Found an old knife that needs cleaning, and preserving

[Old River]

Does anyone know what to do with a knife like this. I'm afraid I'm going to lose it if I don't do something. Would it be safe to use electrolysis, and what can I put on it to perserve it. I would appreciate any help I can get.

I'd let it soak in PB Blaster or WD-40 for a while. Take out now and then and wire brush it. When you like how it looks, clean it in Dawn dish soap, rinse in real hot water, dry , and then spray with clear Rustoleum.

Good luck! HH

Thanks. I'll give it a try.
