WOODBURY - The TSA has announced that airline passengers can start bringing small knives on planes again after April 25.

Officials say knives must be less than 6 centimeters long and less than a half-inch wide.

Other previously banned items like hockey sticks, golf clubs, and ski poles will also be allowed on board. Box cutters and razor blades, however, will still be confiscated.

The TSA says the change is for the convenience of the airline screeners.

The heads of several flight attendants unions are calling the move dangerous.
