Nice old knife. I would just oil the joints and take a number 2 pencil lead to it if you see any active rust on the metal. That's all you need to do in my humble opinion.

[bronco2]

ok, thank you sir

[Ridgegrass]

Absolutely agree. No abrasives. J.O'.

Ditto.
When my blades have that kind of patina, I wipe them with oil occasionally, as well as oiling the joints. It keeps them from rushing and gives a beautiful shine that I appreciate.
You have a beautiful knife there!
