Yeah, that definitely looks odd in the picture. So it's not perfectly flat on that left side? If it was flat on that side then I would say it's a flaw in the distal taper on the right side grind. If it's actually bent, then maybe someone dropped it and it actually bent instead of snapping off. I don't know enough about super blue, but maybe it's a fairly tough steel and not brittle.
In any case, it adds character to your knife and still works hey? Hope it doesn't drive you nuts in the long run. Maybe Sal will know if it can be safely fixed without breaking it.
