All I know is that I miss my Zippo. Maybe I should have bought it in safety orange too, because mine was camo, and I probably dropped it in the woods somewhere...
I've had the cheaper variations of those pressure lighters. They ran out too fast for my taste. However, the somewhat larger mini-torches are handy if you use blue lock-tite on your guns or scope mounts. You can snug up the screws nice and tight, and when you want to loosen them up, you just hit the screw with the flame for a second or two.
