Transportation Security Administration Chief John Pistole, is sticking by his decision to let passengers carry knives, with blades no longer than 2.36 inches and no wider than a half-inch, back on planes.
But how do passengers feel about this?
We talked to some passengers at Cheyenne Regional Airport to get their feelings on the decision.
"I don't feel that my security's in danger at all by them allowing certain objects on planes. So certain knives, golf clubs, I'd be okay with," said Blake Knadler.
"No, it won't affect anything. If I have to fly, I'm going to fly. Safest way of travel I think," said Joseph Gregorio.
"It takes a six inch or greater blade to penetrate to the heart so beyond that you've got a pretty good chance if it comes to that. I'm a prior service Marine Corps so I have a bit of an understanding what we're talking about there," said Lee Sampson.
The new regulations, set to go into effect April 25, would also allow passengers to bring items such as hockey sticks, golf clubs and pool cues aboard planes.
Pistole says small knives are not a serious risk and this decision will allow TSA to focus on greater threats.
Passengers we spoke to didn't necessarily think that will help security.
"To me it doesn't matter one way or another. If they want to do something they're going to do it and that's how I look at it. I don't think a knife should be allowed, but if guys want to do something to an aircraft they're going to find a way," Gregorio said.
"I feel if they have a plan to get a device on the plane that's going to cause more damage than a knife, they'll find a way and I don't believe that them changing the rules of allowing knives or certain blunt objects on the plane is going to change that," Knadler said.
"I don't have a problem with them. I would rather have my pocket knife on me at all times. I feel naked without one right now, so I think it's a wonderful thing. I don't see a problem with it," Sampson said.
