jeweling or scraping not only holds oil better reducing friction, but it also reduces surface area contact reducing surface tension/drag.

Kind of along the lines of the hulls on race boats. Most racers will scuff up the hull where it meets the water, not polish it smooth and wax.

Bearings don't apply to this theory as they roll instead of drag.
