Why on your keychain? Check out the cigarette lighter watch.<br>http://www.gizmos-uk.com/LighterWatch.htm<br><br>Just a joke. These were real popular in France in the late 70s when I lived there. It seemed that alot of Frenchmen smoked an awful lot. <br><br>I carry a little half size Bic disposable. It has plenty of flame, is inobtrusive, gets no second looks when I empty my pockets, and is so cheap I don't care if I lose it. Also if it runs out of fuel you can still shoot out sparks.<br><br>
