I'm thinking yes to all of the above. If you got 20+ razors send a few to people to experience different, quality, edges. Get a finshing/touch up hone to easily maintain them, try some chromium oxide, it's dirt cheap, on balsa or leather for even easier touch-ups or to add a little extra polish. Then buy more abrasives and get learning honing from the ground up using the benchmark edges to give you an idea of what you're aiming for.
There's a million options and opinions out there. Personally I find between a 6x2 coticule/bbw with slurry stone, a King 1k/6k & a DMT 325 8x3 I can keep my stones flat, hone from the ground up, touch up razors and keep every metal edged object in the house sharp for many years to come. Hones also seem to hold their value pretty well so you can buy, try & sell, which is nice.
