Glad I'm not the only one that doesn't feel right without one on me. When I fly, they sit in an outer compartment in my checked baggage and go straight into the pockets as soon as the bags are claimed. I tend to over do it and carry two with me most of the time, whatever small cheap folder I grab that morning and a swiss army knife knock off with a little LED flashlight as one of the tools. Not sure what the make is, it was a Christmas gift a couple years back, but the little light is nice and the LED bulb means it will last a while. Along with the knives I've always got a flashlight in my back left pocket. Most people laugh if I ever pull it out but its come in handy more than enough times to make it worthwhile to carry. I tend to adhere to the two is one, one is none philosophy. Most say it's overkill, I just prefer to be prepared.
