Hello SHARPCO! I've tried experimenting with this as well and without total success. I've used both olive oil and vegetable oil. I wonder now if the problem is that these are water based (soluble) oils and contain some water themselves. I know that there are some mineral oils (hydrocarbon based) out there that are safe for human consumption. In a former life I used to sell 55 gallon drums of the stuff to health food stores. Perhaps that is the answer. I would assume though that someone out there makes an oil that is safe and recommended for protecting the surface of steel knives.
