Yes, butterfly knives (balisongs) are legal in Pennsylvania for individuals aged 18 or older, provided they are not carried with intent to use unlawfully. Recent 2026 amendments to the Uniform Firearms Act expanded concealed carry regulations but did not classify balisongs as prohibited weapons. However, local municipalities like Philadelphia retain stricter ordinances, requiring compliance with both state and municipal laws.
Key Regulations for Butterfly Knives (Balisongs) in Pennsylvania
- Age Restriction: Possession is lawful only for individuals 18 years or older, aligning with Pennsylvania’s general knife ownership statutes.
- Local Ordinances: Philadelphia prohibits the sale, possession, or carrying of balisongs without a valid permit, enforced by the Philadelphia Police Department’s Special Investigations Unit.
- Intent-Based Prohibition: Carrying a balisong with intent to employ it unlawfully may result in charges under Pennsylvania’s aggravated assault or disorderly conduct statutes, per 18 Pa. C.S. § 908.
The Pennsylvania State Police Bureau of Records and Identification maintains updated compliance guidelines, particularly regarding recent 2026 legislative shifts. Failure to adhere to municipal restrictions—such as Philadelphia’s outright ban—may lead to fines or confiscation under local public safety codes. Always verify county-specific regulations before possession or transport.
