Depends on how dry the wood is after you have oiled it. I would use PVA wood glue if the wood is dry enough. Apply glue and then clamp the crack together and allow time for glue to dry.
What is your plan regarding the rust on the staples? If you are able to remove them from the scabbard easily then maybe they should be soaked in vinegar also. I have never owned one of these knives so don't know how the staples are fitted. If they can not be removed easily then maybe rub some vinegar on them with a rag.
A word of caution....If you do remove the staples make sure you number them so they go back in the same place. They look to vary in length.
