Actually my wife only uses the Zippo to light her cigarettes.
We use matches for the candles and the wood stove and the wood furnace. Nearly every day. Unless we have a bed of coals to work with. Then we add some tinder, and thin cut wood strips to start.
A Bic or a Zippo gets hot, burns the user (believe me, I know via personal experience), and the fuel does not last long, especially in a non-perfect environment, like when it has been raining all day, or in the snow.
That is when matches and your own tinder, or wax based fire starters come in handy.
