Batons are legal in Hawaii. You can own one, carry it openly, or carry it concealed on your person or in your vehicle without committing an offense. The change came from a 2023 federal court injunction followed by an amendment to Hawaii Revised Statutes §134-51, which now explicitly exempts “billies” from the state’s concealed deadly weapons prohibition.1FindLaw. Hawaii Revised Statutes 134-51 – Deadly or Dangerous Weapons Prohibitions Penalty Carrying is lawful. Using one during a crime, or using one in a way that exceeds Hawaii’s self-defense standards, is still a felony.
What Hawaii Law Calls a Baton
The statute doesn’t use the word “baton” on its own. It uses “billy” as the umbrella term, and defines it to include a cudgel, truncheon, police baton, collapsible baton, billy club, or nightstick.1FindLaw. Hawaii Revised Statutes 134-51 – Deadly or Dangerous Weapons Prohibitions Penalty If your item fits any of those descriptions, the law treats it the same way.
How the Carry Rule Changed
For decades, Hawaii grouped billies with dirks, daggers, blackjacks, and metal knuckles as prohibited weapons, and carrying one concealed was a misdemeanor. That ended in two steps. On May 23, 2023, a federal district court in Yukutake v. Lopez entered a stipulated final judgment and permanent injunction finding that Hawaii’s carry ban on billies violated the Second Amendment. The legislature then amended §134-51 so subsection (a) now states its prohibition “shall not apply to a billy.”1FindLaw.

Where You Still Cannot Carry
The statutory exemption doesn’t override every other rule. Private property owners and businesses can set their own policies. A store, office, or venue that posts a no-weapons rule can refuse entry or ask you to leave, and refusing could result in a trespass charge. Federal buildings, courthouses, and airport security checkpoints operate under their own restrictions that state law cannot touch.
Air travel matters here because getting to and from the islands almost always means flying. The TSA prohibits nightsticks and batons in carry-on bags but allows them in checked luggage, with the screening officer making the final call at the checkpoint.2Transportation Security Administration.

Using a Baton for Self-Defense
Carrying legally and using legally are separate questions. Hawaii allows the use of force when you reasonably believe it is immediately necessary to protect yourself from another person’s unlawful force, and the force you use must be proportional to the threat.3Justia. Hawaii Code 703-304 – Use of Force in Self-Protection Swinging a baton at someone who shoved you will be judged very differently from using one against an attacker with a knife.
When a Baton Counts as Deadly Force
A baton isn’t automatically deadly force, but it crosses that line easily depending on how and where you strike. Blows to the head, neck, or spine are generally treated as deadly force regardless of the weapon. Strikes to large muscle groups like the thigh are more likely to be seen as non-deadly pain compliance, though the circumstances still matter.
Deadly force is justified only when you reasonably believe it is necessary to protect against death, serious bodily injury, kidnapping, rape, or forcible sodomy.3Justia. Hawaii Code 703-304 – Use of Force in Self-Protection Use a baton in a way that counts as deadly force against a lesser threat and you lose the self-defense justification, even if the other person started it.
Duty to Retreat
Hawaii is not a stand-your-ground state. Before using deadly force, you have to retreat if you can do so with complete safety. Two exceptions apply: you don’t have to retreat from your own home, and you don’t have to retreat from your workplace unless you were the initial aggressor or your attacker works there too.3Justia. Hawaii Code 703-304 – Use of Force in Self-Protection For non-deadly force the standard is looser, and you can estimate what’s necessary in the moment. This is where people misjudge things. Pull a collapsible baton on a public street and start swinging at someone’s head, and a prosecutor will argue that was deadly force and that you could have walked away.
Penalties if a Baton Is Used During a Crime
The exemption covers only the act of carrying. The moment you possess, use, or threaten to use a billy while committing another crime, you face a class C felony under §134-51(b).1FindLaw. Hawaii Revised Statutes 134-51 – Deadly or Dangerous Weapons Prohibitions Penalty That charge stacks on top of the underlying offense, and the sentences can run consecutively.
A class C felony in Hawaii carries up to five years in prison.4Justia. Hawaii Code 706-660 – Sentence of Imprisonment for Class B and C Felonies Ordinary Terms Discretionary Terms The court can also impose a fine of up to $10,000.5Justia. Hawaii Code 706-640 – Authorized Fines On conviction, the weapon itself is destroyed by the chief of police or sheriff.1FindLaw. Hawaii Revised Statutes 134-51 – Deadly or Dangerous Weapons Prohibitions Penalty The “separate felony or misdemeanor” language is broad. Carrying a baton during a trespass arrest or a disorderly conduct incident could trigger the weapons felony even if you never swung it at anyone.
