Ah, it was you who got it.
I was in the shed honing razors (lost track of the time) when this ended and I missed out.
Glad to see it went to a good home.
I hate when that happens !Quote:

Yes it was i didnt put in a high bid for it had to go out and when i got home found i had won it nice little surprise im looking forward to testing her out.
We will need a detailed update on how it hones after you receive the stone. Do you hone regularly and know what to look for or are you new to honing a razor? Japanese stones vary a lot more so than coticules which is huge, so we need to know how it preforms to know what you need to ask for. none the less it is a beautiful stone.
This kind of nakayama ( I think it's karasu nakayama) is supposed to be very fine and very hard, one of the best of its kind. Check for inclusions, and inform us about its performance. If I'm allowed to ask, how much did it cost? 4-digit number?
According to the eBay listing it's not from Nakayama nor is it hard . It's from Hirayama & it's a medium soft uchigumori stone with Karasu colouring. I'm not sure but I think the listing implies it's a prepolisher to be followed up with a harder finisher. You should contact the seller on how he used it & where he would place it in a progression. Uchigumori is a stone not commonly used on razors but more for sword polishing.
That is how the listing describes the stone onimaru i tried doing a search using the key words in the description karasu,hirayama and could not find anything much .I will just have to see how it performs and where it fits into the progression.
The seller is a straight razor user. You could do worse than to ask for his input on usage but experiment by all means. It's a great way to learn.
I will send him a message and see where he would use it ,he does say he used it with razors ,so i will see what he says.
onimaru55 is total right it is Ohira Karasu pretty soft ones probably from Tenjyou, more for tools stone because sometimes you can feel those lines on this stones with knives and with razors.
In any case a good looking stone. You will find that the Nakayama karasu have bolder distinct mottling, the blacks look blacker and the grays look grayer and more even in their coloration and the stand out in contrast against each other. Ohira mine is famous for their uchigumori, and if your stone is from that strata this would not be considered a choice piece of uchigumori for sword polishing but it could be perfect for razors depending, as Maxim said about the lines.
For sword polishing you are looking for very even gray stones with distinct layering lines. Here are photos of actual uchigumori at Ohira mine showing how the stone looks as found, and after being split into finger stones for sword polishing. The next step would be to sand them thinner and to shape the edges and to next glue handmade mulberry paper to the back using an adhesive made from persimmion juice. These small finished pieces sell for tens of dollars and up into the hundreds of dollars per piece depending on the qualiy of grit regarding cutting speed and finess.
Making up these small finger stones creates enormous waste, most of the stone breaks into small unusable pieces and this is all done by hand, following the natural stratification of the stone. Because of this you cannot cut them with a saw as a saw does not by nature follow the grain in a gentle way. A dull nomi or chisel is used to seperate the layers, sort of like spliting wood for kindling. Better to use a dull axe for spliting. Alx

I asked him the same question and this was his reply -Quote:

Hang on and enjoy the ride
that pretty much means it is not a final finisher, it is a prepolisher.Quote:

It is great to start leanrning on a softer stone and then get a hard finisher.
I have a uchigumori, and it is great for razors. It is by far my favorite stone.. Let me throw in a disclaimer though. I am not a hone meister, just a shaving guy. I will say this though, i use it on my whacker st8tand some of my more sensitive edges and get great shaves from it. I understand with j-nats though there are different respoces from every stone...Quote:

I have finally had a chance to use this stone and i really like it it slurries up a treat puts a great polish on the blade feel like a coti,i havent shaved off the edge yet im am going to test it against the edge off a chinese 12k both solingen blades and SHARP.
The polishing it leaves, is it mirror like or haze-satin-matte? (this also depends on the wear resistance of the steel) From the experience I have with the flakes of this stone (hazuya), it slurries very easily, like a soft thuringian, with very good feedback, I would say it is more like a Turkish oilstone than a coticule, assuming we are talking for the same stone. Compare its edge with the other stones you have, and tell us the results.
Well i have just got myself a turkish oil stone so i will be able to compare them together when i get a chance,work and a baby dont leave to much of that at the moment but the holidays are nearly here and i will have a chance soon.
It took me a second to realize that "pasta" was just a typo for paste. I was completely baffled.... like, "What kind of witchcraft....?"Quote:
