But on Tuesday night at Baltimore Washington International Airport, TSA agents stumbled across one particularly brazen traveler.
Inside the man’s carry-on bag, agents allegedly unearthed a trove of 24 potential weapons, including: Three rope cutters with straight-edged blades, one hatchet, two smoke grenades, 12 bottle rockets, one folding saw, one fixed-blade knife, one credit card knife, one utility knife and two folding knives.
“An unusual assortment of prohibited items were detected by TSA officers at BWI Airport [Tuesday],” TSA spokesperson Lisa Farbstein said in an statement.
The 21-year-old –- who says he was headed to a camping trip –- was detained and interviewed by police and charged for the 14 incinerate devices, TSA said.
He re-packed the knives and hatchets in his checked luggage, TSA said.
This isn’t the first bizarre piece of contraband TSA has confiscated.
Last week, a passenger attempted to pass through security with a knife disguised inside a plastic purple comb.
In the past year, they’ve confiscated several grenades, guns, an assortment of throwing stars, and this terrifying “punching device.”
