CaliforniaConditional
California has no knife-preemption statute, so cities regulate knives locally — e.g., Los Angeles bars carrying a knife or dagger in plain view in public (LAMC 55.10).

NevadaConditional
Nevada's weapons preemption (NRS 244.364 counties / 268.418 cities) covers only firearms, accessories and ammunition, so cities/counties (e.g., Clark County) may regulate knives.
