Another vote for mineral oil. It's inexpensive, works well, and food safe. I don't force a patina on my carbon blade knives- just use them and keep them clean and oil every week or two or as your lifestyle dictates. I've got knives in Case's CV steel and Opinel's carbon steel and haven't had an issue with rust on either. Patina might be a little slower to develop naturally, but I think slicing a couple apples or potatoes will patina the blade enough to start protecting it.
