The agency will permit knives with retractable blades shorter than 6 centimeters (2.4 inches) and narrower than 1/2 inch at the widest point, TSA Administrator John Pistole said today at an aviation security conference in Brooklyn.
This is one of the best things that the TSA has done. Now I just need to find the perfect travel knife that conforms to those rules. Also, in case you were worried, sounds like whiffle ball bats are going to be allowed too.
Wait, why were whiffle ball bats banned? Oh, right, TSA.
