I was using my chisel today with a mallet and noticed a curve in the blade of it. It is a 1” Ashley isles, which has a pretty thin blade, so I’m pretty sure I just overdid it when removing material. It is a fairly continuous curve and not very much - slight enough that I’d have trouble photographing it.

Any advice/experience with straightening a curved chisel blade?

I held it with about 1” on the edge of the bench and tapped the back with a mallet. That might have made a small improvement. Looking online I’ve also seen recommendations to clamp the blade and bend it by hand.
