Sharpening stones, oil, water, diamond


I’ve been wondering what kinds of oils were used for oilstones prior to petroleum distillates. It seems like most light oils are also drying types, which would be a problem.
Waterstones are nice, but can’t be allowed to freeze. And diamond stones aren’t reproducible in a non-industrial situation.

Good question. I bet Japanese woodworkers would know.
