Yes, butterfly knives (balisongs) are legal in Utah for individuals aged 18 or older under state law, but local ordinances and concealed carry restrictions may apply. Utah’s Uniform Firearm Laws do not explicitly ban balisongs, yet cities like Salt Lake City impose additional regulations on blade length and carry methods. The Utah Bureau of Criminal Identification (BCI) has not issued recent advisories on balisongs, though enforcement varies by jurisdiction.
Key Regulations for Butterfly Knives (Balisongs) in Utah
- Age Restriction: Possession or sale is prohibited for individuals under 18, aligning with Utah’s general knife laws under Utah Code § 76-10-501.
- Blade Length Limits: While no statewide restriction exists, Salt Lake City and Provo cap blade lengths at 3.5 inches for concealed carry, per municipal ordinances.
- Concealed Carry Prohibitions: Balisongs may not be carried concealed in public without a valid concealed carry permit, per Utah Code § 53-5-704, as they are classified as “dangerous weapons” under state interpretation.
Local law enforcement agencies, including the Salt Lake City Police Department, have discretion in enforcing these rules, particularly in public spaces or during heightened security alerts. The Utah Legislature’s 2023 session did not amend balisong-specific statutes, leaving municipal bodies to interpret existing laws. Retailers must verify compliance with local ordinances, as penalties for violations can include fines up to $750 under Utah Code § 10-8-60.
