Is Switchblades Legal in Colorado After the 2026 Policy Reforms?

Yes, switchblades are legal in Colorado with specific restrictions under state law and local ordinances. State statute permits switchblades with blades under 3.5 inches, while local jurisdictions like Denver and Boulder impose additional bans. Recent 2026 compliance guidance from the Colorado Bureau of Investigation (CBI) emphasizes blade-length enforcement and concealed carry prohibitions.

Key Regulations for Switchblades in Colorado

  • Blade Length Limit: State law (C.R.S. § 18-12-101) allows switchblades with blades shorter than 3.5 inches; longer blades are classified as illegal weapons.
  • Local Prohibitions: Municipalities such as Denver (Code § 38-117) and Boulder (Municipal Code § 5-2-10) ban all switchblades regardless of blade length, creating patchwork compliance requirements.
  • Concealed Carry Restrictions: CBI guidance (2026) clarifies that carrying a switchblade concealed—even if legal under state length—may violate concealed carry laws if deemed a “dangerous weapon” under C.R.S. § 18-12-102.

Federal regulations under the Switchblade Knife Act (15 U.S.C. § 1244) do not preempt Colorado’s stricter local rules. Violations may result in misdemeanor charges, with penalties escalating under municipal ordinances. Businesses importing or selling switchblades must verify compliance with both state and local authorities to avoid 2026 enforcement actions.
