IllinoisConditional
Illinois's firearm preemption doesn't cover knives, so home-rule cities regulate them — Chicago bars concealed carry of a knife with a blade over 2.5 inches (Muni. Code 8-24-020).

Minnesota's only weapons-preemption statute, 471.633, covers firearms, ammunition and components only — not knives — so local knife ordinances are not preempted.
