This is a technique I have read about in the Old Tools Newsgroup, that works
on handsaws. You press the blade against a hard, heavy surface, like the
top of an anvil, so it is held flat. Then, tap gently with a small hammer.
The hammering stresses combine with the flattening stresses to make the
metal yield, so the blade is straightened. For your blade, you might try
holding it with clamps and blocks while you do the pounding.
