On Tuesday, a man tried to take a ninja book with knives hidden inside onto a plane at Reagan National Airport. According to the Transportation Security Administration, that incident is just one of many.
Increasingly, officials see some are getting more creative than ever when they hide banned items.
Items as tiny as a concealed blade and as big as a butcher knife are just a small sample of what's been confiscated at security checkpoints at Reagan and across the country, according to TSA.
Often, deadly weapons are masked as everyday items, like a cane than can be pulled out to reveal a sword or a stun gun disguised as a pink Blackberry--the call button says "stun."
"I'm amazed at the technical ways that different people use to scam the airports and everyone else," said traveler John Champlain.
Recently, a man tried to travel with 13 knives in his bag at Baltimore Washington International Airport. He was arrested.
TSA officials cannot give specifics on how many weapons are recovered from each airport, but say about 5 million banned items are confiscated a year.
Officials attribute increased security, like the controversial pat-downs and body scanners, to the crack-down on weapon smuggling.
"Every single day our officers are stopping deadly weapons at this airport and airports across the country from getting from one side of the checkpoint to the other," said TSA spokesman Kawika Riley.
Even though it may take longer than ever to get through security, passengers say Tuesday's incident is a good reminder of why it's worth it.
"It is a reminder of how important it really is," said traveler Develyn McDonald.
