My wife is fond of a little Crisco on our kitchen blades when they are brand new. Once the patina develops, it is a partial protection from rust and we only wash and dry after using, then put them away. No need to keep oiling, in my experience, once it looks like old pewter.
There are different recipes for creating a patina. The old Morseth knives suggested the owner spend a while slicing tomatoes, citrus, and meat to get a patina going. This is after cleaning off any oil.
I’ve seen the suggestion of dabbing mustard all over the blade, too. How you apply the mustard will determine the pattern of the patina.
My own method is just to put the knife to work preparing food. After a week or so it will have a nice grey color that only improves with time.
That’s a really good looking knife, by the way.
