it is no longer the main statewide question for otherwise qualified adults carrying a knife concealed. (Florida Legislature)
Under current statewide Florida law, those knife types are generally not banned as categories, but ballistic knives are banned and local or federal rules can still change the result. (The Florida Senate)
The reviewed Florida statutes do not expressly create a general statewide ban on switchblades, automatic knives, butterfly knives, or double-edged knives. Fla. Stat. § 790.225 does, however, ban ballistic self-propelled knives. Federal law separately regulates switchblades in interstate commerce and certain federal jurisdictions, and Miami-Dade County currently has its own ordinance against switchblade-style knives. (The Florida Senate)
Florida’s current statutes do not impose a general statewide blade-length limit. (Florida Legislature)
The often-repeated “4-inch rule” is not a general statewide blade-length statute. It comes from older Florida litigation about what counts as a “common pocketknife,” and later cases show that the issue can still depend on more than blade length alone. The better reading for compliance purposes is that Florida has no general statewide blade-length cap, while the “common pocketknife” exception remains a narrower, offense-specific concept. (Florida Legislature)
Florida restricts knives mainly through school-property rules and through the concealed-carry restricted-place list. (The Florida Senate)
For concealed carry, Fla. Stat. § 790.06(12), incorporated into unlicensed concealed carry by Fla. Stat. § 790.013, bars carrying a concealed weapon or concealed firearm into places such as police, sheriff, or highway patrol stations; detention facilities, prisons, and jails; courthouses and courtrooms; polling places; meetings of local governing bodies or the Legislature; school, college, or professional athletic events not related to firearms; elementary or secondary school facilities and administration buildings; career centers; bar areas primarily devoted to on-premises alcohol consumption; most college or university facilities; airport passenger terminals and sterile areas; and any place where federal law prohibits firearms. (The Florida Senate)
Schools deserve separate attention. Fla. Stat. § 790.115 prohibits possession of a firearm, electric weapon, destructive device, or other weapon as defined in Fla. Stat. § 790.001 at school-sponsored events, on school property, on school buses, and at school bus stops, and it separately criminalizes rude, careless, angry, or threatening exhibition there or within 1,000 feet of a school during school hours or a sanctioned activity. Because that school-possession rule cross-references the chapter definition of “weapon,” and the chapter definition excludes a common pocketknife, school cases can become technical. The safest practical approach is to avoid carrying knives onto K-12 school property or school events unless clearly authorized. (The Florida Senate)
Yes, Florida has minor-related knife transfer restrictions even though it does not impose a broad statewide knife ownership ban. (Florida Legislature)
Under Fla. Stat. § 790.17, a person may not sell, lend, transfer, or give a minor under 18 a dirk, electric weapon, or other weapon, other than an ordinary pocketknife, without parental or guardian permission. Fla. Stat. § 790.18 separately makes it unlawful for a dealer in arms to sell or transfer a bowie knife or dirk knife to a minor. (Florida Legislature)
No, Florida does not have a general statewide knife-law preemption statute. (The Florida Senate)
Fla. Stat. § 790.33 expressly preempts the field of firearms and ammunition regulation, not knives. Florida also has statutory language about statewide uniformity in concealed-carry licensing, but that is not the same thing as a broad preemption rule wiping out all local knife ordinances. (The Florida Senate)
Yes, local knife ordinances still matter in Florida. (The Florida Senate)
Miami-Dade County is the clearest current example. Miami-Dade Code § 21-14 prohibits certain concealed dangerous weapons and separately prohibits switchblade-style knives that open by a button, handle pressure, or other mechanical contrivance. Because Florida does not generally preempt knife regulation statewide, local checks remain important before carrying in a particular city or county. (Florida Miami-Dade)
Federal law still matters for switchblades, ballistic knives, mailing, and air travel. (U.S. Code)
The Federal Switchblade Act in 15 U.S.C. §§ 1241-1245 regulates switchblades in interstate commerce and certain federal jurisdictions, and 18 U.S.C. § 1716 treats switchblades and ballistic knives as nonmailable except in limited situations. TSA rules separately prohibit knives in carry-on bags, although knives are generally allowed in checked baggage if properly packed. Those federal rules are separate from Florida state law. (U.S. Code)
Florida is relatively favorable to knife owners, but the practical pressure points are ballistic knives, school-related rules, concealed-carry restricted places, prohibited-status issues, and local ordinances. (The Florida Senate)
| Issue | Florida rule |
|---|---|
| Ownership | Most knives are legal to own statewide; ballistic self-propelled knives are banned. Fla. Stat. § 790.225. |
| Open carry | Generally lawful for knives under state law because Fla. Stat. § 790.053 targets firearms and electric weapons, not knives. Threatening exhibition can still be criminal under Fla. Stat. § 790.10. |
| Concealed carry | Generally lawful for a person who qualifies under Fla. Stat. § 790.01(1); Fla. Stat. § 790.06(1)(a) includes a knife in the concealed-carry definition; Fla. Stat. § 790.013 requires ID for unlicensed authorized carry. |
| Automatic / switchblade / butterfly / double-edged | No general statewide category ban identified in the current Florida statutes reviewed, but local and federal rules can still matter. |
| Blade length | No general statewide blade-length cap appears in the current statutes. The “common pocketknife” discussion is narrower than a statewide blade-length rule. Fla. Stat. § 790.001(20). |
| Schools | High-risk area. Fla. Stat. § 790.115 restricts possession and threatening exhibition at school events, school property, buses, bus stops, and nearby areas in some circumstances. |
| Restricted places | For concealed carry, Fla. Stat. § 790.06(12) and Fla. Stat. § 790.013 restrict police stations, jails, courthouses, polling places, government meetings, certain athletic events, school facilities, bars, colleges, airport sterile areas, and more. |
| Vehicles | A person 18 or older may keep a handgun or other weapon in the interior of a private conveyance if securely encased or not readily accessible for immediate use; qualifying persons may also carry concealed on the person in a private conveyance. Fla. Stat. § 790.25(4). |
| Minors | Fla. Stat. § 790.17 restricts furnishing certain weapons to minors; Fla. Stat. § 790.18 restricts dealer sales of bowie knives and dirk knives to minors. |
| Preemption / local law | No general statewide knife preemption. Fla. Stat. § 790.33 preempts firearms and ammunition, not knives. Local rules still matter. |

Florida’s major recent statewide carry change was the 2023 law that authorized permitless concealed carry for qualifying people. (The Florida Senate)
CS/HB 543 became Chapter 2023-18 and took effect on July 1, 2023. It authorized concealed carry by a person who is either licensed or otherwise meets the statutory criteria, created Fla. Stat. § 790.013’s identification requirement for unlicensed authorized carry, and applied Fla. Stat. § 790.06(12)’s restricted-place rules to that carry. As of March 20, 2026, the reviewed Florida legislative sources did not show a later enacted statewide knife-specific overhaul. A 2026 school-safety bill, HB 757, was moving through the process and SB 896 was laid on the table in favor of it, but the reviewed sources did not show that measure as current law in force on March 20, 2026. (The Florida Senate)
Generally yes under statewide Florida law, but federal rules and local ordinances can still matter. Florida’s statewide statute reviewed does not create a general switchblade ban, but Miami-Dade County currently bans switchblade-style knives and federal law still regulates switchblades in interstate commerce and mailing contexts. (The Florida Senate)
No general statewide 4-inch blade limit appears in Florida’s current statutes. The 4-inch figure comes from older “common pocketknife” case law, not from a present statewide blade-length statute. (Florida Legislature)
Usually yes. Fla. Stat. § 790.25(4) allows a person 18 or older to keep a handgun or other weapon in the interior of a private conveyance if it is securely encased or otherwise not readily accessible for immediate use, and qualifying persons may also carry concealed on the person in a private conveyance. (Florida Legislature)
Florida law makes this issue narrower than many readers expect. Fla. Stat. § 790.23 expressly bars certain felons and delinquent offenders from carrying a concealed weapon, but the reviewed statutes do not create the same kind of broad statewide knife-possession ban that Florida applies to firearms, ammunition, and electric weapons. That makes status-based knife questions fact-sensitive and worth getting individual legal advice on. (Florida Legislature)
Yes. Florida’s express preemption statute covers firearms and ammunition, not knives, and Miami-Dade remains a current example of a county ordinance that regulates certain knives. (The Florida Senate)
That is one of the riskiest areas. Fla. Stat. § 790.115 creates school-property and school-event weapon restrictions, and even threatening exhibition of a common pocketknife can trigger the school statute in some circumstances. (The Florida Senate)
Laws can change, local rules may still apply, and restricted places, intent, and personal status can all affect whether carrying a knife is lawful in Florida. (The Florida Senate)
