The TSA's requirement that all travelers take off their shoes before going through the metal detector or "nude" body scanners yielded a surprising find earlier this month, when a small knife was discovered inside the sole of a shoe.
The 3 1/2-inch double edged knife was found on February 15, at San Diego International Airport, according to the TSA Blog.
