The safest utility knives are those equipped with auto-retracting mechanisms and ceramic "finger-friendly" blades. Because they require the user to hold down a slider to expose the blade, they automatically snap back inside as soon as you lose contact with the cutting surface, completely preventing accidental lacerations.

You can absolutely bring a utility knife in your checked baggage, but it is strictly prohibited in carry-on bags. To ensure smooth screening and prevent injury to baggage handlers, wrap the blade securely or place it in a hard sheath before packing it into your luggage.
