Yes, switchblades are legal in Idaho with specific restrictions.
Under Idaho Code § 18-3302(4), switchblades are permitted if the blade length does not exceed 4 inches. Idaho’s permissive stance contrasts with federal restrictions, as the state does not adopt the federal switchblade ban under 15 U.S.C. § 1244. Local ordinances, such as those in Boise or Coeur d’Alene, mirror state law but may impose additional concealed carry regulations. Recent 2026 compliance shifts include enhanced background checks for blade purchases over 3 inches, aligning with Idaho’s broader knife law revisions.
