-Empty Bic Lighter
It's not to uncommon to see empty bic lighters on the ground all over the place. Snag em, for one thing you are pickin up litter so good on you and you are savin money on flints, all round good deal.
Step 1: Startin
Then you will have to chop the flint in half with a small saw blade so that It is no longer too long to install.
Step 2: Finishin
BTW I don't smoke, just like Zippos
Good luck, hope she helped!
