But I think even after you boil the blades you would have to wrap the boiled one aruond a new one to get the shape back. If not, wouldnt it be flat?
I don't think so.... it just takes out the twist somehow. It looks like he boiled them for a minute. I've never had tweaked blades, so I've never tried it.
