Swords are legal to own in Massachusetts without a permit or license, but carrying one in public is a different matter and can be prosecuted as carrying a dangerous weapon. The state has no sword-specific statute and no carry permit for blades, so a sword’s legality turns on where it is, how it is being handled, and whether its design matches weapons the law bans outright.
Owning a Sword at Home
You can keep swords in your home for display, collection, or martial arts practice. No permit, no license, no registration. Massachusetts does not regulate home possession of swords the way it does firearms, which require a Firearms Identification Card even for storage.
There are no state-mandated storage rules, but practical caution matters. If an unsecured sword leads to someone being hurt, you can face civil liability for negligence. A locked display case or a room with restricted access is sensible if you have children or regular visitors. Standard homeowners insurance typically covers accidental injuries on your property but excludes intentional harm, so if you injure an intruder, coverage will depend on whether a court finds the force reasonable.
Brandishing a sword at someone inside your home can still lead to assault charges. Ownership is lawful; threatening use is not.
Carrying a Sword in Public
This is where people get into real trouble. Massachusetts offers no carry permit for swords. Unlike firearms, which have a licensing framework for lawful carry, there is no legal mechanism to carry a sword on your person in public.
The governing statute is Massachusetts General Laws Chapter 269, Section 10(b). It lists specific weapons that cannot be carried on the person or in a vehicle, including stilettos, daggers, double-edged knives, ballistic knives, switch knives, blowguns, metallic knuckles, nunchaku, and shuriken.1General Court of Massachusetts. Massachusetts General Laws Chapter 269, Section 10 A double-edged sword likely qualifies as a “knife having a double-edged blade” on that list.
A single-edged sword is not named, but Section 10(b) also contains a catch-all for “a billy or other dangerous weapon” that applies when someone is arrested for an alleged crime or breach of the peace. Official state jury instructions treat straight-bladed weapons as dangerous “per se,” meaning dangerous by design.2Mass.gov. Carrying a Dangerous Weapon When Arrested GL c 269 s 10b The practical effect: an officer who stops you for any reason and finds a sword can treat it as a dangerous weapon under the catch-all.
A dull, unsharpened wall-hanger sits in a gray area. It may not qualify as dangerous per se if it genuinely cannot cut. Sharpen it, and the analysis changes.
Transporting a Sword
If you need to move a sword for a legitimate reason, such as a martial arts class or a historical reenactment, keep it in a fully enclosed, non-transparent carrying case and store it in the trunk or another area of the vehicle out of arm’s reach. That does not make transport explicitly legal, but it reduces the risk of being charged by showing a lack of intent to use the weapon.
Weapons That Are Always Illegal
Some edged weapons are banned from manufacture and sale entirely. Section 12 of Chapter 269 prohibits sword canes, pistol canes, ballistic knives, switch knives with blades over one and a half inches, and knives with detachable blades that can be propelled by a mechanism.3General Court of Massachusetts. Massachusetts General Laws Chapter 269, Section 12 If a sword hides its blade in a cane or walking stick, uses a spring mechanism, or has a detachable launching blade, it falls into a prohibited category regardless of what you do with it.
Buying, Selling, and Shipping
Massachusetts does not require a background check, dealer license, or prior authorization to buy or sell a standard sword. You can purchase one from a retailer, an online store, or a private seller. The restrictions that apply to firearm transactions do not extend to swords.
No state statute sets a minimum age for buying a sword. Some retailers impose an 18-and-over policy as a store practice, and some municipalities may add local restrictions on weapon sales.
Selling a prohibited item like a sword cane carries a fine of $50 to $1,000 or up to six months in jail under Section 12.3General Court of Massachusetts. Massachusetts General Laws Chapter 269, Section 12
Mailing a sword through USPS is allowed if the blade is securely wrapped and enclosed so it cannot injure postal workers. USPS Publication 52 covers knives and sharp instruments, with separate rules restricting switchblade shipments to narrow categories of government and military recipients.4Postal Explorer. Publication 52 – Knives and Sharp Instruments UPS and FedEx set their own packaging rules.
Importing a sword from overseas is permitted by U.S. Customs and Border Protection, though switchblades and spring-loaded knives are seized at the border. CBP advises travelers to check state and local laws at their destination, because federal clearance does not override stricter local rules.5U.S. Customs and Border Protection.

Using a Sword in Self-Defense
Massachusetts recognizes a castle doctrine. Under Chapter 278, Section 8A, if someone unlawfully enters your dwelling and you reasonably believe they are about to inflict serious bodily injury or death on you or anyone else lawfully there, you may use reasonable means to defend yourself, and you have no duty to retreat inside the home.6General Court of Massachusetts. Massachusetts General Laws Chapter 278, Section 8A
“Reasonable means” is the hard limit. A sword is a deadly weapon by nature, so using one against an unarmed intruder who poses no lethal threat would likely be judged disproportionate. Courts evaluate self-defense claims on proportionality, necessity, and whether the belief in danger was objectively reasonable.
Outside the home, the duty to retreat applies before deadly force can be used. Swinging a sword at someone on the street, even if they attacked first, will not be treated the same way as defending yourself inside your home.
Penalties for Sword-Related Offenses
Penalties under Chapter 269, Section 10(b) depend heavily on whether you have a prior felony conviction.
- With no prior felony: a fine of up to $50 or up to two and a half years in a jail or house of correction.
- With a prior felony: a mandatory minimum of two and a half years and up to five years in state prison, or six months to two and a half years in a house of correction, with no fine-only option.
That mandatory minimum for repeat felons is what catches people off guard. Someone with an old felony on record who is arrested carrying a sword faces real prison time even if the sword was being transported peacefully.1General Court of Massachusetts. Massachusetts General Laws Chapter 269, Section 10
If a sword is used to assault someone, the charge becomes assault with a dangerous weapon under Chapter 265, Section 15B, punishable by up to five years in state prison, a fine of up to $1,000, or up to two and a half years in jail. When the victim is sixty or older, a second offense carries a mandatory minimum of two years, with no probation or parole eligibility until one year is served.7General Court of Massachusetts. Massachusetts General Laws Chapter 265, Section 15B
Reckless or negligent use of a sword can also lead to civil lawsuits separate from any criminal case. Intent, the circumstances of possession, and criminal history all shape how courts weigh both.
