Real-World Scenarios: Butterfly Knives in Kentucky

Can You Fly With Butterfly Knives Out of Kentucky?

Butterfly Knives may be legal in Kentucky, but airports are federal territory. TSA screens under federal rules, not state law. If the item is federally restricted, expect problems at the checkpoint. Even if it clears TSA, the laws of your destination state apply the moment you land. Plenty of travelers have learned this the hard way — legal when they packed, criminal when they arrived.
