I have a few oldies that are kinda beat up. In particular, 3-4 camper/boyscout type 4-blade knives. The blades are kinda gummed up, as well as the internals. They are very old.

What is the best way to get them spiffed up a bit? I was thinking of actually soaking them in something (actually submerging them). Or just spraying them with a lot of Kroil and letting them sit.

Or I could just hit them with brake cleaner or lighter fluid and then some Kroil. 1-2 may have plastic scales though, so not sure.

Also wondering about touching up the blades a bit. Just to remove surface rust, not necessarily patina.

Ideas?

Thanks..........
