I also recommend the Spydercard, mine stays in my wallet at all times. The SOG Access card looks nice, but the clip makes it more bulkier than the Spydercard. Even if you removed the clip, you would still have the switch protruding. This leads me to believe that it won't truly fit well into a standard wallet.<br><br>Amper has a good point, a wallet-carry knife has never been detected in any search i've ever encountered. I have always made a habit of placing my wallet in the personal effects bin at the airport, even before I had the knife in there...they are none the wiser.<br><br>John McIntire
