Morihei 4000

I 100% agree that this stone is one of the best for high carbon steel. More than a polish for my ZDP189 knives. I can't say which I like more: Morihei or Naniwa Pro. If you want a glimpse of JNAT, then by all means use Morihei. Did not thought it will work so fast on high carbon steel. Highly recommend it.

This is an exceptional stone - love at first feel! Being a true splash and go with excellent feedback, smooth and soft, Morihei's Fire 4000 is a stone that makes you find excuses for using it more often. It gives you a superb finish which is even more satisfying as it is not flashy at all. Of course, it works very well as a stepping stone to the higher realms of honing, but, frankly, for most kitchen knife uses this is all the finish you need. - This stone loves its traditional and honest steels, such as white and blue paper, and I'm not sure if I would want to use it on HSS as I believe it would be relatively slow. However, speed and efficiency are not exactly what you're looking for when using a stone like this. - Use with Nagura. I have some natural ones at home which make, as I believe, the stone shine, but - side note to Sami - I would very much like to try out the Nagura Morihei has intended for it. All in all a sensational achievement. Kudos to Morihei!

Lovely s&g stone. It just feels different. And great. I guess it's not the fastest one out there but fast enough. It's hard enough to not be cut by the knife if you're technique is not up there yet. The resulting edge is perfect for kitchen knives. Crispy sharp with enough bite.
