Beginning in late April pocket knives will be allowed on aircrafts once again.
The new legal size will be 2.6 by 0.5 inch blades, as long as knives are stored in carry-on luggage.
Along with knives, things like golf clubs, pool cues and even lacrosse or hockey sticks will be allowed on board as well.
Flight attendant unions are livid.
"It's going to create passenger confusion. It makes no sense to bring a weapon on board," one flight attendant said.
The Transportation Security Administration said that tons of things like pocket knives that are confiscated each month slow down passenger lines.
They also said that small blades don't pose as much of a threat anymore, and that finding them takes screeners away from finding major threats like liquid explosives.
Barry Segal, in Nashville for business, was headed back home to Israel when he spoke to Nashville's News 2.
"Especially coming from a country like Israel where security is the highest priority, people can bring on a baseball bat…" Segal said.
The new legal size for a baseball bat will be 24 inches or less, the size of a souvenir bat.
Traveler Krista Ashton said that she hopes people will remain respectful once the ban is lifted.
"If these are pulled out on an aircraft, a pocket knife or something like that, it can scare others, so just be aware that yes, it's you traveling, but you are on a place with multiple people," she said.
Details on the new rules will be announced April 25.
