Transportation Security Administration screeners stopped a woman at the Honolulu Airport after a 3-inch pocketknife was discovered concealed in her bra, the TSA said in a blog post.

The TSA said the knife was discovered after the woman went through a metal detector earlier this week.

The blog post noted that it is important for travelers to examine their bags to ensure no prohibited items are inside and cited the Honolulu incident as an example of items found “in the strangest places.”

 Also this week, TSA screeners found a box cutter blade in a passenger’s shoe in Salt Lake City; a 17.5 inch sword inside the cane of a Laredo, Texas passenger, a lipstick knife in San Antonio and a credit card knife in Albuquerque.
