I don't have any stripped knives but on the carbon steels that I have that came with no coating, I used a wax mixture that I rub on: Equal parts linseed oil, beeswax and turpentine.

I melt the beeswax and stir in the turpentine then the linseed oil. My grandfather used something like that and for a hard-use knife, it wears well. Not a lot much oiling required afterward.
