In this regard, how do you maintain a wood plane?
Subsequently, how do you restore an old block plane?
How do you restore a rusty hand plane?
How do you clean a lie Nielsen plane?
What kind of oil do hand planes use?
Pretty much any thin non-drying oil will work, as will wax. A mix of beeswax and mineral oil will work well for seldom used tools (i.e. long storage), but is a bit thick for daily maintenance. (requires a wipe on, wipe off, technique). I use it for my specialty planes and hand saws.
