Hi guys!

I have thought about getting into honing but what do i need for this?
The Norton 4k/8k seemes to be what most people use, but do I need anything else?
I was told by a seller on the perfect edge I need a flattening stone with it..do I need this?
Also, do I need a finer stone to use after the norton 8k?
And what is "setting the bevel"? I've heard it alot but never understod what it means.

Thank you!
