DON'T "Clean it up" or "Restore" to make it look new!
That destroys all the history, and if a "collectable" destroys any value it may have in its original used condition.
"
Preserve" what is there. Get rid of any active red rust. Sharpen the blade(s), clean the joints as and how mentioned above, then lube the joints with mineral oil. A patina helps prevent rust by the way, and does not harm the blade(s). No reason to get rid of it.
The bolsters don't have to reflect like a mirror, either. (Actually, highly polished bolsters and blade(s) on an old knife are signs a blade or blades have been replaced, and the knife may be a fake, or "Frankenknife", made up of parts from several different knives.
As others have stated, pictures will help.
You'll need to use a photo hosting site like Imgur, (don't use Photo Bucket) or upgrade your membership level to at least "Basic" to post photos.
(instructions on how to post using Imgur et-al, are in a stickie on the top of the first page of every sub-forum.)
Welcome to the forums.
EDIT:
If that is your SAK type knife in post number 8, just sharpen it, oil the joints, and use it.
Those blades don't look bad, nor like they were ever mirror polished.
