I found it very confusing to read about, but once you dive in and start doing it yourself you'll be going "oh, THATS what they were talking about"
It's definitely not rocket science but there is a learning curve.
It's like any other skill, you've just got to get stuck in. If you wanna learn guitar, get a guitar and start playing.
If you want to hone, get some stones and a razor and get going...! :)
Amazon sells the 220/1k and 4/8 norton stones, plus a lapping plate for about $120. Thatll set you up for anything you need to do. You could add a finishing stone or paste if you want to, but that'll literally do you for anything as is.
