Well, you make a good point about the Classic availability and price, although I have noted that locally, some Targets have discontinued carrying any pocket knives at all. I hope that is not a growing trend.
Meanwhile, I must confess that the Bic trick, which seems to work for all my friends, including the non-smokers, has eluded me. I can't shake the feeling that behind my back, everyone points at me and snickers, "What a numbskull." Actually, over the years I have tried several ways to open beer bottle with field expedient methods, but they usually turned out kind of messy. Most of the world may not really need one, but I must have a dedicated cap lifter because otherwise I can't stand the humiliation.
There's a ton of videos on Y-tube about opening beers without a bottle opener. Once you get the basic technique mastered, it's a sense of liberation, of freedom. You realize that for the rest of your life, you don't need THE TOOL. You're free of the constraint. No matter if it's a Bic lighter, a stick, a spoon, a house key, or even a folded up dollar bill. You can truthfully say " Bottle opener? We don't need no steenkin bottle opener!"
And mean it.
Carl.
