The left saw has two kinks, but most of the rust is sanding off pretty well with 220 grit. The right one has a slight bend but no sharp kinks, though it has a fair amount of pitting that's deeper than sandpaper is taking off. I'll probably continue to restore the right one, but curious if folks think they wouldn't be functional.
How do they cut? I'd personally start with filing and setting the teeth and straightening, then if they work worry about getting them looking nice.
