Bummer but not the end of the world.
It looks like a heel side skidded turn has hit something just behind the edge tines (obvious by the base damage) which has pushed the edge out and possibly up aswell, cant make it out in the pics.
I would straight edge it and mark it with a marker to see how much material will be lost if you file it back to straight, if its half or less file it back.
On another note is there a thread on these boards somewhere? I would like to hear your impressions.
