Knife ownership and open carry are broadly legal in Maine, but significant restrictions apply to concealed carry—especially for knives considered “dangerous or deadly weapons” such as dirks, stilettos, and Bowie knives.
What Knives Are Legal in Maine
Most types of knives—including pocket knives, automatic knives, balisongs, and gravity knives—are legal to own and openly carry. Switchblade and automatic knife prohibitions were repealed in 2015, so these types are no longer restricted. However, knives explicitly intended or typically used for offensive or defensive purposes (dirk, stiletto, Bowie knife, etc.) are subject to special regulations.
Concealed Carry Restrictions
It is illegal to carry concealed any knife defined as a “dangerous or deadly weapon usually employed in attack or defense of a person”—specifically dirks, stilettos, Bowie knives, and similar types. Maine law does not specify a minimum blade length for these restrictions. Open carry of these knives is permitted, provided they are not displayed in a threatening manner.
Location-Based Bans
Knives are prohibited in certain places, including court facilities and schools. Local ordinances in cities like Augusta, Bangor, and Lewiston may add further restrictions, so checking relevant local regulations is advised before carrying a knife in public places.
Hunting, Fishing, and Trapping Exception
The concealed carry prohibition does not apply to knives used for hunting, fishing, or trapping while engaged in those activities. This exemption recognizes Maine’s strong outdoors culture and is precisely described in state statutes.
Penalties for Violations
Violating Maine’s knife laws—such as unlawfully carrying a restricted knife concealed—can result in penalties ranging from fines to imprisonment. Concealed carry of a restricted knife is classified as a Class D crime, subject to up to one year in jail and up to $2,000 in fines.
Law Enforcement and Military
Members of law enforcement and military may be exempt from certain restrictions while performing official duties, but for ordinary residents and visitors, the same prohibitions apply.
