The TSA is making the changes to conform with international standards, agency chief John Pistole said today during a security conference in New York.
Pistole also wants to free up TSA screeners.
In the last three months of 2012 alone, screeners at Los Angeles International Airport seized 47 of the small knives each day, according to Air Transportation World.
“Frankly, I don’t want TSA agents to be delayed by these,” Pistole said.

The Flight Attendants Union Coalition, representing nearly 90,000 attendants nationwide, blasted the decision.
Stacy Martin, president of Southwest Airlines' flight-attendants union, called it "outrageous."
"This policy was designed to make the lives of TSA staff easier, but not make flights safer," she said in a statement obtained by Fox News. "While we agree that a passenger wielding a small knife or swinging a golf club or hockey stick poses less of a threat to the pilot locked in the cockpit, these are real threats to passengers and flight attendants in the passenger cabin."
