Mine was examined several time on my trip to Egypt, including at the Cairo airport on the way home. They were so focused on it neither they - nor I - realized that I also had a titanium dive knife, a large Z-knife, and a pair of trauma sheers in the same carry-on bag.
About halfway through the 10-hr flight I was rummaging through the bag to get something out and found them in a Miflex dry-bag tucked in a pocket.
Yikes!
