Its really nice to hone on, very fast cutter but i only use this on knives... I actually really would like to get a japanese sword oneday although a genuine one is soo damn expensive

Hi folks,

Here are some pictures from my Nakayama Maruka (13,5 x 8 x 2,5 cm):









It is a rather soft and "thirsty" stone, i.e. water is getting absorbed pretty quickly. A slurry is easily raised and boy, is this stone fast !! The slurry darkens after a just a few strokes and a razor dulled on a glass is being honed back to shaving sharp extremely quickly. The stone does not leave a mirror but rather a hazy finish.

The shaves of razors coming off this hone are very comfortable .

Cheers
Jörg

Hi Jörg,

Nice looking stone, The "hazy" finish is is common on jnats expecially the softer stones as it's caused by the slurry itself. I have a few stones that soak the water up just as wuick and althogh the softer stones are generly more knife friendly its good this one is giving you the comfortable edge you need!

Just in case you didnt know, im 'failry' sure Maruka means the stone was mined at a time when Nakayama owned by the family of Kato
before it was replaced by Hatahoshi, and Hatanaka - So its a true Nakayama

Thanks for sharing it!

Here's another J-Nat, a Nakayama Iromono together with some naguras:





This one is harder than the Maruka but not quite as hard as my small Oozuku. A very easy stone to use .

Thats a really nice looking stone and bunch of Naguras! I like the look of the more natural un even look compared to the square look that usually donst have the skin.

Looks like you have a nice collection! Throw up your Oozuku aswell!

Thanks again ! I also like the "rough" look - btw. the stone you have shown a bit earlier is a wonderful specimen!

Here's a snapshot of the Ooszuke (unfortunately I don't have any better pictures at hand right now):

May I ask how you use the slurry, is it a thick slurry on a cloth or something? Have you experimented with slurries of "lower" grit
stones when removing scratches?

Thanks!

medium slurry works usually.
If you go thicker consistency you just need to hone with it longer to make sure complete breakdown of the particles.

Fikira, If you want to experiment with powdered jnats for polishing, check out "nugui" powders.
They are mainly for swords but fun to polish anything with.
It's made up from jnat powders, iron oxides, chromium oxide, camellia oil, burnt bone (human teeth in one recipe) and whatever you feel like putting in as your secret ingredient.

That looks very interesting! I'm using sanding paper and micromesh, and of course it's much work to remove the previous scratches!
Now, because you'll get a nice hazy finish when honing on Jnat I wondered if you could get such a result when we're restoring!

Is it possible to remove deep scratches with the powders or slurries? Does it saves time? Are the "wa" powders similar?
And are there series of progressions in powders?

Thanks!
