How do you use the C-3053 burnishing tool?

Actually ... A baseball bat ( and a Hockey stick). are not all that simple to use . Correctly !

That burnishing tool is far simpler.

After trying to remember , I cut the teeth off the original dist. shaft and hammered it in and messed w/ it till it freed up. Then used it to prime the pump later . Lost 2 priming tools and didn`t want to buy another.
