Someone (my old dad) borrowed my riding mower and returned it with the blade tips severely bent. Instead of the blades being horizontal, the the tips now curl downwards at a 30~45 degree angle. I have an oxy/acet torch. Can I heat up the tips and straighten out the blade without weakening the tip? I also happen to have a 5 gallon bucket of used oil sitting next to the table vice that I'd use to hold the blade while it's being straightened. Should I quench the hot straight blade in the oil after working on it? Thanks, I know very very little about blacksmithing.
