Maine’s legal landscape regarding pocket knives is generally permissive, but there are important restrictions and nuances to be aware of.
Ownership and Possession
Most pocket knives are legal to own and possess. This includes folding knives, utility knives, hunting knives, and even automatic knives (commonly called switchblades), as the prohibition on automatic knives was repealed in 2015.
There are no statewide restrictions on blade length for pocket knives. The law does not specify a maximum blade length for knives carried either openly or concealed, with one exception: gravity knives or switchblades carried by one-armed individuals must have a blade shorter than three inches.
Bowie knives, dirks, stilettos, and similar weapons are legal to own but are subject to carry restrictions. These knives are not outright banned, but their concealed carry is prohibited.
Carry Regulations
Open Carry
Permitted: Open carry of knives is generally allowed throughout Maine, including pocket knives and most other types.
Restrictions: Displaying a knife in a threatening manner is prohibited and can result in criminal charges. This applies to all knives, not just those considered dangerous or deadly.
Concealed Carry
Restricted for certain knives: Concealed carry of “bowie knife, dirk, stiletto, or other dangerous or deadly weapon usually employed in the attack on or defense of a person” is illegal.
Permitted for most pocket knives: Ordinary pocket knives and utility knives not designed for attack or defense may be carried concealed.
Exceptions: Knives used for hunting, fishing, or trapping may be carried concealed, regardless of type, as long as they are used for those purposes.
Prohibited Locations and Local Ordinances
Statewide Restrictions
Schools: Knives are generally prohibited on school premises under district rules.
Court Facilities: Carrying knives in court facilities is prohibited by judicial order.
Local Laws
No statewide preemption: Local governments (e.g., Augusta, Bangor, Lewiston) may enact their own knife laws, so individuals must check local ordinances for additional restrictions.
Penalties
Concealed carry of restricted knives: A Class D crime, punishable by up to one year in county jail and a fine of up to $2,000.
Threatening display of a knife: Also a Class D crime, with similar penalties.
