Pocket knives are generally legal to own and carry in Maine, with open carry unrestricted and concealed carry permitted for everyday folding models not deemed “dangerous weapons.” Key restrictions under 25 M.R.S.A. §2001-A target specific offensive knives like bowies or dirks, but standard pocket knives escape these.
Pocket Knives Defined
Pocket knives typically mean folding knives with blades under 4 inches, designed for utility like cutting boxes or preparing food. Maine law avoids blade length limits, focusing instead on intent and design.
Statewide Legality
Ownership of any knife, including pocket knives, faces no bans; automatic knives (switchblades) legalized since 2015. Open carry is fully legal statewide without restrictions.
Concealed Carry Rules
Concealed carry is prohibited for bowie knives, dirks, stilettos, or “other dangerous or deadly weapon usually employed in the attack on or defense of a person.” Everyday pocket knives qualify as non-offensive and may be concealed; hunting/fishing knives explicitly exempt.
Courts assess via fact-specific inquiry: design for human harm, primary attack/defense function, or modifications.​
Local Variations
No statewide preemption means cities like Augusta, Bangor, or Lewiston may add rules—check ordinances for stricter limits.
Restricted Locations
Age Restrictions
Minors under 18 generally cannot carry “dangerous” knives publicly without purpose like hunting; pocket knives may require supervision. Adults 18+ face standard rules.
Penalties for Violations
Violations of §2001-A are Class D crimes: up to 1 year jail, $2,000 fine. Threatening display elevates to criminal threatening (§209).
Best Practices
Carry utility-focused pocket knives openly or concealed in pockets/backpacks; avoid “tactical” looks in urban areas. For outdoors, hunting exemptions broaden options. Consult local police for city specifics or recent changes.
