Yes, butterfly knives (balisongs) are legal to own and carry in Colorado as of 2024, but local jurisdictions may impose restrictions. Colorado law does not classify balisongs as prohibited weapons, unlike fixed-blade knives or switchblades. However, Denver County and other municipalities may regulate their concealed carry under municipal ordinances. Recent legislative discussions in 2023-2024 suggest potential statewide preemption efforts, but no changes have been enacted yet.
Key Regulations for Butterfly Knives (Balisongs) in Colorado
- State-Level Legality: Colorado Revised Statutes § 18-12-102 does not list balisongs as illegal weapons, permitting ownership and open carry statewide.
- Municipal Restrictions: Denver County Code § 38-118 prohibits carrying concealed balisongs without a permit, while other cities like Boulder may impose similar rules.
- School Zones & Government Buildings: Federal and state laws (e.g., 18 U.S.C. § 930) prohibit carrying any knife in secured areas, including schools and courthouses, regardless of blade type.
Enforcement Note: Law enforcement agencies in Colorado prioritize intent-based assessments under § 18-12-105. While balisongs are not inherently illegal, their use in a threatening manner may lead to charges under assault or menacing statutes. Always verify local ordinances before carrying, as municipal regulations can supersede state law.
