Speaking of, I just had to do this very thing with a restored W&B FBU. There was a nasty “hole” in the edge from pitting that I nicked myself on a few times. Enough was enough so I DMT’d it out this morning, still has a healthy 15/16 left.You are going to have some issues with the remnants of rust. There are some deep pitting (holes) in the blade - some closer to the edge.
It is not such a big deal though, when you encounter them you will have to hone for a bit to get past them. They create "U" shaped irregularities in the edge.
Very nice save!
What about the pits around the tang hole? Do you think they should somehow be cleaned out before pinning, or are the pits dormant enough to prevent further red rust from forming?
