If it hits 0, it's gone for good. The game has a safety net in that if a sword takes lethal damage from full HP, they'll only be reduced to 1HP and will be unable to fight or be attacked for the rest of the battle. Afterwards, you will need to head back to the citadel to repair, otherwise they will definitely break at the next battle.
