An NPR story on this incident stated that the victim was going to resume smoking, "so that he would always have a lighter with him." ???!!! Can't a non-smoker carry a lighter? This one does....
So does this one. However, it's not often than I think to test it, so there's a real chance it will be out of fuel when I need it. A smoker will be "testing" it 20 times a day.
Also, I have been unable to find a good lighter for non-smokers. I carry a pea-style one, but (a) there's no way to see how much fuel is left, and (b) the fuel still evaporates, albeit slowly. Also, it's quite small and fiddly, and would be hard to use if my hands were cold (ie, when I most need it). I'd rather a butane lighter with a fuel window. However, the ones I've found have been too bulky, or too unreliable, or missing the fuel window. I'm not sure I'd trust a piezo ignition when wet, and I don't want an exposed grind-wheel that would trash other items in my pocket.
