Our household has gone through something like a dozen long-nose lighters. The Bics are the strongest and most reliable of the bunch. DW likes them for lighting candles and the wood stove. I used an empty one to light an old propane barbecue for a couple of years; it sparked every time. Great for starting camp stoves too.

I'm not convinced it holds more fuel than a standard Bic. I can't find any hard info to confirm that suspicion.

For a PSK, though, I think ironraven is right in advising caution. If the nozzle gets mangled or badly rusted, it may fail to light. A standard Bic is far more robust, and you can carry five of them for the same price/weight/size as a long-nose job.

My two-cents' worth.
