It goes back to the manufacturer and gets honed with a diamond lap.
But they typically break before they dull so the manufacturer isn't
called upon to redress too many... and most likely they simply send a
new one and discard your dulled one, that remedy costs less because
the company who sold it very likely would need to send it back to the
manufacturer and they are probably in China.
