Unscientific rust prevention test with common household oil

[Johnbeck180]

I use Hoppe's gun lubricating oil, works great just a small amount goes along way. I spray a little on my finger and rub it on my blade, seems to thicken up after rubbed in.

I insist on a food-safe protectant; I see no reason to restrict a knife from being used on food. (in fact when we designed this example, the client specifically stated she wanted an EDC that she could whittle with, open mail and whatnot, and slice sausage and cheese for her lunch - which I think is almost the perfect definition of an EDC.)

Anyhow, looks like I'll be ordering some Fluid Film to try. I'm certainly open to other suggestions.

food grade silicone spray? 16oz can (10oz product inside) under $10.
