Thread: J-Nat club

My latest acquisition.
A perfectly usable to hone on, Botan nagura, very fast after 4k synthetic and leaves very nice edge. I think it is a stone that bridges synthetic to prepolisher gap in a natural progression.

Heck thats just a cool looking stone

My latest purchase is in the post from Alex


According to Alex

This is a Vintage Specimen Karasu KAMISORI TOISHI.

This large raw shaped stone is rich kuro (black) on asagi (grey) that is called karusu, an allusion to flying black crows that has grit so fine that it feels like it would not affect steel in any way, but as it turns out it polishes the steel with an amazing ability.

With a light slurry the cutting action is noticeably fast, but with no slurry this is a true polishing stone with a hardness level at Lv5.5

The solid tan lines are typical of some Nayamaya stones and are structurally solid
and do not affect the honing action in any way because the minerals are softer than
the sharpening medium.

I have wanted a Karasu for a while now so i can not wait to get it!!!!! Thanks Alex!

This is not helping my HAD... AT ALL...

Yes a Karasu is on my list of NEEDS... Someday I'll bump into the right stone

It is addictive, the jnats are just nice to look at and use. This should make my 20th jnat when it arrives

Killer looking stone Brighty!

Luckily my Lv5+ Ozuku gives me killer edges, so I have avided J-Nat HAD... Or else I'd be really broke fast!

This is my J-Nat, it's a Nakayama Kiita. I got it a few months ago from Alex. It's almost a perfect rectangular and is roughly 6"x2.75"x1". The line you see in the surface does not affect honing at all. I find it works best if I work up a slurry with the small tomonagura (far right in the picture) that I also got from Alex, honing on the slurry while gradually adding drops of water as I go, simply going by feel and not counting laps. I finish on a really light slurry, strop, then rinse the stone off and do some more laps on a thin film of pure water, the strop again. The edge is then uber-sharp.

I have a set of nagura as well, as you can see from the photo. Left to right: Botan, Tenjyou, Mejiro, Koma, and the small piece of finishing stone I use for the final slurry. The second picture is a scan of the surface of the stone. It's a Kiita, but I see distinct blue swirls and patterns! Very pretty.

I have a Ozuku Asagi Lvl 5 in the mail right now. I'm so excited to give it a go!!

My latest arrivals

#1 - Nakayama from Alex - This is quite a hard stone, level 5 +\- and very smooth (its a very nice stone to use)

#2 - Ozaki iro from Alex - I have another stone almost the same as this stone, but this new stone is slightly finer. About a level 4 in hardness

#3 - A Nakayama kiita from Alex - This is a smaller stone and it brings a slurry quite easily and when wet it becomes a bright yellow. This stone is probably a level 4 +\-, fast cutting and has a really nice earthy smell to it.

Brighty. I think you now qualify to have HAD appended to your username but you'd have to get it past Jimmy first
