If I am to understand the
ballize description provided by Dan, the hardened ball bearing is
pushed through the hole, essentially smashing the bumps and
scratched flat. Now I have a reason to hunt for ball bearings on
ebay.

Exactly right. Kind of a poor man's burnishing tool. Here's a guy on
Ebay that sells gage balls (cheap):

Nice find! But where are his metric-sized gage balls?


Don't know, but he must have bought a dump truck full of "inch" sized ones
at an auction or something. He's been selling them on ebay for some time
now.
