I respect your experience but have different advice for a newbies. If I had to do it again I would buy a finisher first and begin learn first how to touch up, then work backwards.
I do agree a Norton 4/8 followed by a Nani 12k is a fantastic setup.
This is a great way to start honing.
Have a blade that has a great bevel set by a pro. Then maintain that bevel with finishers.
Buy a crappy blade to practice with to learn honing skills.
