Looking for something for my synth polishing progression. 3k side of my cerax combo is almost completely gone. I like it a lot but I am curious if I should get a Morihei instead. What do I do?

If I buy the morihei only to find out it’s basically as good as the cerax (cost twice as much) and no one warned me I’ll be pissed

I would say that the edge left behind by the morihei is noticeably finer than the cerax 3000. But not by much. The morihei is a slightly harder stone than the cerax 3000, so it will last a little longer. I do enjoy tactile feel of the morihei better than the cerax. I myself wouldn’t pay the asking price of a morihei. It’s a little much for a 4000 grit stone. But if money was not an issue, the morihei 4000 is very much worth trying.

Thanks but I picked one up, been using it interchangeably with SG4k. Both excellent edge finishers in different ways. Much prefer the Morihei 4K over chosera 3k
 
I like never post in here, but couldn’t not post to this. Personally, I have both stones. I love both stones. But I love the morihei more. The Cerax 3k feels absolutely amazing to sharpen on, but I personally feel that the edges off the morihei 4K are far better. I feel as though the morihei will also last longer than the Cerax. Plus the morihei doesn’t load up the way the Cerax does. I feel like I gotta lap the Cerax every 2.5 seconds, whereas I don’t need to lap the 4K anywhere near as often. If I could only choose 1 between the 2, I’d go the morihei every time

Could you elaborate a bit on what it is you prefer about the Morihei over the chosera? I love my chosera 3k and also really liked the Morihei 6k. Just found it a bit fine for the edges I usually like.

Just personal preference for me. Morihei 4K just suits my manner of sharpening better, chosera 3k feels quite “buttery” where as Morihei 4K is more JNatty. Finishing edge was more refined but still 4K.
 
Do you guys use the Morihei for polishing, or only sharpening? And when sharpening, does it take too long to raise a burr on simple carbon steels (a tiny burr of course)? Or you just use it for stropping / deburring?

My only 4k is the Gesshin soaker. Love how fast and efficient it is for sharpening; not in love with the polish or with how it feels (not as creamy as other Gesshin soakers). I’m sure the Morihei is not as fast but if it can polish and sharpen well and feel good doing so, I might grab one.

I use mine for both.

It’s reasonably fast if you raise a bit of slurry and feels nice to sharpen on. Haven’t used any other 4k stones so can’t compare though.
 
Morihei 4K creates nice polish on core steel along w really nice edge. I can’t get good results on the blade road with it but that might have more to do with my skill level at the moment instead of what the stone is capable of doing. I’m uncertain
 
I permasoaked mine. It’s been that way for awhile and there’s been no damage so hopefully it’s okay to do so!
It does seem to saturate rather quickly so I’m not sure the results are improved in this particular instance

@Ok__mode_6953 @labor of love thanks, sounds good. Do you use it as a splash n go, or give it a quick soak? I know it's supposed to be SnG but some of those still benefit from a quick soak or running tap water over it...

I run mine under the tap for a minute or two whilst i'm cleaning up a bit out of habit, but it's good as a splash and go!
 
Morihei 4000 is quite possibly the best 4000 grit stone out there. Gesshin 4000 is great too, but I like morihei better. The edge is the truest 4000 grit edge, and the stone itself is very high quality.

May I ask why you like the Morihei better than the Gesshin? I have the Gesshin 4k and really like it, but I’m not a fan of how it feels. Also it cloggs a bit.
 
shobudonnie said:
Because of what you just said. It clogs and the tactile feel isn’t the best. Morihei 4000 is just overall a much more complete feeling and perfected stone.

got it... do you feel the Morihei is much slower than the Gesshin? I'm guessing nothing in the 4k range is as fast as the Gesshin, but does it feel like a big difference in speed? (by speed I'm thinking mostly burr formation)

The gesshin 4k is somewhat faster, but I think that cutting speed doesn’t matter too much for 3000 grit and above. These are finishers. You shouldn’t have to do anything more than two passes per side on these stones.

I think cutting speed really matters for 2000 grit and below. When you are trying to set a brand new edge and getting that initial burr going.
 
Gesh 4K is pretty awesome but IMO once you start considering $140 synths you might as well start buying jnats. Unless you really really don’t want the fuss and rather keep it simple. Or if you’re sharpening lots of stainless knives.
SG4k gets it done quick enough for less than half the price.
Mori 4K is slower than both but IMO is faster than chosera 3k and I dunno the finishing edge just feels really good and is quite enjoyable in use so I don’t mind the extra 20-30 secs or whatever. $80 synth finisher that mimics a jnat in feel somewhat, worth keeping around until you find the perfect jnat for you or if you hardly find yourself using a 4K stone as a touch up stone.
 
What I enjoy about the Gesshin 4k is that if my knife is not too dull and the steel abrades easily it can be a one stone solution - sharpen (raise a small burr / refresh the bevel) and finish (just deburr and you have a great edge).

For me it substitutes a 1-2k + 4-6k combo in many situations. Sure it takes longer to raise a burr than a 1-2k and isn’t practical for every steel. But I like having to deal with only one stone.

But yeah, the price is high, it’s not a great polisher, and feels kinda rough. If the Morihei can still raise a burr somewhat easily, and also polish better and have a more enjoyable feeling, I’m sold. It seems the Morihei cuts faster if you raise some slurry so I’ll try that.

I just ordered one, we’ll see.
