I typically do scale straighting as a part of a restoration job. I suspect the razor was exposed to heat at one time which caused the warp. I recently resorted a new razor for a local shop. Somebody had left the razor in direct sunlight and they were writing it off as a lose. I straightened the scales and honed it for shave ready. So it can be done without any problem. But your right. It's not a task for the faint at heart.
