Thanks for the offer - I just scored a 6/8 or 7/8 wedge on e-bay that I'm hoping to restore.
Hopefully you still have a wedge when the regrinder's done!

It will still be a wedge, just with a bit more metal removed in order to:
1) Even out the spine and the front side tang around the pivot hole (I removed a lot of metal in cleaning out the pitting from those areas)
2) Remove the micro-pitting from the faces.
The blade will probably keep its wedge shape, just be reduced to a 4/8.
