OK it's not the same kasumi finish you get from using natural stones, I get that, but it's all that's needed to get a clean even appearance on most knives. Take for instance - Takeda, Moritaka, etc. Village blacksmith type knives look great with a simple (and quick) King 800x finish.
I use the King 800x (also) for laying down a base before I move onto natural stones. It greatly speeds up the process to show contrast between hagane and jigane.
This is one of my most used stones and is without question one that I won't ever be without.
