The JNats you don't know what to do with

Is this Koma nagura good to buy? I want to use it with my Ozuku Asagi.
The vendor says: “ Mikawa Shiro Nagura Koma from Aichi, tested quality, supplied directly from the producer”

Pretty rock! I'm so scared of the jnat hole. I've got a mountain of arks, but I've used them my whole life. I think I got as many coticules as arks and random things like a lyn idwal or la lunes from mystery hone fun but jnats go for a premium and sound as hit or miss as coticules if not worse! I bought a mystery stone and I think it might be a jnat but I've got no clue, part of the fun is trying it without any influence, just purely your opinion of the the stone... it's good stuff.

Usually if the stone sucks I'll search out the people of the forum but I only ask about identification after the purchase. It makes it like a scratch off but without the gambling because the stone will be useful for something at least! Lots of research about these stones ahead of time and buying from trusted sources(so I hear) helps with jnats. Here is the mystery stone I just bought I bet it's going to be fun! The chipping looks like chert(arkansas stones, flint) but I don't know, never seen an ark like that. The saw marks and little bubbles on the stone kinda reminded me of a jnat, but I know nothing about them!20210905_130140_resized.jpgScreenshot_20210905-125810_eBay~2.jpg20210905_130140.jpgScreenshot_20210905-125810_eBay.jpgScreenshot_20210905-125806_eBay.jpgScreenshot_20210905-125758_eBay.jpgScreenshot_20210905-125801_eBay.jpg

Ask me about shaving naked!
Very grateful to you all! With trepidation here’s some pics- I know it looks awfully worn but in my defence my Aust looks nothing like this and I’ve honed that too. I use Lynn Abrams circle technique and Slash’s pasted balsa. I’ve tried rolling x ‘s and burr method too with the TI. When I use the sharpie, I’m clearing all the ink in a few strokes.View attachment 1322710View attachment 1322711View attachment 1322712View attachment 1322713View attachment 1322714View attachment 1322715View attachment 1322716

Looks decent, it should be priced at 50 cents/g US or less to be a good buy.

I have a lot of koma. Most of the Asano stamped stones (as this one is) are hard, and you’ll need a hard hone to use them. Alex Gilmore had a softer modern one given to him by Sakimoto San (Asano) during their visit in Japan.

All of the koma that I have is very fast, grit rich, whether vintage or modern, hard or soft. Modern tends to be harder and finer, vintage tends to be softer and coarser.

A good option is mejiro, Sakimoto San says that it’s finer than koma, but slower and not as rare. A good piece of mejiro will certainly get you to the same place.

Hi Steve,
Thanks for reply. I ordered it already from a german eshop. Cost 85€ + shipping, bit pricey, but what can i do if i want to jave fun. Want to play with it and learn more and more about honing on JNAT”s.
I will use it with my Ozuku Asagi LV5+, i alredy have Asano naguras botan and mejiro, want to play with this Koma and will serch for Tomo nagura to comlete this setup. Maybe it will be fine only to make slurry with Atoma 400 or 1200

That’s the problem with most Japanese mid grit stones, they just aren’t very fast. It’s difficult to justify honing 2-3x longer than using a synth when you end up on a JNat finisher anyway.

The JNat stones that i use as ‘tweeners’ - between bevel set and finish - tend to be super fast tomae layer or a deeper layer, or a suita. Some of these tweeners can also finish very well too. Once you use one of these, it’s just darned hard to pick up an aoto or tsushima.

I used to feel that Mikawa weren’t really worth using either, just too slow, though they are a lot of fun to use. Over the years, I’ve acquired a small number of them that are so rich in grit that they can be used in place of mid grit stones. Many of these were bought in lots with other stones and are unmarked. None of them have Asano stamps.
Fascinating

I am missing a koma, but i have a hard mejiro. Kan i mix a tomo slurry with mejiro and skip buying a koma? I was thinking that if i first create a little mejiro slurry, by rubbing a hard tomo it would breake it down a little.
