Is Butterfly Knives (Balisongs) Legal in Hawaii After the 2026 Framework Overhaul?

No, butterfly knives (balisongs) are prohibited in Hawaii under state law. Possession, manufacture, or sale of balisongs is illegal, with no exceptions for collectors or ceremonial use. Violations may result in felony charges under Hawaii Revised Statutes § 134-51. Local law enforcement enforces these restrictions strictly, and recent 2026 legislative proposals aim to further tighten penalties.

Key Regulations for Butterfly Knives (Balisongs) in Hawaii

  • Prohibition under HRS § 134-51: Balisongs are classified as “switchblades,” which are explicitly banned. Possession or transfer constitutes a felony, punishable by up to five years imprisonment or fines up to $10,000.
  • No Exemptions for Collectors: Unlike some states, Hawaii does not permit ownership of balisongs for historical or display purposes. The law applies uniformly to all individuals, including licensed dealers.
  • Enforcement by DLNR and County Police: The Department of Land and Natural Resources (DLNR) and local police departments conduct routine inspections, particularly at ports of entry and during firearm-related compliance checks. Recent 2026 budget allocations prioritize balisong interdiction efforts.
