Well, could you say some words about your way that works for you?

No. I mean stones like Nakayama Maruka HATAHOSHI Tomae Kiita from reputed seller.
So it's rather about quality in general, not about specific properties.



When you are buying stones from...

It's not that hard. You can compare Koma to other nagura stones that you already have.
It should be noticeably finer and leave no outlier scratches.
As for me when I got my Koma I asked one very...

You don't need any bad stones.
A bad beginning makes a bad ending.

With bad stones you get negative experience.
With thousands of bad stones you get a lot of negative experience.
Do you...

Once you have good razor finisher like Nakayama Maruichi Asagi or even better Oozuku Karasu you don't need any tomo nagura.
Such a stones with good honing technique give HHT passing just before...

Thank you for quick reply.

My question has been about tomo nagura ( 共名倉 )。
And I think I'd prefer to buy one good koma than test some hundreds of stones to find which one is better to use it as...

So you think that when one could hone with BOTAN nagura on the most finest stone the result would be the same as with KOMA on the same stone?

DMT diamond plate istead of natural nagura is a kind of palliative. It works well in some cases, for example for...

You don't need to be so sceptic. Just try it and check the flatness. All you need for the experiment are a piece of flat glass ( thicker is better ),
some flat surface to put it on and loose...

Use sliding and rotating 8-like motions on slurry and you will have no such problem.

BTW when you are lapping jnats on hard ceramic or cast iron plate you wouldn't have troubles with wearing of...

I don't like how DMT is lapping hard and fine grit stones.
I'd prefer to lap with set of silicon carbide (SiC) powders up to 1200 grit with just sheet of glass on some flat surface. Or with...

And one more thing to add: Sometimes working surface of stones needs to be lapped before use for razor honing to get the better result.
And it is also good to round off the edges of the stone...

I can not decide on stone quality by photo.

You should try to use it.

My green Oohiras looking like your's are not very suitable for razor honing.
So I'd prefer to use hard Nakayama Maruka...
