Last week I had the double sided stone. I got the double sided just so I could try both stones out.
When I first got the stone I went and checked out the price to see what category it would fall in to. http://korin.com/Mizuyama-1000-6000-...ategory=280108
1k. I soaked the 1k for about 30 min which is about how long it took for the crappy work knives to get up to this stone. The stone was a faster cutter than what I am used to (king) and def. a lot less mud than the king too.
I have used the sigma II 1.2k stone also and that one was more muddy than the Miz.. But the Sigma was a little faster cutting which seems like the trade off. Because of the lack of mud I seemed to be cleaning off the swarf quite a bit.
All in all I did do about 10 knives that day. From crappy work knives to carbon (Shigfusa, Mizuno) to my Globals. I had no problems at all. The stone was a good work horse.
6K. When I soaked the stone I made sure that this part of the stone stayed dry. In fact I only soaked the 1k side to about half way up. The feel of the stone is very soft. Softer than what I am used to in fact I ended up putting a couple gouges that I couldn't get out. I liked the edge it left on all blades. Quite a bit of mud and also would fill up very slow. It wouldn't cut as fast as the 30k but was not bad at all. I found I liked it better than the 1 by a lot. I can see picking this up in a week or two.
Not being much of a whet stone guy I hope I did the review justice.
