I used to use a lighter until I broke down and bought an electric
bench torch lighter.
I think the concern here is the notion, true or not, that the
lighter can explode in your hand. I was always told to cut the
bottom off an empty lighter then just use the striker that is built
into it to light a torch. Clearly,whether the explosion hypothesis
is true or not, it is safe to use the little striker from a lighter.
I, too, broke down and got myself the little piezo-electric lighter.
I, too, love it.
Some years back, I thought it would be clever to just keep a lit
candle on my bench for quick light-ups. The first use, the whoosh of
flame as the gas lit melted about an inch of candle, leaving a
large, droopy, flaming wick, and a puddle of wax. Oh, well, back to
the drawing board.
