Two weeks ago went into Chicago Ohare Continental Airlines President Club. Wonderful staff, good drinks and real knives. What? Yes, metal knives. I asked front desk why the were allowed to have metal knives in lounge. She stated, TSA said it was ok. Guarantee you this, if I walked through security with a metal knife on my person, I'd be wishin I hadn't. Oh, the lounge is AFTER the Xray/metal detector/searching area. It is in the "secure" area of the airport. Guess TSA trusts the members of PC to leave the knives in the lounge. Havent seen metal knives in any other lounge for long time.
