I never have considered that there wouldn't be some friction, Isaac,
occurring as a natural result of the two surfaces  (jack tip and knuckle)
interacting with one another as they are designed to do.  However, to
introduce friction by the addition of substances to the knuckles would be
unnatural to me.
