I've now got my 2 chisels straighened out. I had to use a combination of hydraulic press (and being careful) and peening. Then when I was satisfied when holding up my combination square straight edge, I started lapping them on plate glass with wet/dry paper starting at 180 grit. It takes a long time to take a couple thousanths off. I got my 1.5 inch chisel where I want it, but am still working on my 2 inch chisel. I'm hoping that with normal use and care, my chisels won't deflect or lose the straighness that I've now got them to. I would think that mallet blows should not be enough to do this. There should be enough spring back in the chisel as well.
