I recently got an old French frameback (not one of the swiss Lecoultre ones) with a replaceable blade. The blade it comes with, unfortunately, has been honed to a pretty bad frown.

Now I'm wondering, how hard would it be to get a piece of good steel of the right thickness and get it watercut to replace the blade? Seems like it shouldn't be a big deal at all.

Of course the bigger deal might actually be getting the honed-out blade removed, as it's pretty well rusted in...

It looks to me like this frameback would probably take Lecoultre blades if I could get some, but again, that'll require de-rusting it enough to get the blade it's got out.

It's definitely removable, as it has a set-screw on the toe. It's in otherwise excellent condition.
