I have a regular King 800, and I use it an awful lot, especially for polishing finishes.
my current sharpening setup is my favorite yet: Shapton Pro 320->1000 Chosera->Gesshin 8000.
spoiled myself early on (after a year with a togiharu 1k/4k combo), with gesshin 400, 2k, 4k. have to say, i find myself really enjoying sharpening with these guys. i keep 'em in the pond all the time.
just found a shapton pro 1500 at work, been digging that too actually
DMT xxc and course
1k, 3k and 5k Superstones
Sharpton 8k and 16k
felt and 1micron diamond
I recently switched to a splash and go set up. The line up seems to suit my sharpening style well. I'm a little slow, soft and deliberate. The Superstones are butter smooth, and I'm not much of a gauger, so I haven't had any problems.
The difference between try and triumph is a little "umph"! NO EXCUSES!!!!!!!
I have a King 800 but never use it and was gonna buy something in the 700-800 range to replace it and go with a 2 stone setup with my Rika, but I might give the King another go
I just ordered and received both of these , Combination (Two Sided) 1000x/6000x Water Stone & the King Deluxe 1200 , and the guide also I have a few other water stones from when I was stationed in Okinawa . I will soon have to replace .
