Hunting Knife Restoration Tips Sought

[S.Workman]

OK, here are some pics. I would love to get them cleaned up to carry. I live in a state where you can carry anything you want anywhere, although I usually carry smaller things. I do hunt though, so they may be tasked for that. You can see the marks, the spacers, and the strangely abused pommels.
You can see that the tang is peened within the brass slot, so to replace the spacers I think I would have to grind off the peened over end and thereby shorten the whole thing by some amount. On the hollow ground knife the spacers look to be horn, but they are plastic on the other one, bakelite or something.
