For 12 years airport security has had a sharp objection to tiny pocket knives, but now they don't see the point.
"I don't know if that's a good thing or a bad thing," said Seth Kelson, passenger at Salt Lake City Airport.
"I don't really agree with it," said Erised Ortiz, passenger at the Salt Lake Airport.
"I don't really have a problem with that," said Kathy Jerry, passenger at the Salt Lake Airport.
The Transportation Security Administration is now saying it's okay to carry small knives on a plane as long as the blade is less than 2.36 inches long, and less than half an inch wide.
"We know that these small little items are unlikely to be used again to hijack an airplane," said Jeff Price, Professor, Metropolitan State University of Denver.
Also now allowed are golf clubs, pool cues, and lacrosse and hockey sticks. A spokesperson for flight attendants doesn't like it.
"Having knives on board is a horrible decision and we're incredibly disappointed with TSA for allowing weapons on planes," said Veda Shook, International President of the Assoc. of Flight Attendants.
When Reporter Brian Carlson explained it to passengers at the Salt Lake Airport they didn't get it.
"You can bring a knife, but you can't bring toothpaste? It's ridiculous!" said Sue Roukema, passenger at the Salt Lake Airport.
"If you can have a knife, I should be able to keep my hair gel," said Kelson.
According to TSA, they have bigger things to worry about like guns and liquid explosives. They anticipate relaxing the rule on knives will reduce checkpoint delays.
For many people Carlson talked to Thursday night, that rationale didn't sit well.
"That might be convenient for them but they should put safety first," said Greg Roukema, passenger at the Salt Lake Airport.
"I would stand in line a long time if it makes the plane safer," said Jerry.
"If they've been getting rid of it for as long as they have, they might as well keep it up," said Ortiz.
When TSA talks about bigger problems like guns, the Salt Lake Airport has seen its fair share. Back in February the Salt Lake Airport told ABC 4 TSA workers found 10 guns in less than four months.
