Here’s a source on doing it:
http://woodcentral.com/articles/handtools/articles_866.shtml

And here’s the same article with some more discussion:
http://www.sawmillcreek.org/showthread.php?63325-Straightening-Bent-Handsaw-Blades&highlight=straightening%20saws

Short version is it depends on whether it is a kink or a more gentle bend. Kinks can’t be entirely fixed and require a hammer and anvil to do much of anything with. Gentle bends can be mostly fixed by careful bending in some cases, but to properly fix them require re-tensioning with a hammer and anvil. As I recall, Bob Smalser’s article linked above covers mostly the hammering method.

Good news is a Warranted Superior probably isn’t a valuable saw so it’s a fine one to start practicing on. The hammering method is the right way, but can also damage the saw if you’re not good at it. Instead you can first try bending it back by curling it into a circle, then try just a bit smaller circle as needed to get the bend out. You can also use three dowels and a vice and place two on one side of a bend and the third on the other side on top of the bend and close the vice as needed to reverse the bend. Takes some practice.

Above all, have fun.

Whatever you do, NEVER try to apply heat to a saw blade. Heat will anneal the steel and you will be able to bend it into a pretzel.

Thanks. A little heat had crossed my mind but on a thin blade I didn’t think this was a good choice
