For the first time since the 9/11 terrorist attacks, leaders with the Transportation Security Administration will soon begin allowing small knives and other previously prohibited items on airplanes.
"This is part of an overall risk-based security approach, which allows transportation security officers to better focus their efforts on finding higher-threat items, such as explosives," TSA spokesman John Allen said in a prepared statement.
The new regulations are also an effort to align more closely with International Civil Aviation Organization standards, he also said.
Effective April 25, TSA will allow:
—Knives that do not lock and have blades that are 2.36 inches or 6 centimeters or less in length and are less than 1/2 an inch in width
—Novelty-sized and toy bats
—Two golf clubs as part of carry-on baggage
