Swords won't break from medium damage.

However swords can break even if they are not 1 HP, so long as you go into another battle with a sword in heavy damage. For example if you finish the battle with one sword entering heavy damage (let's say 5 / 30 HP), there is a chance they will break in the next battle if you enter into a new battle. This could occur at long range phase, or if they get attacked by enemy sword. If you are lucky, they will not break if they do not sustain any damage.
