Yes, butterfly knives (balisongs) are legal in Idaho as of 2024. Idaho does not classify balisongs as prohibited weapons under state statute, and no municipal ordinances in major cities (Boise, Meridian, Nampa) impose additional restrictions. However, concealed carry laws and age limits for possession apply.
Key Regulations for Butterfly Knives (Balisongs) in Idaho
- No State Prohibition: Idaho Code § 18-3302 does not list balisongs as illegal weapons, distinguishing them from switchblades or gravity knives.
- Age Restrictions: Minors under 18 may possess balisongs only under adult supervision or for lawful purposes (e.g., employment, hunting).
- Concealed Carry: Carrying a balisong concealed (e.g., in a pocket) without a concealed carry permit may violate Idaho’s concealed weapon laws if the knife is deemed a “dangerous weapon.”
Local Considerations: While state law permits balisongs, some Idaho counties (e.g., Kootenai) have historically enforced stricter interpretations of “dangerous weapon” statutes. The Idaho Legislature’s 2026 session may revisit knife legislation, but no pending bills currently target balisongs. Always verify municipal codes, as some cities (e.g., Coeur d’Alene) may enforce additional restrictions.
