TSA failed to find a SAK in my jacket pocket on a recent trip. I grabbed my softshell and stuffed it into my carry-on (Camelbak BFM) before a recent trip. When I pulled out my jacket in Houston I felt something heavy in a pocket... sure enough, one of my SAKs! It flew home in my checked bagage!

Now, this isn't as big of a deal as explosives/hazardous materials; I highly doubt if a few people with box cutters will ever succeed in hijacking an airliner again. Technology is only as good as the operator utilizing it. Reliable, alert, intelegent poeple are who will prevent another attack...
