Just got this Green Brick.
Naniwa Aotoshi 2000 Grit
Golly. The logo on the box has a
shrimp on it but the hone is no
shrimp. It very much cleans up
an edge after setting a bevel with
a Norton 1K and eases the move
to finer hones much more than I
would have expected.
It is soft so keep a lapping solution
handy.
It also does a grand job on kitchen knives.
so is this the so called "green shrimp" i've been hearing about?
Nice stone! :tu
I think the green shrimp might refer to the Chosera 1k? Thats a pretty popular stone right about now!
those are very popular for knives, very soft stones.
I'm familiar with the Naniwa Choseras and Superstones. I know nothing about the Aotoshi line other than knowing of its existence and now seeing a photo of one. What are the differences/similarities with the other two lines?
The big kanji on the box say 'Green Whetstone Stone', in case anyone was wondering.
:D
The kanji actually says "blue hone," the weird conflagration of green and blue is odd in Japanese, but "ao" actually means blue. It's also "aotoishi" not "aotoshi." This particular stone is naniwa's attempt to make an artificial Aoto, meaning a fast, soft, mid to rough stone for knives.
Never tried it though.
Thanks for sharing. I learned that the first kanji is used for blue / green. Since the stone is described as being green, I assumed that's what they meant. Trust the Japanese to make everything ambiguous :)
It's the most infuriating thing..."ao" means the color we call blue except when it refers to fruit and traffic lights, which are empirically green ("midori," in Japanese) but called "ao". Why? You got me.Quote:

It is a fine hone for both knives and also for resettingQuote:

I used it on a razor from New York
and it cuts "hard American" steel well.
I used it on a German kitchen knife
and it was happy to hone and polish.
I used it on a couple of Shun classic
kitchen knives and the very hard VG-10
gave it no problem.
It is a good 2K hone.
I plan to enjoy it for resetting bevels
on shavers when laps on a 10K
or 12K no longer does the job
(i.e. no need to go up to a 1K).
I also plan to use it after my Norton 1K
hone when setting a new bevel. It very
quickly removes the "roughness" that
the 1K seems to deliver.
With some limited tinkering it might deliver
a better polished edge than half my barber hones.
Highly recommended for those with HAD.
At this point the Aotoshi is not a line it is a point.Quote:

with sand on the stage. It apparently polishes more than the Norton 4K
side of a 4/3k combo perhaps because there is so much abrasive in
the hone.
I have tried my 10K Chosera dry and it seems to like this mode
on occasion. I tried the green brick dry and it seems to clog
with swarf quickly perhaps because it cuts steel so fast.
If you love sharp kitchen knives get one.
If you have a box of shavers (already well honed)
you will not need a coarser hone in the kit. I think
it will let me focus on polishers and finishers.
It is perhaps the most satisfactory HAD induced purchase
I have made.
Does it need soaking?
I think the stone has natural abrasives which break down and thus provide much better polish than the stated grit of the stone.Quote:

Yes but not a lot.Quote:

As the slurry begins to dry it begins to act like 'mud'
with a small splash of water it is cutting again.
It uses white fused alumina, the same as the superstones and chosera. The binder is different, though.Quote:

Similar how? The only description I can find of the Imanishi stone says "It uses a mixture of #1000 and #3000 artificial abrasives to reach an average of #2000" which sounds, to me, like a bad idea.Quote:
