[Berkley]

It is not as if swords had been singled out for the purpose. A quick Google search yields this non-inclusive list:

Quantities of illegal drugs crossing the border have been hidden in baby diapers, fresh fruit, frozen fruit pulp, hollowed-out religious statues and other relics, clothing mannequins, electronic equipment, the hulls of ships, panels and gas tanks of cars, bags of coffee, surfboards, books, furniture, concrete fence posts, ice-packed cases of vegetables, aerosol cans, sneakers, and pillows strapped around someone's waist. Heroin and cocaine have been stuffed into condoms and swallowed by couriers; animals have been surgically cut open and, again, had heroin- or cocaine-filled condoms inserted into their bodies, were sewn shut, and were then transported across the border; drugs have been placed in airtight containers in a liquid—such as olive oil, gasoline, liquor, mouthwash, shampoo, and the water tropical fish swim in—and smuggled into the country. Cocaine has been molded into a bust of Jesus and spray-painted a light-gray color; 15 pounds of cocaine were chemically bonded into two fiberglass dog kennels; half a ton of cocaine was packed into hollow plaster shells shaped and painted to look like yams

. It seems unlikely that swords will become a major target for customs inspections.
