I saw in a video someone used Camellia oil to clean up hand planes after each use before putting them away, to keep them looking like new over many years of use. I'm curious to see what others use and if you recommend Camellia oil, what type? I see cold pressed, and I do see some for blades, but they seem to be much more expensive. Is this due to a different processing? or just hype? Please share how you maintain your hand planes! and thanks!
