Do not just go to the hardware store and buy linseed oil. It is not food safe cause it is just meant as a wood finish, and has additives to make it dry quickly. You can buy linseed (aka flaxseed) oil that is meant to be eaten, but I've only seen it in small bottles for a lot of money.
Mineral oil can be purchased from a pharmacy for very cheap; it's actually sold as a laxative if you intentionally consume a bunch of it. That is what any wooden spoons or cutting boards you buy would be treated with. Some people mix it with melted beeswax, which gives a nice finish. You can also just buy it premixed and sold as " butcher block conditioner". It's a little pricy, though, and I think it's easiest to just use the mineral oil
Yes, flaxseed oil for salads is great. It just takes forever to polymerize. We're talking weeks, maybe up to a month. But you can still use the cutlery, it will just wear off fast. You can speed it up by boiling it before use, but have to be careful to not burn it or have it go ablaze. I just use it raw and apply it from time to time, eventually it all just blends and I reapply once a year.
