No thoughts on this one guys?
Wow, you expect a quick response! :-)
I have a Blazer blue-flame lighter. Advantages are more heat, longer and more directable flame, and somewhat (not completely) windproof. And it looks cool.
Great for lighting candles (longer directable flame), and I've also used mine for de-icing a bike lock, and heating up a metal candle holder to melt the broken-off candle stump in order to insert a new candle. The latter wasn't exactly a survival situation, but I'd be generally more confident in its ability to light a fire under difficult conditions than a bic.
It's also easier to use for sealing the ends of cut paracord, and I'd bet that it'd be better for burning through ropes (if you're minus a knife.)
