If you are worried about hitting the ivory, don't -- you can sand up to 2000 and then use some maas on a felt pad on your dremel @ low speed and re-buff the ivory back to mirror.

Whatever you do, don't sand the word printing on the ivory ;D it will go byebye.

For the little dimple between the blade and tang there, wrap a pencil in sandpaper and sand that down...

go to 2000 grit after all rust is gone and then do the same motions with a rag /w MAAS on it (wrapped around finger, wrapped around pencil)....

thats what I'd do!
Be careful and patient and this will work!
