Thread: Any experience with Suehiro Gokumyo Hones?

Not that you need to but I put 40 half strokes and 30 x strokes on a test blade and no microchips! You never need to do that many strokes at that level I know but I just wanted to see but there were none. So I would say its not prone to micro chips at least in my test. Shaves are great. I have the HAD and ordered the 15 k. Should get it next week. And 3 more stone holders!

You'll have to tell us how you like the 15k!! I have thought about getting one as well but have not pulled the trigger yet....

Like you and many more of us have settled on the Gokomyo series as our principal hones. I have the 15 k and the 20k.

I have found an issue with truing (flattening). The DMT 325 is fairly harsh. Leaves scratches. Should I look at a higher grit lapping stone like the the atoma's At present I'm using 1200 wet/gry...someone help me, with this, surely not the shapton lapper

Stu from Tools of Japan warned me off wet/dry for the SG. My experience with the DMT 325 did not leave scratch marks on my 20K.

Mate, whats the story about truing this 20k stone? Do we need a $350 dollar lapping plate to lap this stone. I'd rather a 1200 atoma plate? Any ideas men

I use a DMT 325 on my 20k, and have no issues. I'm sure an atoma 1200 would work, might take a while though. I'm thinking about getting a higher grit diamond plate so I can quickly flatten with the 325 then polish it to a smoother surface with a 1200.

Here's the thing fellas. New diamond plates that aren't very well worn will leave nasty anomalous scratches. Look at your flattened stone so that the reflection of a light source is visible at a high incident angle and you'll see them pop out like a sore thumb. My preference for this stone is lapping with a well-worn Atoma 400. An Atoma 1200 will work too but really slows down the stone. Even well worn plates leave some scratches, BTW, but not as deep or anomalous.

The Suehiro will likely strip the Atoma.
After I go over it with a well used 325, I then proceed to smooth the surface with a Coticule. Works well for me.

Mine was very hard and had a dip in the middle that left rough deep stria on the bevel. I lapped it with a 140 CKTG and a 300 I Wood plates.

I have been using the slurry/cleaning stones it came with, 1 & 3K and like the polish on the bevel, it also smoothed out the feel, felt gritty before.

Will have to try a coticule on it.

Bill, like you I have HAD. I bought the 20k Suehiro from tools from japan, and wanted then to buy it's little brother, so I ordered the 15k (Against the advice of Stu from TFJ, who said it was superfluous, after owning the 20k) But HAD is a powerful thing, and I am thrilled with the feather like pressure on these 'difficult to use stones' that give what is nearly an alfoil edge, absolutely marvelous, mate, what do you use to flatten the stones? Bearing in mind, the only real need for flattening is when the stone is brand new. I Grid it and use the dmt 325) But am unhappy with the scratch marks left by the rough dmt, (It is fairly new). Your thoughts?
