I had used the blunt end of a punch/drift, but I misplaced it, so instead I tried a tire-iron… Bingo! I slip the wedged end of the iron into the neck of the bottle until it reaches the bottom’s inner edge. Then, while holding the tire-iron handle, gently tap the bottom, and Voilà! a glass medallion for knapping pops off.

It is similar to how the ancient cultures used their stone knives.
To break the bottoms out of the bottles I put a bolt or drill bit in the bottle and place my thumb over the hole in the neck and shake the bottle up and down. It usually will break the bottom out intact.
