I can't remember whether it was Robert Eggerling or George Werth, both of who make beautiful Damascus, who recommended S.C. Johnson paste wax, it does a good jobprotecting non-stainless Damascus blades and bolsters.
I also use Ren wax on my stainless bladed folders and just need to wipe a bit with flannel cloth or deer skin after they are handled.
Once visited with a collector of high end automatics and linerlocks (up to $15,000.00 per knife and total collection easily worth 1/2 to 1 million dollars). As I handed back each knife he let me handle, he immediately wiped it down with a deer skin that had Ren wax on it then a clean deer skin wipe, then inspected it under bright light to make sure he got all the prints off.
