This is the stone that I use as my base for creating a kasumi (mist) finish. This stone gets used on nearly 100% of all wide bevel Japanese clad knives that I sharpen professionally.
This stone produces a matte finish. For rustic kurouchi finished knives this is often the finish level I leave,. For yanagis and other refined finished knives I will follow this stone with either natural stones and/or finger stones.
There is no one answer as to what stones should be used to create that kasumi finish for every knife but you can count on the King 800x to give you a smooth contrasting appearance every time.
