A lot of cigar aficionados do not use the ordinary yellow flame lighters because cigar is too delicate to absorb the weird odour from gasoline. So, in the old days, people would use matches and cedar wood pieces to light up a cigar. But the recent twenty years, they love to use torch. The 2000 degree celsius blue flame can fully burn the gasoline without emitting bad smell. Also, the stable blue flame could burn the cigar head evenly without destroying the wrapper.
