You have to remember many of the folks on this site are in to this stuff as a hobby or have an obsession over differing aspects of it.

People were shaving and maintaining straights when it was the only way to shave and they did it with one simple hone. Really, if you have a Norton 220/1K and a Norton 4K/8k you can do everything from full restorations to touchups and never need anything else.

Once you become taken in by this stuff you become a slave to it and wind up on and endless road to find the ultimate.

Happily I never fell for all of that. Har har.
