i took a hairdryer when i had a blade hitting the scale. worked just fine for me.

apply heat to the area where you wanna bend it back. once its warm put tension on it so it is straight, and keep this grip and fast rens it under cold water. repeat 2-3 times.

i had not read about it but i just tested it and it did work for me. might aswell work for you if your lucky. if you have a razor/scales you dont care much for try on that first so you get a feeling of it.
