Knives with locking blades and moulded handles are still banned from US planes, the US Transportation Security Administration told NBC News.
The change will take effect on 25 April.
Luggage Items permitted for the first time since 9/11 are:
- Knives that do not lock, are 2.36ins (6cm) or less in length and below 1/2in wide
- Novelty-sized and toy bats (including for baseball)
- Billiard cues and ski poles
- Hockey and lacrosse sticks
- Up to two golf clubs
Overseas passengers will no longer have to check their knives as they pass through the US, according to Bloomberg News.
