Today was my first carry on with DE on an airline. I packed my slant and one Astra blade (in the Astra cardboard box). They tore apart my luggage and the TSA screener took my slant from my kit and looked to see if there was a blade in it. There wasn't so they said I was good to go. They missed the blade altogether. I mentioned that I checked the TSA web site and DE blades are allowed and she was totally unaware. Feeling lucky that I got through with my blade so I can be BBS for my business meetings.
