It would have to be the only blade out of line, or a weak blade.
The chinese metals do not have the same quality control that US metals manufacturers have.
There doesn't seem to be the required damage to that blade for it to bend like that from an edge only impact? It is folded nearly neatly in half...or is that a slightly bent tip on the adjacent blade (to the left)?
If so then George's theory is plausible and two blades made contact first with the radiator, the weaker blade bending...still weird...
