Thread: nakayama maruka vs Uchigumori?

Guys,

found a stone on ebay. This is the description:

''
You are looking at a beautiful Japanese Uchigurmori sharpening stone. This is a very special ultimate class stone which I will guarantee satisfaction with a refund or trade, please read the return instructions for details. These stones would be worth $100's more if they were perfect so please look at the pictures for condition. These are the best quality available. Thank you for looking.
This large size 180X67X27mm 835g stone is Uchigumori from the Nakayama mine in Yamashiro Umegahata Region of Kyoto. It is a hard very fine grain and very abrasive grit with a good light positive feedback, which polishes to a very high degree. The lines or cracks have no affect on the sharpening and polishing of this stone, it is a top grade stone. Please note the picture with an iron flower, which are the particles formed while sharpening. The slurry is formed from a 30 second grind.
HGAL \5+3+++3+++3++.
H is the hardness of the stone on a scale of 5
G is the grain, how fine the grain on a scale of 3
A is the abrasive power of the stone on a scale of 3
L is the lightness, the feel of the stones feedback on a scale of 3
This stone is so abrasive and so smooth. I have been asked what grit these stones are, and that is a very hard question to answer. The beauty of the Tennen Toishi is that it may cut like an 8000 grit stone but the longer you use it and the slurry builds, the grit size breaks down and it may be smaller particles than a 30,000 grit Shapton. With a very high grade stone like this one, you end up with a beautiful mist and haze that no artifical stone can match.''


What do you think guys? I am no expert, but the info makes me think it is a good stone for polishing my plane
blades.


The stone is 150 something dollars. There are a couple
on ebay for others who might be interested.

That guy has stones with those stats listed for $155 pretty much all the time. I'm sure you'll find someone who has bought from him.

I did a search and found the hones you are referring to (they all look like they have cracks in them, but that could just be the way they are - I don't know).

I dunno if this means anything, but those ratings are the same as 330mate's system. So I checked that guy's feedback and, sure enough, tons of purchases from 330mate. Makes me a little suspicious...

Hi again,

I did not want to post the link as I have just joined
the forum and it may look suspicious.

Very sharp holli4pirating! I checked it as well and you
are correct. A lot of purchases from 330 mate. I think
all stones were like 50-60 dollars or so, which he is now selling for 150 dollars or so.

Don't think it is suspicious. Just buying stones and selling for higher prices.

I am guessing he bought a lot of stones and got discount
from 330mate. So the question is can I buy the stone cheaper from 330mate?

If I remember correctly I sent a message to 330mate
and telling about what I wanted and he just recommended Shapton stones

With this info I am going to mail him again.

330mate is sick of razor honers bugging him I think. He started listing a "for razors" size (only $22 shipped, worth a gamble really) a couple weeks ago, and a few members have posted emails from him where he complains about how we ask him to handpick stones for us without paying him for his time.

Personally I'd probably take the gamble on one of his $22 size nakayama's and figure it money gone (a movie, popcorn and a drink these days)... then if that didn't work out I'd either take his advice about the shapton or bite the bullet and pay $300+ for one from someone who caters to razor honers.

Veins in a stone are not a problem if they are soft. Cracks on the other hand can be.
I am just suspicious of someone advertising Uchigumori as a razor stone but he has good feedback from sales. Your choice.

Thanks for the info.

I was thinking if the lines are very narrow then there should be no problem, but wider lines might cause the
blade to go in these lines.

Lol. I have the feeling you might be right about him being fed up of looking for ''special'' stones for people.

The 22 dollar stones are too small for me(sharpening plane blades). I emailed him and explained again what I need and that I was willing to pay more for the ''special custom'' stone.
