It depends on the level of cigar snobbery that one subscribes to. Butane is a bastard gas but it's a clean flame, like sweet lady propane. If you use a Zippo you are likely to taste whatever fuel is in it when you light the cigar. Wooden matches and cedar strips are fine if you like to show off your cigar smoking pedigree. Bernzomatic works great too and is a wicked fast light.I thought cigars are lit with the cedar paper that separates levels of cigars in a box
