A Dremel with a cutoff wheel will make quick work of removing a bit of hardened steel. Cut a little short of where you want the edge to be and you won't have to worry about blueing the blade. That will be quick to grind past.
I have a couple similar irons stashed, I can't bring myself to throw them away, still dodn't know what to do with them.
An old blade of mine that was unusable in a plane was cut and made into a couple of marking knives:

The knife in the center was made from a broken saw blade. The ferrule is a sleeve from a brass compression fitting for 1/4" tubing.
Here is the story on my second marking knife made from a plane blade:

It is my most used marking knife.
