The Law in Detail

Key statutes: Wyo. Stat. §§6-8-104, 6-8-103, 6-1-104

Wyoming has no knife-specific statutes; the word "knife" does not appear in the relevant law, so regulation runs entirely through the "deadly weapon" definition in §6-1-104. A first concealed carry offense under §6-8-104 is a misdemeanor with up to a $750 fine and 6 months in jail, while possession with unlawful intent under §6-8-103 carries up to 5 years. Statewide preemption under §6-8-401 blocks local weapon regulation.
